The SI unit of mass is kilogram (kg)....
also displayed the effects of sound being an invisible force of our world. Sound are frequencies. Different frequencies shape matter differently as you’ve seen.
Now, the human ear can only hear frequencies to a certain extent. When you take a hearing test at the doctors, they test your hearing by playing different tones (frequencies) in your ear. As people get older they will not be able to hear higher frequencies.
In the same direction as the force
Answer:
962 rpm.
Explanation:
given,
angular acceleration = 190 rad/s²
initial angular speed = 0 rad/s
final angular speed = 7200 rpm
=
=
we need to calculate the revolution of disk after 10 s.
time taken to reach the final angular velocity
using equation of angular motion


t = 4 s
rotation of wheel in 4 s



θ = 1520 rad


now, revolution of the disk in next 6 s
angular velocity is constant


θ_f = 6044 rad
θ_f = 
revolution of the computer hard disk
θ_f = 962 rpm.
total revolution of the computer disk after 10 s is equal to 962 rpm.
Micah knows that a car had a change in velocity of 15 m/s.To determine acceleration ,Micah also needs the TIME of the total trip in seconds.
