QUESTION:

Integrated Concepts

A \(160-\mu F\) capacitor charged to \(450 \mathrm{~V}\) is discharged through a \(31.2-k \Omega\) resistor.

(a) Find the time constant.

(b) Calculate the temperature increase of the resistor, given that its mass is \(2.50 \mathrm{~g}\) and its specific heat is \(1.67 \frac{\mathrm{kJ}}{\mathrm{kg} \cdot{ }^{\circ} \mathrm{C}}\), noting that most of the thermal energy is retained in the short time of the discharge.

(c) Calculate the new resistance, assuming it is pure carbon.

(d) Does this change in resistance seem significant?

The factor y in the Doppler formula (15.64), which can be ascribed to time dilation, means that even when 0 = 90 there is a Doppler shift. (In classical physics there is no Doppler shift when 6 = 90 and the source has zero velocity in the direction of the observer.) This transverse Doppler shift is t
