I think that your answer should be D) the state should make use of satellites and radars because they detect when a storm is coming
∆S>_closed integral of dQ/T
There are many equations for different situations of entropy but this is a general one
Power = Work/Time
Convert 5 min to seconds and divide 2150J by that number.
Answer:
F = 5.33*10^-4N
Explanation:
to find the electrostatic force you use the Coulomb's law, given by the formula:

k: Coulomb's constant = 8.89*10^9 Nm^2/C^2
q_a: charge of A = 2.0*10^{-6}C
q_B: charge of B = -3.0*10^{-6}C
r: distance between the spheres = 10.0m
By replacing all these values you obtain:

hence, the forcebetween the spheres is about 5.33*10^-4N
