A rock is thrown with a force of 500 N and an acceleration is 75 m/s^2. What is its mass? (the arrow means exponent)

Explanation:

The mass of the rock can be found by using the formula

f is the force

a is the acceleration

From the question we have

We have the final answer as

Hope this helps you

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
