Two particles are moving toward one another. Both of the
particles have a strong positive charge. As they move toward
one another, how will the electric force between the two
particles change?
A. The electric force will remain repulsive
and decrease in strength.
O

B. The electric force will remain repulsive
and increase in strength.
C. The electric force will become attractive
and decrease in strength.
D. The electric force will become attractive
and increase in strength.

Amass has an acceleration of 10- 2t. what is its velocity and displacement if it started at x- 4m and the initial velocity was 8m/s? at what time does it have 0 velocity? graph all graphs.

The force will determine the acceleration.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
