A non-sinusoidal voltage is v(t) = 5 + 10 * sin(2π * 50t + 30 ) 15sin(4π 0t 45 ) . o + * 5 + o This voltage is connected to the load which is a serial connection of a 10Ω resistor and a 10mH inductance. Determine: a) the power absorbed by the load, and b) Drive an expression for the load

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Ahe-xe mixture containing a 0.75 mole fraction of helium is used for cooling electronics in an avionics application. at a temperature of 300 k and atmospheric pressure, calculate the mass fraction of helium and the mass density, molar concentration and molecular weight of the mixture. if the cooling capacity is 10 l, what is the mass of the coolant?

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?
