If a bat with a mass of 5 kg and acceleration of 2 m/s2 hits a ball whose mass is 0.5 kg in the forward direction, what is the reaction force of the ball on the bat?
1. 0 n, forward
2. 10 n, forward
3. 10 n, backward
4. 0.5 n, upward

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
