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

A conductor of radius r, length and resistivity ρ has resistance r. what is the new resistance if it is stretched to 4 times its

max2010maxim [7]

The resistance of a conductor is given by
$R= \frac{\rho L}{A}$
where L is the length of the wire, $\rho$ the resistivity of the material and A the cross-sectional area.

We can see that if all the other quantities do not change, if the new length of the conductor is 4 times the original length: $L'=4 L$ , then the new resistance is also 4 times the original value:
$R'= \frac{\rho L'}{A}= \frac{\rho 4 L}{A}=4 \frac{\rho L}{A}=4 R$
