Decribe the motion of a body following under gravity and write the related equation

Answers

Answer 1

It states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration an of its center of mass, or F = ma.

What is the body's equation of motion?

The fundamental equation of motion in classical mechanics is F = ma.

Since gravity affects an object's vertical motion, while it moves, it is said to be in motion under gravity.

The force that pushes objects downward is called gravity. In reality, gravity draws things toward the centre of the Earth. Homogeneous acceleration is experienced by a body in free fall.

Motion. It is said that the body is moving at an accelerated rate. Therefore, if a body falls freely while being affected by gravity, its velocity will begin to increase at a rate of 9.8 m/s2.

When a body falls freely under the effect of gravity alone in a vacuum, potential energy continuously decreases and kinetic energy continuously increases; as a result, the conservative force acts on the body.

What is the tenet of the Archimedes Principle?

According to Archimedes' principle, an object that is totally or partially submerged in a fluid will feel upward buoyant force that is equivalent in strength toward the point of gravity here on displaced fluid.

Where is the principle of Archimedes used?

The design principle for vessels and submarines uses Archimedes' principle. The Archimedes principle is the foundation of hydrometers.

According to Archimedes' principle:

F1 / A1 = F2 / A2

F2 = (A2 / A1) * F1

Also, the formula for the force is F = mg.

The formula for the area of the cylinder is A = , therefore we get

F2 = ( π [tex](r2)^{2}[/tex] / π [tex](r1)^{2}[/tex] ) * mg

Since the cylinders' diameter is 2 cm and 24 cm, r1 = 12 and r2 = 1.

Substituting the values to the derived equation, we get

F2 = ( π [tex](1)^{2}[/tex] / π [tex](12)^{2}[/tex] ) * 2000 * 9.8

2 = 136 N

how long after closing the switch s will the potential across each capacitor be reduced to 15.0 v ?

Answers

The time taken can be calculated by the equation: t = -RC ln(15/50)

To determine how long after closing the switch s the potential across each capacitor will be reduced to 15.0 V, we need to know the initial potential across the capacitors, the capacitance value and the resistance in the circuit.

When a switch is closed, the potential across a capacitor decreases exponentially with time according to the equation:

V(t) = V0e^(-t/RC)

Where V0 is the initial potential across the capacitor, t is time, R is the resistance in the circuit, and C is the capacitance.

In this case, the initial potential across each capacitor is 50.0 V, and the resistance in the circuit is 80 ohms.

To find the capacitance value we need to know that the capacitors are parallely connected, which means that the total capacitance is the sum of the individual capacitances:

Ctotal = C1 + C2

Once we have the capacitance value, we can find the time constant RC:

RC = R / Ctotal

Now we can use the equation above to find the time it takes for the potential to decay to a certain percentage of the initial value.

For example, if we want to find the time it takes for the potential to decay to 15.0 V (30% of the initial value), we can use the following equation:

15.0 V = 50.0 Ve^(-t/RC)

and we can solve for t:

t = -RC ln(15/50)

It's worth noting that this is an estimation and that in real world situations the resistance and capacitance values are also affected by other factors such as leakage current or parasitic capacitances.

8. Jax bounced a dodgeball off a wall. The dodgeball has a momentum of 32. 6 kg · m/s after the

collision. What is the total momentum of the system before the collision?

Answers

32. 6 kg m/s will be the total momentum of the system before the collision.

What does "collision" mean?

In physics, a collision is any circumstance in which two or more bodies rapidly apply forces to one another.

Despite the fact that the most common usage of the word "collision" relates to instances in which two or more objects smash violently, the scientific usage of the word makes no such assumptions.

If most or all of the total kinetic energy from the collision is lost (dissipated as heat, sound, etc., or absorbed by the objects themselves), the collision is said to be inelastic; such collisions result in the objects coming to a complete stop. A collision involving a car serves as an example of this type of collision since cars fold inward rather than colliding with one another.

Briefing:

pf = Final momentum of the system = 32.6 kg m/s

According to the principle of conservation of angular momentum we have

pi = pf => pi = 32.6 kg m/s

The wall is not moving so the initial and final momentum of the system are equal.

