So, option (c) is correct.
1.The speed of something given in a direction, 2. The rate at which money changes hands within an economy
A motor spins upward the flywheel with a persistent torque
of 50N⋅m.
What time does it take the flywheel to get to the top speed?
From the equation:
Tj = J*dω/dt
you can get the two equations:
Δt1= J1*Δω/Tj = 240*125.66/50 = 603.17 sec
Δt2= J2*Δω/Tj = 120*125.66/50 = 301.58 sec
No but the sun could be a white dwarf stellar remnant.
