A satellite is in orbit-like 595 km above the earth's surface. (a) What is its orbital velocity? Earth's radius is 6.37 x 10 m, earth's mass is 5.98 x 104 kg. (b) What is the centripetal acceleration acting on the satellite?

Answers

The satellite's orbital velocity is 7.7 x 10^3 m/s. As a result, the satellite's centripetal acceleration is 7.6 x 10^-3 m/s2.

What is velocity?

Velocity is the directional speed of a moving object as an indicator of its rate of change in location as perceived from a certain frame of reference and measured by a specific time standard. Velocity is defined as the speed of a body in a certain direction. Velocity is defined as the rate of change in displacement with respect to time. The amount and direction of velocity are both vector variables. The direction of movement of the body or item is defined by velocity. Speed is fundamentally a scalar number. Velocity is, in essence, a vector quantity. It is the pace at which distance changes. It is the displacement rate of change.

Here,

a) To find the orbital velocity of the satellite, you need to use the formula:

v = (GM/r)^0.5

Plugging in the values, you get:

v = (6.67 x 10^-11 x 5.98 x 10^24 / (595 x 10^3 + 6.37 x 10^6))^0.5

v = 7.7 x 10^3 m/s

b) To find the centripetal acceleration, use the formula:

a = v^2 / r

Plugging in the values for v and r, you get:

a = (7.7 x 10^3)^2 / (595 x 10^3 + 6.37 x 10^6)

a = 7.6 x 10^-3 m/s^2

The orbital velocity of the satellite is  7.7 x 10^3 m/s. So, the centripetal acceleration acting on the satellite is 7.6 x 10^-3 m/s^2.

what can you conclude about the inflated balloon? is the balloon going to rise, fall or stay stationary?

Answers

The balloon initially rises in air because the weight of the displaced air i.e. the weight of the helium and the balloon is less than the upthrust. The balloon comes to a stop at a specific height because the density of air decreases with height.

A balloon's walls are put under pressure when it is inflated because the air inside the balloon expands. The balloon's size consequently grows.

A balloon that has been filled with helium gas can float in the air for around six hours. This is referred to as helium gas inflation. A balloon can be inflated with regular air using a balloon pump or an electric pump, but the balloon will not float.

Bubble balloons and foil balloons can last days, weeks or even months. They last far longer than latex balloons because helium progressively leaks out of latex balloons since they are porous.

What is frictional force?

Friction is the force that opposes relative motion between two objects in contact. Frictional force is the force that opposes the motion or tendency of an object to move when in contact with another object. It acts in the opposite direction to the applied force. The magnitude of the frictional force depends on the nature of the surfaces in contact, the normal force between the surfaces, and the coefficient of friction between the surfaces.

a. The weight of the motorcycle and rider can be found using the formula:

Weight (N) = mass (kg) * 9.8 m/s^2

The mass of the motorcycle and rider is 250 kg, so:

Weight = 250 kg * 9.8 m/s^2 = 2450 N

b. The normal force is equal to the weight of the motorcycle and rider:

Normal force = 2450 N

c. Frictional force can be found by subtracting the force produced by the engine from the weight:

Frictional force = Weight - Engine force

Answers

The angle so that its range is ten times the maximum height of its trajectory is in the range of 0 to 90 degrees.

The range of a projectile can be calculated using the following formula:

Range = (V^2 sin(2θ)) / g

where V is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity (9.8 m/s^2).

If the range is to be ten times the maximum height of the trajectory, we can equate the range and ten times the maximum height:

Range = 10 * (V^2 sin(θ)^2) / (2g)

Answers

In an interference pattern of same frequency a. Wavelength is 82 cm b. Wavelength will not be different if we take a point on the nodal line on the left c.  Frequency of the sources is approximately 0.1159 Hz

In interference pattern:

a. To calculate the wavelength, we can use the formula for the distance between two points in an interference pattern, which is given by d = λ/2, where d is the distance between the two sources and λ is the wavelength of the wave.

Since we know that the distance from one source to the point on the second nodal line on the right from the center is 25 cm and the distance from the other source to the same point is 34 cm, we can calculate the total distance between the two sources as follows:

d = √(25^2 + 34^2) = 41 cm

Therefore, the wavelength is given by:

λ = 2d = 2 * 41 cm = 82 cm

b. The wavelength will not be different if we take a point on the nodal line on the left, because the wavelength of a wave is a characteristic property of the wave and is independent of the location of observer.

c. To calculate the frequency of the sources, we can use the formula for the wave speed, which is given by v = fλ, where v is the speed of the wave, f is the frequency of the wave, and λ is the wavelength of the wave.

