Which wave, A or B, has higher energy? A, because it has a higher amplitude
B, because it has a higher amplitude
A, because it has a lower amplitude
B, because it has a lower amplitude

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.

Give an example in which the electrical energy changes to light energy

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
