A pool cue ball moving at 2.1 m/s east collides in a straight line with the eight ball at rest. (You may assume that the cue ball and the eight ball have the same mass.) Find the velocity of the eight ball after the collision if momentum is conserved and
the cue ball stops
the cue ball continues on in the same direction at 0.10 m/s
the cue ball continues on in the same direction at 0.70 m/s.

Answers

1. 2.1 m/s west.

2. 2.0 m/s west.

3. 1.4 m/s west.

Momentum is a conserved quantity, meaning that it is neither created nor destroyed. This means that the total momentum of the system (cue ball and eight ball) before and after the collision must stay the same. After the collision, the momentum of the system is equal to the momentum of the eight ball alone since the cue ball no longer has momentum after it stops (for option 1) or has a different momentum depending on its speed (for options 2 and 3).

Since momentum is mass times velocity, we can solve for the velocity of the eight ball by rearranging this equation:

Momentum = Mass x Velocity

Velocity = Momentum / Mass

Plugging in the given values:

1. Velocity = (2.1 m/s east) / (mass of both balls) = 2.1 m/s west

2. Velocity = (2.1 m/s east + 0.10 m/s east) / (mass of both balls) = 1.9 m/s west

3. Velocity = (2.1 m/s east + 0.70 m/s east) / (mass of both balls) = 1.4 m/s west

The magnitude of the gravitational force acting on the satellite is 3.16 x 10^22 N.

How calculate the gravitational force?

The gravitational force between two objects can be calculated using Newton's Law of Universal Gravitation: F = G * (m1 * m2) / r^2, where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers.

To calculate the gravitational force acting on the satellite, we need to know the mass of the satellite (m1) and the distance between the center of Earth (m2) and the center of the satellite (r).

The mass of the satellite is given as 1,500 kg

The distance between the center of Earth and the center of the satellite is the distance from the surface of Earth to the satellite + the radius of Earth:

r = (1 Earth radius + 6.37 x 106 m)

We can use the given information to calculate the force of gravity acting on the satellite:

F = G * (m1 * m2) / r^2

F = (6.67 x 10^-11 N*(m^2)/(kg^2)) * (1,500 kg * 5.97 x 1024 kg) / (6.37 x 106 m + 6.37 x 106 m)^2

A block with the mass of 14.26kg is on a ramp with an incline of 41 degrees. If the block is stationary, what is the minimum value of the coefficient of static friction? [Please explain to me how you did it, I'm giving you 50 points lol the last two times I've asked ive gotten either no explanation or a link to a calculator...]

Answers

The minimum value of the coefficient of static friction is 1.33.

What is the coefficient of static friction?

To calculate the minimum value of the coefficient of static friction, we need to determine the force of static friction acting on the block. The force of static friction is equal to the force of gravity acting on the block (mg) multiplied by the coefficient of static friction (µs

m = 14.26kg

θ = 41°

g = 9.8 m/s²

The force of gravity acting on the block is given by the formula:

Fg = mg

where,

m =  (mass of the block)

g =  (acceleration due to gravity)

Fg = 14.26kg *9.8 m/s²

Fg = 139.75 N

The force of static friction can be found using the formula:

Fstatic = µs * N

where,

µs = coefficient of static friction (unknown)

N = Normal force acting on the block

The normal force acting on the block is equal to the force of gravity acting on the block perpendicular to the ramp.

N = mg * cos(θ)

where,

θ = 41 degrees (incline of the ramp)

N = 14.26kg * 9.8 m/s² * cos 41°

N = 105.47 N

So,

Fstatic = µs * (mg * cos(θ))

making µs subject of the formula and substituting already calculated vaues we get,

µs =      Fstatic

          (mg * cos(θ))

µs =    139.75 N

         105.47 N

µs = 1.33

This is the minimum value of the coefficient of static friction.

A 2 kg book is sitting on a table. A 10 n force is pulling to the right. A 3 n force is pulling to the left. What is the net force acting on the book?.

Answers

The net force acting on the book is 7N right.

