A resistor R = 1 k Ohm an inductor L = 1 mH and a capacitor C = 1 mu Fare used in a circuit which is driven by a voltage source vs (t) = 10 sin (10 5 t + 45 degree) (warning: note the input is a sine function not a cosine function. What is the phasor corresponding to the voltage source? Express it in the polar form A < B and write your answer as "A B" without the quotation marks.

On a average work day more than work place firs are reorted

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
