B. How much energy is emitted by the blackbody at all wavelengths in one hour?
Suppose that the sound level of a conversation is initially at an angry 70 dB and then drops to a soothing 50 dB. Assuming that the frequency of the sound is 500 Hz, determine the (c) initial and (d) final sound wave amplitudes.
An atomic nucleus of mass 288 u moving at 405m/s emits an alpha particle of mass 4.0 u in the direction of its velocity. If the remaining nucleus slows to 360m/s, what velocity does the alpha particle have when it is emitted.
