Diana raises a 1000. N piano a distance (Links to an external site.) of 5.00 m using a set of pulleys. She pulls in 20.0 m of rope. How much work was done on the object

Answers

Answer 1

The 5000 N-m work was done on the object.

How is labor done measured?

The formula Work = Force * Distance can be used to compute work. The joule (J) or Newton-meter (N-m) is the SI unit for work. When 1 N of force pushes an item a distance of 1 m, the work done is equal to 1 joule.

What kind of work is an example?

There are several instances of work being done in our daily lives. A student holding a backpack on his back or his shoulder full of books, a horse pulling a plow across the field, a father pushing a supermarket cart in a mall, and many more examples come to mind.

What is the mass of a softball if it hit the catcher's glove traveling at
48.7 m/s2 and struck with a force of 51.3-Newton?

Answers

Answer:

To solve this problem, you can use the formula F = ma, where F is the force applied to an object, m is the mass of the object, and a is the acceleration of the object. In this case, the force applied to the object is 51.3 newtons and the acceleration of the object is 48.7 m/s2. So, you can set up the equation like this:

51.3 newtons = m x 48.7 m/s2

To solve for the mass of the object, you can divide both sides of the equation by 48.7 m/s2:

51.3 newtons / 48.7 m/s2 = m x 48.7 m/s2 / 48.7 m/s2

This simplifies to:

1.05 kg = m

So, the mass of the softball is approximately 1.05 kilograms.

Eileen is holding a pillow with a mass of 0.30 kg when Stephanie decides she wants it and tries to pull it way from Eileen. If Stephanie pulls horizontally on the pillow with a force of 10.0 N and Eileen pulls with a horizontal force of 11.0 N, what is the magnitude of the net acceleration of the pillow

Answers

The magnitude of the net acceleration of the pillow is 3.333 m/s^2 .

How do you determine the magnitude of the net acceleration?

To determine the magnitude of the net acceleration of the pillow, we can use Newton's Second Law of Motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration:

Fnet = ma

where

Fnet = net force acting on the pillow

m = mass of the pillow (0.30 kg)

a = acceleration of the pillow

Fnet = FStephanie - FEileen = 10 N - 11 N = -1 N

So, the net force acting on the pillow is -1N

Now, we can use Newton's Second law to find the acceleration of the pillow

a = Fnet/m = -1 N / 0.3 kg = -3.333 m/s^2

Therefore, the magnitude of the net acceleration of the pillow is 3.333 m/s^2 .

a 0.30g fly moving at 1.5ms-1 is trappedby a spiders web the fly comes to rest in a time of 0.40s calculate the magnitude of the change in momentum if the fly and the average firce exerted by the web on the fly​

Answers

Answer:

Magnitude of the change in momentum = 0.45kgms-1

Force exerted = 1.13N

Explanation:

The magnitude of the change in momentum of the fly can be calculated using the equation Δp = mv, where m is the mass of the fly and v is the velocity of the fly. In this case, the fly has a mass of 0.30g and an initial velocity of 1.5ms-1. Therefore, the change in momentum of the fly is

Δp = (0.30g) x (1.5ms-1) = 0.45kgms-1.

The average force exerted by the web on the fly can be calculated using the equation F = Δp/Δt, where F is the average force, Δp is the change in momentum of the fly, and Δt is the time taken for the fly to come to rest. In this case, the change in momentum of the fly is 0.45kgms-1 and the time taken for the fly to come to rest is 0.40s. Therefore, the average force exerted by the web on the fly is

F = (0.45kgms-1)/(0.40s) = 1.13N.

A 26 kg crate initially at rest on a horizontal floor requires a 70 N horizontal force to set it in motion. Find the coefficient of static friction between the crate and the floor.

Answers

The coefficient of static friction between the crate and the floor is calculated to be 0.275.

The frictional force when an object moves on the horizontal surface is given as,

Ff = μ N

where, N is the normal force

μ is the coefficient of static or kinematic friction

If no forces other then the weight and the normal are acting upon the y-direction, then the weight and the normal force are equal in magnitude.

N = W = m g

Given that,

Mass of the crate = 26 kg

Frictional force Ff = 70 N

Weight of the crate = 26 × 9.8 = 254.8 N

The normal force is 254.8 N.

The coefficient of static friction μ = Ff /N = 70/254.8 = 0.275

Thus, the coefficient of static friction between the crate and the floor is 0.275.

What factors interact with one another to keep a satellite in orbit. Describe two physics concepts and the effects each has on satellite orbit.

Answers

Two physics concepts that interact with one another to keep a satellite in orbit are the gravitational force and the centrifugal force.

The apparent outward force that a rotating mass experiences is known as centrifugal force. Imagine a ball being whirled around on a string or the outward motion you experience when driving around a curve. Since the system is not rotating in an inertial frame, there is no outward acceleration. The ball or your body just continues to go in the same direction that they did at first. However, they seem to be accelerating away in the rotating reference frame of the string or the car. The direction of centrifugal force is always outward and away from the axis because the Earth revolves around a fixed axis. Thus, in the equator and at the poles of the Earth, it is the opposite of the direction of gravity.It is zero at the poles of the Earth.

One of the four fundamental forces of the universe is gravity. A centripetal force is necessary in nonlinear motions like the planetary motion. In the study of disciplines like astronomy, physics, space exploration, cosmology, and many others, both of these forces are crucial.

A The fish decreased its buoyant force by decreasing its density. B The fish increased its buoyant force by increasing its density. с The fish increased the buoyant force by reducing its density.

Answers

The situation will be describe with:

C. The fish increased the buoyant force by reducing its density.

THE SWIM BLADDER

A swim bladder is an internal organ that some fish use to control their buoyancy. The fish can adjust the amount of gas in the swim bladder to make itself more or less dense than the water around it. In order to rise toward the surface of the water, the fish would need to decrease its density relative to the water, which it can do by increasing the amount of air in its swim bladder. This increase in air in the swim bladder reduces the fish's density, which in turn increases its buoyancy and allows it to rise to the surface.

There are different ways that a fish can control its buoyancy, and different species of fish may have different adaptations for doing so. Some fish may have other organs or structures that can be used to control buoyancy, such as lipids in their body tissue, or fins that can be used to control their position in the water.

Additionally, some fish may have the ability to change their shape or size in order to control their buoyancy, such as by swallowing air or by compressing their swim bladder. However, in general, the most common way for fish to control buoyancy is by adjusting the amount of gas in their swim bladder.

Does a heavier object go down a ramp faster?

Answers

A heavier object go down a ramp at a same pace as a lighter object go down a ramp because of gravitational force acting on it in a major form and the rolling tangential force acting on it in a smaller manner..

Rolling motion happens when an object roll over from a ramp or any other sloppy surface whether it is rough or smooth. many forces act on it at the same moment. also in many forces rolling tangential force and gravitational force is also acting on it at the same moment. in which the gravitational force is acting on it at a bigger pace and plays an important role in rolling of the object from the ramp or any other sloppy surface. hence, by this information we can firmly consider that a heavier object go down a ramp at a same pace as a lighter object go down a ramp because of gravitational force acting on it in a major form.

What is better static or dynamic stretching?

Answers

Explanation:

This intense stretching method uses bouncing movements to push your body beyond its normal range of motion. Whereas static stretches are performed slowly and gradually, the ballistic method stretches muscles much farther and faster. You can do many of the same stretches as ballistic or static stretches.
