A Sodium atom(mass=3.84 *10^-26kg) has its velocity increased from 100 to 101 by a 589-nm photon and the question is approximately how many photons are needed to hit each atom in order to produce the desired velocity boost. It's a Quantum Physics question if that helps.
An electron is initially moving at a speed of 1740 m/s directly toward a long wire that has 2.00 A of current flowing through it. What are the direction and amount of the force
If the acceleration ü(t) of the ground in Example is a single sine pulse of amplitude ao and duration t1' as shown in Figure.
Give two examples that could demonstrate the principle of crosscutting relationships. State how much time is represented by an unconformity. What is meant by correlation? How do index fossils aid correlation?
