Which correctly describes some of the motion of the bus?

The speed is increasing at 16-21 seconds; decreasing at 10-13 seconds; and is constant at 5-10 seconds.

The speed is increasing from 1-6; decreasing from 16-20; and is constant at 20-25 seconds.

The bus is moving forward from points O-A; stopped from points A-B; and moving back from points B-C.

Potential energy is constant and kinetic energy is increasing.

Potential and Kinetic energy are both increasing.

Kinetic energy is decreasing and potential energy is increasing.

What causes the tennis ball's change of motion?

The force of gravity causes it to change velocity (speed and direction).

Action reaction force pairs cause the ball to slow down as it drops.

The force of friction changes the direction of the ball.

Inertia decreases on the way up and increases on the way down.

Three blocks are the same exact size. However, one is more dense than the other two. Why is it more dense?

It has more mass than the other two.

It has more volume than the other two.

The color affects the overall density.

2Na + Cl 2 -----> 2NaCl In this reaction, the mass of the 2NaCl

is equal to the mass of 2Na plus Cl 2

is greater than the mass of 2Na plus Cl 2

is less than the mass of 2Na plus Cl 2
