Find the speed of the wave
A copper wire, whose cross-sectional area is 1.1 x 10-6 m2has a linear density of 7.0 x 10-3kg/m and is sturng between two walls. At the ambient temperature, transverse wave travels with a speed of 46 m/s on this wire. The coefficient of line is expansion for copper is 17 x 10-6(C)-1 and Young's modulus for copperis 1.1 x 1011 N/m2. What will be the speed of the wave when the temperature is lowered by 14 C? Ignore any change in the linear density caused by the change in temperature.
If the velocity of the box in problem 10 was 5.0 m/s at time zero, what will be its speed after 0.50 s? How far will it travel in that time interval?
the energy stored in the capacitor decreases with time as the capacitor discharges. After how many time constant is this stored energy one forth its initial value
A single-phase transformer has a voltage ratio of 6:1 and the h.v.winding is supplied at 540V. The secondary winding gives a full load current of 30A at a power factor of 0.8 l
