3. While taking off from an aircraft carrier, a jet starting from rest accelerates uniformly to a final speed of 40. meters per second on a runway that is 70. meters long. What is the magnitude of the acceleration of the jet?
Let's first determine what we are given. We have initial speed = 0 since the jet starts at rest. We also have a final speed of 40 m/s. We have distance of 70 meters...
A photon with an energy of 1.33 × 10−21 joule has a frequency of
(1) 5.02 × 10^13 Hz
(2) 2.01 × 10^12 Hz
(3) 8.82 × 10^14 Hz
(4) 5.30 × 10^34 Hz
Answer and Explanation:
A photon is a particle of light. The formula for the energy of the photon can be found in the Physics Reference Table. It is Ephoton = hf where h is the plank's constant that can be found in reference table as...
