The net torque is 0.4962 N m
Explanation:
please look at the solution in the attached Word file
Try and multiply A only and leave B and X alone (constant) try a number like 2
Answer:
IV. j1.06, capacitive
Explanation:
V(t) = 15cos( 200πt + 65 )
Irms = 10 A .
current leads by 90 degree.
reactance of the load .
Imax = Irms x √2
= 10 x √2
= 14.14 A
Now, Imax = Vmax / reactance
reactance = Vmax / Imax
= 15 / 14.14
= 1.06 ohm
Since current leads the voltage therefore , it must contain capacitance .
the load is capacitative. .
Wave Speed = wavelength x frequency
