Because it takes power from the electricity to turn on so it heats up

A 0.200-kilogram ball A is traveling at a velocity of 2 meters/second. It hits a 1-kilogram stationary ball B. Which statement i

ioda

As we know that collision is elastic so we will have

$e = 1 = \frac{v_2 - v_1}{2 - 0}$

$v_2 - v_1 = 2 m/s$

also we can use momentum conservation

$P_{1i} + P_{2i} = P_{1f} + P_{2f}$

$0.200(2m/s) + 0 = 0.200 v_1 + 1v_2$

$0.4 = 0.2v_1 + v_2$

now from above two equations we will have

$1.2 v_1 = -1.6$

$v_1 = -1.33 m/s$

also we have

$v_2 = 0.66 m/s$

so both balls will separate after collision and move in opposite direction as the final velocities are opposite in sign

So correct answer will be

D. The balls separate and move in opposite directions.

Scientists experimenting with two charged objects of 2.56 x 10-6 C and 3.34 x 10-7 C displayed a repulsion of 2.26 x 10-3 N. How

Answer:

The objects were 1.8m apart.

Explanation:

We will start stating the Coulomb's Law. It says that:

$F_e=\frac{Kq_1q_2}{r^{2}}$

Where F_e is the electric force between the objects, q_1 and q_2 are the magnitude of the charge of the objects, r is the distance between them and K is the Coulomb's constant ( $K=8.9*10^{9} \frac{Nm^{2} }{C^{2} }$ in vacuum). Solving for the distance r we have:
