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.
Answer:
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
If 
and 
are perpendicular, then their dot product is zero. This means
Solving for n is trivial; it follows that n = 3.
In pounds your answer is 15.4324 or 15.4
Answer:
183.75641 Joules
Explanation:
F = Force of the vacuum cleaner = 84.5 N
s = Displacement of the vacuum cleaner = 2.62 m
= Angle the force makes with the horizontal = 33.9°
Work done is given by
The work done by the force of the vacuum cleaner is 183.75641 Joules
All except B are examples of force
