Frequency x wavelength = ?

How have the competing explanations' experiments on atoms affected the development of the atomic model?

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.

Determine the maximum r-value of the polar equation r =3+3 cos 0
