The three eons of precambrian time i.e hadean eon ,Archean eon and proyerozoic eon change earth's surface during Precambrian time.
547 kilometres, or 340 miles
Average speed = (total distance covered) / (time to cover the distance)
Ian's total distance = (2km + 0.5km + 2.5km) = 5 km
Ian's total time = 3 hours
Average speed = (5km) / (3 hours)
Average speed = 1.66 km/hr
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
Your basically breaking the sound beerier <span />