In this case, we know the speed of the wave (v = 9.5 cm/s) and the wavelength (λ = 82 cm), so we can calculate the frequency as follows:

f = v/λ = 9.5 cm/s / 82 cm = 0.1159 Hz

A 10-kg crate sits on a horizontal floor. The maximum static friction that could be exerted on the crate is 58.8 N.

What is Static Friction ?

An object moving along a path is resisted by a force known as static friction. Lastly, use an easy example to comprehend it. Think about the activity we perform frequently called walking. We are constantly in contact with the floor while we work. Motion presses against the ground as we move it backward, and we then advance our feet.

One key concept to be aware of in order to minimize friction is the fact that it operates in the opposite direction from relative motion. This phenomenon may be useful for reducing the speed of the action until it eventually comes to a stop.

The force needed to move the crate is equal and opposite to the maximum force of static friction Fs=μsmg

where μs is the coefficient of static friction.

Therefore, the magnitude of the force parallel to the floor is

Answers

To produce an acceleration to a system, there must be a net force on the system.

Acceleration is the rate of change of velocity with respect to time. In other words, it is the measurement of how quickly an object's velocity changes over a period of time.

Acceleration can be described as positive, negative, or zero, depending on whether an object is speeding up, slowing down, or moving at a constant velocity. It is a vector quantity, with both magnitude and direction, and is typically measured in meters per second squared (m/s^2).

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. So, for an object to accelerate, there must be a net force acting on it, whether it's a single force or the result of multiple forces acting in different directions.

The presence or absence of acceleration outside the system is not a factor in determining the acceleration of the system.

Therefore, To produce an acceleration to a system, there must be a net force on the system.

A toy car is moving in a straight line while its speed is decreasing. What is the sign of its acceleration? A. positive B. negative C. The sign cannot be determined without more information.

Answers

Option B. Positive. The sign of acceleration depends on the direction of the change in velocity. If the speed of the toy car is decreasing, then its velocity is decreasing, which means that its acceleration is negative.

The sign of acceleration depends on the direction of the change in velocity. If the velocity is increasing, the acceleration is positive. If the velocity is decreasing, the acceleration is negative. If the velocity is staying the same, the acceleration is zero. To determine the exact sign of acceleration, more information is needed, such as the direction and magnitude of the change in velocity over time. The change in velocity, also known as the delta velocity, is defined as the difference between the final velocity and the initial velocity. The change in velocity can be positive if the final velocity is greater than the initial velocity, negative if the final velocity is less than the initial velocity, or zero if the velocity is constant. The change in velocity can be used to calculate the acceleration, using the equation: acceleration = change in velocity / time.

You observe a ball that moves (33.6 ‡ 0.2) cm in (11.49 ‡ 0.02) s. What is the observed speed of the ball (best estimate and most probable uncertainty)? (speed =distance / time)• (2.92 + 0.01) cm/s• (1.62 ÷ 0.01) cm/s• (2.92 ‡ 0.02) cm/s• (1.619 ÷ 0.008) cm/s(1.739 + 0.005) cm/s

Answers

The formula for speed is speed = distance/time. Using the given values, we can calculate the observed speed of the ball as follows:

distance = 33.6 ‡ 0.2 cm

time = 11.49 ‡ 0.02 s

speed = distance / time = (33.6 ‡ 0.2) cm / (11.49 ‡ 0.02) s

Using the most probable uncertainty (±0.5 times the smallest uncertainty), we can estimate the uncertainty in the speed calculation as follows:

uncertainty in distance = 0.2 cm

uncertainty in time = 0.02 s

uncertainty in speed = (uncertainty in distance) / (time) ± 0.5 * (smallest uncertainty)

= (0.2) / (11.49) ± 0.5 * (0.02)

= 0.01744 ± 0.01 cm/s

Therefore, the observed speed of the ball is (2.92 ± 0.02) cm/s.

will i run down my car battery if i'm cranking the engine with the windshield wipers running unchecked?

Answers

Using windshield wipers running unchecked will drain battery.

The most common reason a car battery is draining is parasitic drain caused by a faulty electric consumer like a bad door lock switch or a trunk lock switch. It can also be caused by a broken alternator or human errors, like forgetting electric consumers on.A parasitic drain occurs when something in the vehicle continues to run even though you have turned the car off. There are some components that are always using battery power, such as the memory for the clock or radio presets.However, when an electrical problem occurs, the parasitic drain might exceed what is normal. These drains occur due to defective fuses or faulty wiring.

According to coulomb's law, doubling the distance between two charges will change the force by a factor of 1/4.

Definition of Coulomb's Law

Coulomb's law is a law that governs the interaction between electric charges, both like and different types of charges. As you know that there are positive and negative electric charges.

Who Discovered Coulomb's Law

Coulomb's law was discovered by a scientist from France, namely Charles-Augustin de Coulomb in 1785. Before discovering the law of the interaction between electric charges, Coulomb had done a lot of research, starting from making compasses, making torsion scales, making works on electricity and magnetism, and much more. other.

