Answer #1

According to Wien's Law:

The wavelength at which the intensity of radiation is maximum is inversely proportional to the temperature of the body.

.

Answer: (D) To determine the peak wavelength of the blackbody radiation emitted by a person we would need to know the person's body temperature.

A) From mass, we can determine weight of the person.

B) From velocity, we can determine the kinetic energy of the person

C) From the electrical charge, we can determine how much electromagnetic effect it can put on another body.
