Two sources emit beams of microwaves. The microwaves from source A have a frequency of 10 GHz, and the ones from source B have a frequency of 20 GHz. This is all we know about the two beams. Which of the following statements about these beams are correct? (There could be more than one correct choice.)
A) Beam B carries twice as many photons per second as beam A.
B) A photon in beam B has twice the energy of a photon in beam A.
C) The intensity of beam B is twice as great as the intensity of beam A.
D) A photon in beam B has the same energy as a photon in beam A.
E) None of the above statements are true.

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
