A 2-kg bowling ball sits on top of a building that is 40 meters tall possess gravitational potential energy. It <span> is </span>energy<span> an object possesses because of its position in a </span>gravitational <span>field. We calculate as follows:

GPE = mgh = 2(9.8)(40) = 784 J</span>

The bowling ball is at rest, so it only has gravitational potential energy.

Ug = mgy
Ug = (2)(9.8)(40) = 784 J

A car traveled 112.0m in 24.500s, what was a car’s average speed?

kodGreya [7K]

Average speed of the car is 4.57 m/s

Explanation:

Speed is calculated by the rate of change of displacement.

It is given by the formula, Speed = Distance/Time

Here, distance = 112 m and time = 24.5 s

Speed of the car = 112/24.5 = 4.57 m/s

What factors determine the magnitude of the electric force between two particles ?

sattari [20]

Answer:

Force between two particles depends on the magnitude of charge on the particles and distance between them

Explanation:

We know that

According to coulomb's law electric force between two Particles is given by

$F=\frac{1}{4\pi \epsilon _0}\frac{Q_1Q_2}{R^2}=\frac{KQ_1Q_2}{R^2}$ , here K is constant $Q_1\ and\ Q_2\ charge\ on\ the\ particles$

R is the distance between the charge particles

So force between two particles depends on the magnitude of charge on the particles and distance between them