The net force is defined as the total of all forces exerted on an object. Net force is essential since it aids in describing the motion of an item and can be used to calculate acceleration. The first law of motion of Isaac Newton states that an object in motion will remain in motion and an object at rest will remain at rest unless acted upon by a net force that is imbalanced. This indicates that knowing the net force acting on an object will aid in predicting its velocity.

In this case, we are given that:

Force F1 = 10 N pulling to the right

Force F2 = 3 N pulling to the left

Let's assume the right is positive and the left is negative.

To calculate the net force, we can use this following formula:

Fnet = F1 + F2

Fnet = 10 + (-3)

Fnet = 7

As the result, the net force would be 7 N.

Answers

The distance moved by an object when it acted by a net force 1 N and time 3s is found to be 0.9m

Why is mass acceleration due to net force?

According to this, an object's rate of change in velocity is directly proportional to the force used and moves in the direction of the applied force. The equation: summarises it. Mass (kg) times acceleration (m/s2) equals force (N). A constant mass item will therefore accelerate in direct proportion to the force exerted.

F = ma

acceleration = F/m => 1/5

v= u + at, u=0 (initially at rest);

v=at = distance/t = at;

S = distance => ut + 1/2at^2

=> 0 + 1/2 x 1/5 x 9 => 0.9m

the distance traveled by object in the given time 3s = acceleration x t2

How is acceleration calculated?

The acceleration is determined by dividing the net force by the mass. An object's acceleration doubles if the net force exerted on it also doubles. Increased mass will result in a halving of acceleration. If the mass and net force are both doubled, the acceleration will remain constant.

Recently, I did an experiment on pressure and volume. When I decreased the volume, the pressure decreased, and when I increased the volume, the pressure decreased, like normal. However, when increasing the volume, the pressure recorded was slightly higher than when decreasing the volume. What is the reason for this (I'm sorry for being unable to attach a photo of the results)

Answers

The relationship between pressure and volume is described by Boyle's Law, which states that at a constant temperature, the pressure and volume of a gas are inversely proportional. This means that as the volume increases, the pressure decreases, and as the volume decreases, the pressure increases.

However, it is important to note that the relationship between pressure and volume is not always perfect and there are many factors that can affect the measurements. For example, if the apparatus used to measure the pressure and volume is not calibrated properly, or if there is a leak in the system, this can lead to inaccurate results. Additionally, external factors such as temperature changes or the presence of impurities in the gas can also affect the measurements.

It is possible that the reason for your observation is an experimental error, or if not, it could be that you have discovered something new or an exception to the Boyle's Law. I recommend you to repeat the experiment and check your measurements and equipment, also double check your calculations and notes.

When is there a decrease in air pressure on top of a plane's wing?
A)as the plane's speed decreases
B)as the plane's fuel runs low
C)as the plane's speed increases

Answers

Answer: Option C.

Explanation:

As the speed of plane increases and it moves forward it allows to push air on the bottom of the wings of the plane which results in increasing the pressure

The fact of air pressure on top of planes wing decreases with the increase bin plane's speed is based on Bernoulli’s Principle which states that with the fast moving air, the pressure decreases.

Therefore,n when the plane moves up it's wing pushes air down and on the same time the air pressure decreases at the top of the wing, this difference between the high and low pressure allows the flight to lift up.

Hence, the correct option is C.

Uniform circular motion is the motion of an object in a circular path with a constant speed and the direction of velocity is perpendicular to the direction of acceleration. Examples of objects that experience uniform circular motion are wheels and clockwise motion where these objects have a constant linear speed, constant angular velocity, and constant centripetal acceleration. The speed in the circular motion of the object is also called the tangential speed where the object is moving in a circle in the direction of offending its spin path.

A convex mirror forms an image of half the size of the object. When it is moved 15 cm away from the object, the size of the image becomes 2/5 times the size of object. Find the focal length of convex mirror. Answer is 30.

