i just did the quiz an got it right
Answer:

Explanation:
From conservation of energy states that

I believe it is, since the heat causes the water to evaporate and cause condensation,
Answer:
The value of d is 20.4 m.
(C) is correct option.
Explanation:
Given that,
Initial velocity = 20 m/s
Final velocity = 0
We need to calculate the time
Using equation of motion

Where, u = Initial velocity
v = Final velocity
Put the value into the formula


We need to calculate the distance
Using equation of motion



Hence, The value of d is 20.4 m.
That's the 'electrostatic' force.
