Find the charge on the capacitor in an LRC-series circuit at t = 0.04 s
when
L = 0.05 h,

R = 3 Ω,

C = 0.02 f,

E(t) = 0 V,

q(0) = 3 C,
and
i(0) = 0 A.

Determine the first time at which the charge on the capacitor is equal to zero. (Round your answer to four decimal places.)

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
