Technician A says that power is the rate that energy is stored. Technician B says that power refers to the rate that energy is t
Alex777 [14]

Answer:

C. Both technicians A and B

Explanation:

From the physical definition, power is defined as the rate of a body doing work. It is expressed as  

                                     P = w/t    watts

Where  

                       w - is the work done or the energy of the system in joules

                        t - time

The unit of power is represented in watts.

Whenever there is a rate of change of energy in the system, it accounts for the efficiency of the power of the system.

Hence, the statements of both technicians are correct.

A flywheel in the form of a uniformly thick disk of radius 1.33 m1.33 m has a mass of 70.6 kg70.6 kg and spins counterclockwise
ladessa [460]

Answer:

The constant torque required to stop the disk is 8.6 N-m in clockwise direction .

Explanation:

Let counterclockwise be positive direction and clockwise be negative direction .

Given

Radius of disk , r = 1.33 m

Mass of disc , m = 70.6 kg

Initial angular velocity , \omega_i =217 rpm

Final angular velocity , \omega_f =0\, rpm

Time taken to stop , t = 2.75 min

Let \alpha  be the angular acceleration

We know

\omega _f=\omega _i+\alpha t

=>0=217+2.75\alpha =>\alpha = -78.9\frac{rev}{min^{2}}

=>\alpha =-\frac{78.9\times 2\pi}{60\times 60}\frac{rad}{s^{2}}=-0.138 \frac{rad}{s^{2}}

Torque required to stop is given by

\tau =I\alpha

where  moment of inertia , I=\frac{mr^{2}}{2}=\frac{70.6\times 1.33^{2}}{2}kg.m^{2}=62.5 kg.m^{2}

=>\therefore \tau =-0.138\times 62.5\, N.m=-8.6\, N.m

Thus the constant torque required to stop the disk is 8.6 N-m in clockwise direction .
