Hire rubs an inflated balloon on his hair and his hair sticks to the balloon as he moves the balloon away from his head how does the electrical force change?

The options are missing and they are;

A) the electric force increases because the balloon loses its charge.

B) the electric force increases because the distance increases.

C) the electric force decreases because the distance increases.

D) the electric force decreases because his hair loses its charge.

Correct answer is option C - the electric force decreases because the distance increases.

Explanation:

The formula for electric force is;

F = k•q1•q2/r²

Where;

K is coulombs constant

q1 and q2 are particle charges

r is distance

So,looking at the formula given earlier, if we increase the distance, the denominator will increase and thus the Force will decrease.

So the correct option is option C

vapour or gas assuming atmospheriv pressure

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
