A capacitor and a coil are connected in series across a 50 Hz variable ac supply of 234.6515.510 V. A voltage drop of vL(t) = 360 sin (ωt + 300

) V is measured across the

coil. The current flowing in the coil is 14.4 A at a power factor of 0.9063.

1.1.1 Determine the current drawn from the supply. (4)

1.1.2 Calculate the voltage drop across the capacitor. (2)

1.1.3 Calculate the capacitance of the capacitor.

Fluids at rest possess no flow energy. a)- true b)- false

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?
