A measurement system can be modeled by the equation y F t + = 2 2 ( ) Initially, the output signal is steady at 75 volts. The input signal is then suddenly increased to 100 volts. (a) Determine the time constant and the sensitivity of the system. (b) Determine the response function.

Modern physics a photon emitted from an excited hydrogen atom has an energy of 3.02 electron volts. which electron energy-level transition would produce this photon? a. n=1 to n=6 b. n=2 to n=6 c. n=6 to n=1 d. n=6 to n=2 i chose b but the correct answer is d can someone tell me why? and what's the difference?
