can you help me do this?
A thermoelectric-based power meter has a response time of 20 s and sensitivity (output voltage per unit incident power) of 90 mV/W. If the time response is reduced to 8 s by increasing the thermal conductance between the sensor element and heat sink, what will be the new sensitivity?

A laser beam has a power of 10 W of blue light that is horizontally polarized. It passes through a series of filters with axis of polarization at 0° w.r.t. the horizontal, 45° w.r.t. the horizontal, and 90° w.r.t. the horizontal. What is the power that emerges from these polarizers? Optic axis 2 = 45° Optic axis =90° Eof incoming light Optic axis 1=0° O 2.5 W Oow 01.25 W O 5W There is a magnetic...
