An object with a mass of 10kg accelerates 16 m/s2 when an unknown force is applied to it. What is the amount of force?
160 N
9.8 m/s2
165.8 kg
1.6 N

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 10 × 16

We have the final answer as

Hope this helps you

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

0.11 m/s and 0.28 m/s should be correct
