Define output work and input work

Olenka [21]

Answer: Input work is the work done on a machine as the input force acts through the input distance.Other ways it would be the work done on a body or system, that is, forces that are applied to the body or system. This is in contrast to output work which is a force that is applied by the body or system to something else.Output work is the work done by a machine as the output force acts through the output distance. The machine does to the object to increase the output distance.

A steel ball moves from a position of +125 meters to a position of -75 meters. This motion takes 90.0 seconds. What is the veloc

bonufazy [111]

Answer:

2.22m/s to the left

Explanation:

Given parameters:

Initial position = +125m

Final position = -75m

Motion time = 90s

Unknown:

Velocity of the steel ball = ?

Solution:

The velocity of the steel ball is given as the displacement divided by the time;

Velocity = $\frac{displacement}{time}$

The net displacement of the ball = 125- (-75) = 200m to the left

Input the parameters and solve for the velocity;

Velocity = $\frac{200}{90}$ = 2.22m/s to the left

Which of the following is an example of a force? Question 13 options: a) push b) pull c) inertia d) both A and B e) all of the a

kupik [55]

Hey there! :D

Force is energy or strength that as the characteristic of movement or physical action.

A push or pull is a force. It moves something physically. If I was going to push a door for it to open, I would physically be moving it.

Inertia is a common tendency to remain unchanged or do nothing. If you are not doing anything, you are not applying force or movement to anything. This would not be the correct answer. We can eliminate "C" and "E"

Since a push and pull both are a force, then "D" is the answer. They both are.

I hope this helps!

The velocity time graph of a car shown below a) Calculate the magnitude of displacement of the car in 40 seconds. b) During whic

Gekata [30.6K]

Answer:

a) 0 metres

b) From time 0 s to 10 s , the car was accelerated. Its velocity accelerated from 0m/s to 20 m/s

c) 20 m/s

Explanation:

a) <em>Formula of displacement= velocity x time</em>

time=40 s

velocity =0 m/s

∴ displacement= 0 x 40 = 0 m

Magnitude of displacement is 0 m

b) The increase in velocity shows that there has been acceleration.

c) The average velocity of the car is = $\frac{0+40}{2\\}$ {initial velocity + final velocity}

= $\frac{40}{2}$

=20

Therefore, the magnitude of the average velocity of the car is 20 m/s
