your body emits radiation which peaks at 9.37 μm. What is your body heat? is the following

Explanation:

1.Human body temperature is about 310.15ºK . That puts the peak radiation in the infrared range. Human vision can see red light wavelengths as long as about 7,000 Angstroms. The infrared wavelengths are generally defined as being between 7,000 and 1,000,000 Angstroms

2.Wien's law formula

The equation describing Wien's law is very simple: λ max = b / T , ... λ max is the aforementioned peak wavelength of light, T is an absolute temperature of a black body, b = 2.8977729 mm*K is the Wien's displacement constant.

3.The Peak Wavelength is the wavelength where the spectrum reaches its highest intensity. This point is shown in the graph on the left and is labeled peak.

4. What is the temperature of a star with a wavelength of maximum light of 290 nm (recall: nm is the abbreviation for nanometers)? so T(K) = 2.9 × 106 λpeak( nm) K = 104K. According to Wien's Law λpeak = 2.9 × 106 T(K) nm = 2.9 × 106 106 nm = 2.9 nm.

Is a vector quantity that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