Therefore, the total momentum of the system before the collision is 32.6 kg m/s

The upper and lower fixed points of a mercury thermometer corresponds to 9.00mV and 16.50mV on the thermocouple thermometer. The temperature of a warm iron giving a reading of 11.21mV to the nearest whole number is.​

Answers

To find the temperature of the warm iron, we first need to convert the reading on the thermocouple thermometer to a temperature value. To do this, we will use the formula:

Temperature = (Reading - Lower Fixed Point) / (Upper Fixed Point - Lower Fixed Point) * (Upper Temperature - Lower Temperature) + Lower Temperature

In this case, the lower fixed point is 9.00mV and the upper fixed point is 16.50mV. We also know that the lower temperature is 0°C (the freezing point of water) and the upper temperature is 100°C (the boiling point of water). So, we can plug in these values:

Temperature = (11.21mV - 9.00mV) / (16.50mV - 9.00mV) * (100°C - 0°C) + 0°C

Simplifying, we get:

Temperature = (2.21mV / 7.50mV) * 100°C

And further simplifying, we get:

Temperature = 0.2907 x 100°C

So, the temperature of the warm iron is approximately 29.07°C to the nearest whole number.

If an object was traveling horizontally off a cliff at 6 m/s for 3 seconds, how long did it take to

Answers

The time taken by the object to hit the ground is 1.8 seconds.

What do you mean by gravitational force?

The attraction that draws two objects together is known as gravitational force, sometimes referred to as gravity. Every mass-containing object pulls on nearby things gravitationally in a sizable way.

The time it takes for an object to hit the ground after being dropped off a cliff can be calculated using the formula:

t = √(2*d/g)

where t is the time, d is the distance fallen, and g is the acceleration due to gravity.

In this case, we don't know the distance fell, but we can use the horizontal velocity and time of travel to find it:

d = v * t

where v is the velocity (6 m/s), and t is time (3 seconds)

d = 6 * 3 = 18 m

Now we can use the distance fallen to calculate the time it takes to hit the ground:

t = √(2*d/g)

g is approximately 9.8 m/s^2

t = √(2*18/9.8) = √ (3.6) = 1.8 seconds

So, it takes 1.8 seconds for the object to hit the ground after traveling horizontally off a cliff at 6 m/s for 3 seconds.

Answers

The balloon will be drawn to the wall once it has been rubbed sufficiently to build up a sufficient negative charge. Even though the wall should generally be neutrally charged, its charges can change, causing a positively charged region to pull the negatively charged balloon toward it.

The balloon gains electrons when it is rubbed against your hair or a piece of wool cloth, making it negatively charged. Once charged, the two balloons will move away from one another because like charges repel and like charges attract (the paper will be attracted to the charged balloons.)The pull of an electrostatic force is what keeps the ball clinging to the wall.The balloon becomes charged when we rub it with a synthetic cloth, and when it is brought close to a wall, the electrostatic force causes it to be drawn to the neutral wall.

We can find the torque of lever arm by the formula Torque(T)=Force * perpendicular distance.

A torque is an action that causes objects to rotate. A torque is required to rotate an object, just as a force is required to move an object in a line. Torque is created by force, but it also depends on where the force is applied and the point about which the object rotates.

Force and lever arm are not always perpendicular. When the force and lever arm are not perpendicular, trigonometry is required to calculate the length of the lever arm. The force applied is perpendicular to the surface of the object rotating. When this force is at an angle θ with the plane of the object, the perpendicular force requires the use of the sine function.

When an object is in rotational equilibrium, the net torque applied to it is zero. For example, if an object such as a see-saw is not rotating, you know the torque on each side is balanced Rotational equilibrium is often used to determine unknown forces.

At t = 0, a wheel rotating about a fixed axis at a constant angular acceleration of -0.40 rad/s2 has an angular velocity of 1.5 rad/s and an angular position of 2.3 rad. what is the angular position of the wheel at t = 2.0 s?

Answers

At t = 0, the wheel has an angular position of 2.3 rad and an angular velocity of 1.5 rad/s.

Since the wheel is rotating about a fixed axis at a constant angular acceleration of -0.40 rad/s2, we can use the equation for angular position to calculate the wheel's angular position at t = 2.0 s.

