Answer:

Momentum

Explanation:

The property of a moving object having mass m and moving with velocity v is called its momentum. It is given by the mathematical form as follows :

$p=m\times v$

It is a vector quantity. Its SI unit of kg-m/s.

What speed would a fly with the mass of 0.55 g need in order to have the same kinetic energy as the automobile in the term 19

larisa86 [58]

The question does not provide enough information to complete the answer, so I'll assume the needed data to help you to solve your own problem

Answer:

The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile

Explanation:

Kinetic Energy

Is the capacity of a body to do work due to its speed and is computed by

$\displaystyle K=\frac{mv^2}{2}$

We are not given enough data to compare the kinetic energy of the fly with that of the automobile. We'll assume the following characteristics:

$m_a=500\ kg$

$v_a=10\ m/s$

So its kinetic energy is

$\displaystyle K_a=\frac{(500)10^2}{2}$

$\displaystyle K_a=25,000\ J$

The mass of the fly is

$m_f=0.55\ gr=0.00055\ kg$

To have the same kinetic as the automobile:

$\displaystyle \frac{m_fv_f^2}{2}=25,000$

Solving for $v_f$

$\displaystyle v_f=\sqrt{\frac{2(25,000))}{m_f}}$

$\displaystyle v_f=\sqrt{\frac{50,000}{0.00055}}$

$v_f=9,534.6\ m/s$

The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile

What is the acceleration aaa of the refrigerator 4 ss after the person begins pushing on it with a force of 400 NN

ruslelena [56]

Answer:

2 ms^2

Explanation:

Given that the mass of the refrigerator is 200Kg

The net force acting on the refrigerator is 400N

The time takes is 4s

From Newtons's second law of motion;

F =ma

a = F/m

a = 400/200

a = 2 ms^2

This is a constant acceleration

How does a crowbar work?

mylen [45]

It works by you putting leverage on one side makes more force go to the other side so if you put a crowbar in between a door and you push on one side the other will push the opposite side with more force

If the atmosphere is like a greenhouse, what parts of it function as the glass

prohojiy [21]

The ozone layer is like the glass. the light from the sun enters the atmosphere and when the heat bounces back it is hard to escape the ozone layer therefore the earth's temperature rises
