Answer:
when it hit the moving bat
Explanation:
force equals mass times acceleration which means the moving bat will add more force to the ball.
Speed = distance / time
S= 40 000m / 5400s
S= 7.41m/s
Answer:
z1/z2
Explanation:
we have no quantum effects therefore we can make use of Maxwell Boltzmann distribution in the description of this system.
using the boltzman distribution the probability of finding a particle in energy state

we have
gi to be degeneration of the ith state
ei to be energy of ith state
summation

We have R to be equal to

Gold’s molar mass is about 196 while aluminum is about 27, thus 50cm of gold has more mass
They have the same velocity because their displacements (shortest line from point A to point B, which is a straight line) are the same and they meet at the same time.