Several of Coulomb's works on electricity and magnetism were used as the basis for research and discoveries by later scientists, such as Hans Christian Oersted, Marie Ampere, to Henry Cavendish.

Energy is not only stored in biomass. Some of it is used for biological processes. Which process produces offspring?.

Answers

Biomass is not the only way to store energy. It's utilised in some biological activities. The procedure that results in offspring is referred to as reproduction.

The power used to carry out a task is known as energy. Although energy cannot be generated, it may be moved and transformed into several forms. Through the process of photosynthesis, plants utilise the energy from sunlight to create food, which is subsequently stored in the form of biomass. When plants are consumed by herbivores and other animals, the energy is then transferred to other living creatures.

Reproduction, which takes place when an egg and sperm combine to produce a foetus, is the process of creating children. The sperm neck requires an energy source to be able to move actively during.

what is the correct voltage 48.0 if the selector switch is in the 200v position?

Answers

The correct voltage is 200 volts.

Voltage is the electrical potential difference between two points in an electrical circuit, expressed in volts. It is the force that causes current to flow through a circuit.A selector switch is a type of switch used to select one of a number of circuit configurations. Selector switches are usually used to change the state of a system or device, such as switching between two different power sources or activating a specific function within a circuit.

The equation is:

[tex]Vout = \frac{Vselector * 48.0 }{ 100}[/tex]

where Vout is the output voltage, Vselector is the selector switch voltage, and 100 is the default selector switch voltage. In this case,

[tex]Vselector = 200 volts[/tex],

[tex]Vout = \frac{200 * 48.0 }{ 100 }\\\\Vout = 48 volts.[/tex]

The correct voltage would be 200v. This is because when the selector switch is in the 200v position, the voltage is multiplied by the ratio of [tex]\frac{48.0}{200} = 0.24[/tex], resulting in a voltage of 200v

The car was initially traveling at 15 m/s. The car slows with a negative acceleration of 4.5 m/s2. How long does it take the car to slow to a final velocity of 4.0 m/s?
A. 0.89 s
B. 2.4 s
C. 11 s
D. 60 s

Answers

Option A.To calculate the time it takes for a car with initial velocity 15 m/s to slow down to a final velocity of 4 m/s, we can use the following formula:

Δt = (vf - vi) / a

Where:

Δt is the change in time

vf is the final velocity

vi is the initial velocity

a is the acceleration (negative in this case, since the car is slowing down)

Δt = (4 - 15) / -4.5

Δt = 11 / -4.5

Δt = -2.44

Since time can't be negative, we have to take the absolute value of Δt:

Δt = |-2.44| = 2.44 s

Rounding up to the nearest hundredth, we get:

Δt = 2.44 s ≈ 2.44 s = 0.89 s

Two spherical conductors are separated by a large distance. They each carry the same positive charge Q. Conductor A has a larger radius than conductor B.

Compare the potential at the surface of conductor A with the potential at the surface of conductor B.

a. VA > VB

b. VA = VB

c. VA < VB

Answers

Electric potential on Conductor A will be lesser than electric potential on Conductor B.It means VA < VB.So,correct option is c.

The electric potential (likewise called the electric field potential, expected drop, the electrostatic potential) is characterized as the need might have arisen to move a unit of electric charge from a reference highlight the particular point in an electric field. All the more definitively, it is the energy per unit charge for a test charge that is little to the point that the unsettling influence of the field viable is immaterial.

Moreover, the movement across the field should continue with immaterial speed increase, to stay away from the test charge getting motor energy or delivering radiation. By definition, the electric potential at the reference point is zero units. Regularly, the reference point is earth or a point at limitlessness, albeit any point can be utilized.

We know that for sphere electric potential is given by the below formula

V=Q/4π∈₀r

It means V is inversely proportional to radius of sphere.

Since,conductor A has larger radius as compared to conductor B,so electric potential of conductor A will be lesser than as compared to conductor B.

Hence, option c is correct.

which part of the spectrum is absorbed and which part reflected when white light falls on the blue sweater? to select the answer, click on the outer grey edge of the spectrum adjacent to the appropriate part.

Answers

Only blue light can be reflected or transmitted by a substance that absorbs wavelengths longer than blue.

Is all light reflected in white?

We are aware that white items reflect white light because they contain white pigments. White things reflect all light and do not absorb any since white is the culmination of all light.

Only red and green light will be reflected off the garment if it absorbs blue light. As a result, only red and green light will reflect from the shirt when red, green, and blue light are shining upon it. Because yellow always appears when red and green light strike your sight, the garment will appear yellow. This serves to clarify how color subtraction works.
