Answer:
0.758 N
Explanation:
mass of ball, = 36 g = 0.036 kg
radius, r = 19 cm = 0.19 m
tangential velocity, v = 200 cm / s = 2 m /s
The tension is the string is equal to the centripetal force acting on the ball.
The centripetal force acting on the ball is given by
T = 0.758 N
Thus, the tension in the string is given by 0.758 N.
Answer:
44 ohm, 145 ohm
Explanation:
R = 44 ohm, L = 2.2 mH = 2.2 x 10^-3 H
At f = 60 Hz
XL = 2 π f L = 2 x 3.14 x 60 x 2.2 x 10^-3 = 0.82896 ohm
Impedance,
Z = 44 ohm
At f = 10 kHz = 10000 Hz
XL = 2 π f L = 2 x 3.14 x 10000 x 2.2 x 10^-3 = 138.16 ohm
Impedance,
Z =1 45 ohm
