A0.012 kg ping pong ball placed 1.8 m away from 0.3 kg billbard ball. calculate gravitational force between two objects

7.4 x 10^-14 N

Explanation:

m = 0.012 kg, M = 0.3 kg, r = 1.8 m

Let the gravitational force be F.

F = G M m / r^2

F = (6.67 x 10^-11 x 0.3 x 0.012) / (1.8)^2

F = 7.4 x 10^-14 N

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