Angular position = initial angular position + (initial angular velocity × time) + (1/2 ×angular acceleration ×time²)

Angular position at t = 2.0 s = 2.3 rad + (1.5 rad/s × 2.0 s) + (1/2 ×-0.40 rad/s2 × (2.0 s)²)

Angular position at t = 2.0 s = 2.3 rad + 3.0 rad + -1.6 rad

It took the bike messenger 36 minutes to ride from the school to the blue house. If they are 2160 meters apart, what was the messenger's velocity

Answers

The bike messenger's velocity will be 1 m/s.

Given as per the question is,

Distance between school and the blue house is 2160 meters

Time taken by the bike messenger is 36 minutes

Velocity is to be calculated.

Converting minutes into seconds,

36 minutes = 36 X 60 = 2160 seconds.

Velocity of an object can be calculated by the formula as,

Velocity = Distance/ Time

Substituting the values as per the formula above,

Velocity = 2160/2160 = 1 m/s

draw the standing wave if the tension is quadrupled while the frequency is held constant

Answers

The diagram for the standing wave after the tension is quadrupled while the frequency is held constant has been attached and explained below.

We already know that the frequency of a standing wave is given by,

= f = nv/2l

and

= v = [tex]\sqrt{\frac{T}{m} }[/tex]

In the given problem, the frequency of the wave after the tension is quadrupled will be -

= f2 = 2v/2l

= f2 = v/l

= f2 = 1/l  [tex]\sqrt{\frac{T}{m} }[/tex]

Now, since we have quadrupled the tension, we have -

= f = 1/l  [tex]\sqrt{\frac{4T}{m} }[/tex]

= f = 2(f2)

So, now we know that the final frequency will be of this form(the image has been attached here) and it would look like this if the tension is quadrupled while the frequency is held constant.

An airplane starts from rest and accelerates at a constant 3.00 m/s2 for 30.0 s before leaving the ground. a. How far did it move

Answers

The airplane that starts from rest and accelerates at 1 constant 3 m/s2 for 30 s before leaving the ground moved by the distance of 1350m.

Acceleration is given as 3.00 m/s2

Time is 30 sec.

The formula we can use in this case is:

s = ut + 0.5 at^2

v = at + u

where,

s is distance travelled

u is initial velocity = 0 since at rest

t is time travelled

a is acceleration

v is the final velocity when it took off

a. s = 0 + 0.5 * 3 * 30^2

s = 1350 m

The distance moved by the airplane is 1350 m.

Read the excerpt below from the Yung Wing's book My Life in China and America published in 1909.In the fall of 1840, while the Opium War was still going on, my father died, leaving four children on my mother's hands without means of support.Fortunately, three of us were old enough to lend a helping hand. My brother was engaged in fishing, my sister helped in housework, and I took to hawking candy through my own village and the neighboring one. I took hold of the business in good earnest, rising at three o'clock every morning, and I did not come home until six o'clock in the evening. My daily earnings netted twenty-five cents, which I turned over to my mother, and with the help given by my brother, who was the main stay of the family, we managed to keep the wolf away from our door. I was engaged in hawking candy for about five months, and when winter was over, when no candy was made, I changed my occupation and went into the rice fields to glean rice after the reapers. My sister usually accompanied me in such excursions. But unlike Ruth of old, I had no Boaz to help me out when I was short in my gleaning. But my knowledge of English came to my rescue. My sister told the head reaper that I could speak, read and write English. This awakened the curiosity of the reaper. He beckoned me to him and asked me whether I wouldn't talk some "Red Hair Men" talk to him. He said he never heard of such talk in his life. I felt bashful and diffident at first, but my sister encouraged me and said "the reaper may give you a large bundle of rice sheaf to take home." This was said as a kind of prompter. The reaper was shrewd enough to take it up, and told me that if I would talk, he would give me a bundle heavier than I could carry. So I began and repeated the alphabet to him. All the reapers as well as the gleaners stood in vacant silence, with mouths wide open, grinning with evident delight. A few minutes after my maiden speech was delivered in the paddy field with water and mud almost knee deep, I was rewarded with several sheaves, and I had to hurry away in order to get two other boys to carry what my sister and I could not lug. Thus I came home loaded with joy and sheaves of golden rice to my mother, little dreaming that my smattering knowledge of English would serve me such a turn so early in my career. I was then about twelve years old. Even Ruth with her six measures of corn did not fare any better than I did.Yung Wing tells briefly of his father's death.