Answers

Answer:

  focal length = 30 cm

Explanation:

You want the focal length of a convex mirror when moving the mirror an additional 15 cm away from the object causes its image size to decrease from 1/2 to 2/5 the size of the object.

Mirror equation

The relation between focal length (f), object distance (do) and image distance (di) is ...

  1/f = 1/do +1/di

The ratio of heights is the same as the ratio of distances:

  hi/ho =di/do

Application

If we let do represent the original object distance, then (1/2)do = di, the original image distance. This gives one equation we need:

  1/f = 1/do +1/(1/2do) = 3/do

Moving the mirror increases the object distance to (do+15). Now, the equation becomes ...

  1/f = 1/(do+15) +1/(2/5(do+15)) = 7/(2(do+15))

Solution

Substituting for 1/f, we have ...

  3/do = 7/(2(do +15))

  6(do +15) = 7do . . . . . . . . . cross multiply

  90 = do . . . . . . . . . . . . subtract 6·do

Then the focal length is ...

  1/f = 3/do

  f = do/3 = 90/3 = 30

The focal length of the mirror is 30 cm.

Answers

Answer: 11 meters

Explanation: i'm rlly sorry if i am wrong

To calculate the depth of the well, we can use the equation:

distance = 1/2 * acceleration due to gravity * time^2

Where distance is the depth of the well, acceleration due to gravity is 9.8 m/s^2, and time is the time it takes for the penny to fall to the bottom of the well.

Plugging in the given value of time = 1.5 seconds and acceleration due to gravity = 9.8 m/s^2.

Distance = 1/2 * 9.8 * (1.5)^2 = 11.55 meters

So the depth of the well is approximately 11.55 meters.

The person will do 8222.3 Joules of work on the sled if she drags it.

What does "work" mean in physics?

Work is a physics term used to describe the energy transfer that takes place when an object is moved over a distance by an external force, at least some of that is applied in the direction of the displacement.

Given, angle made by the rope θ = 20°

displacement, s = 125m

force, F = 70N

Positive work is done by the force's displacement-direction component.

W = Fcosθ.s

W = 70N(cos20°)125m.

W = 8222.3 Joules

Since it is perpendicular to the distance, the force's vertical component does NOTHING. In other words, it is ineffective at moving the sled. Since it is the horizontal component of the force that moves the object, it is effective.

The person will do 8222.3 Joules of work on the sled if she drags it.

The volume of gas kept at a constant pressure varies inversely with the temperature t. If the temperature is 50 degrees, the volume is 20 cubic feet. What will the volume be when the temperature is 100 degrees?.

Answers

The volume of that gas in the 100 degrees temperature will be 100 cubic feet. The condition of the area is isobar or the same pressure. Hence, you have to formulate the solution based on isobars formula.

How to calculate the volume for that condition?

As per data given, previous volume (V1) = 20 cubic feet; previous temperature (t1) = 50 degrees; current temperature(t2) = 100 degrees. the condition of the area is in the constant pressure or isobars. The formula we will use in the isobar is V1 : V2 = t1 : t2. So, the calculation would be:

V1 : V2 = t1 : t2

20 : V2 = 20 : 100

20 V2 = 20 x 100

V2 = 100 cubic feet

Which statement best summarizes the information in the paragraph? Earthquakes may occur at all types of plate boundaries. The strength of an earthquake depends on the type of boundary. All earthquakes at plate boundaries result from forces underneath Earth’s surface or volcanic eruptions. Different types of plate interactions result in earthquakes of varying strengths at various depths.

Answers

Different types of plate interactions at plate boundaries can cause earthquakes of varying strengths, at various depths, which can be caused by both forces underneath Earth's surface and volcanic eruptions.

What is plate interaction?

Plate interactions refer to the forces and mechanisms that cause the movements and interactions of the Earth’s plates. These interactions are driven by convection currents in the Earth’s mantle, which are generated by the heat energy released by the Earth’s core. The plates move in different directions, resulting in different types of plate interactions. The most common type of plate interaction is called divergent boundaries, which occur when two plates move away from each other.
