If several ball are thrown straight up with different initial speeds, the quantity that will hve the same value along their paths is their

a. initial momentum
b. maximum height
c. time travel
d. acceleration
e. none of the above

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

J. j. thomson’s experiment disproved the theory that an atom

What is the increase in density of a medium due to wave travel?
