A 20.0-µF capacitor is charged by a 150.0-V power supply, then disconnected from the power and connected in series with a 0.280

natali 33 [55]

Answer

given,

Capacitance of capacitor = 20.0-µF

Voltage = 150.0-V

inductance = 0.280 m H

a) the oscillation frequency of circuit

$f = \dfrac{1}{2\pi}\ sqrt{\dfrac{1}{LC}}$

$f = \dfrac{1}{2\pi}\ sqrt{\dfrac{1}{0.280 \times 10^{-3}\times 20 \times 10^{-6}}}$

f = 2126.9 Hz

b) $U = \dfrac{1}{2}CV^2$

$U = \dfrac{1}{2}(20\times 10^{-6})(150)^2$

U = 0.225 J

c)Current in the inductor

$V = L \dfrac{dI}{dt}$

$150 = 0.28 \times 10^{-3} \dfrac{dI}{dt}$

$\dfrac{dI}{dt} = 535714$

instantaneous rate of change of current is equal to 535714 A/s

In a shipping yard, a crane operator attaches a cable to a 1,400 kg shipping container and then uses the crane to lift the conta

Molodets [167]

Answer:

Explanation:

Given

mass of crane $m=1400\ kg$

distance moved $d=40\ m$

Since it is moving with a constant velocity therefore net force on it is zero

Tension force=weight

T=mg

Work done by Tension T is

$W_T=T\cdot d$

$W_T=1400\times 9.8\cdot 40$

$W_T=548.8\ KJ$

Work done by Gravity will be equal in magnitude but opposite in sign and can be obtained by work energy theorem which states that change in kinetic energy of object is equal to work done by all the forces

$W_T+W_g=0$

$W_g=-548.8\ KJ$
