Answer:
<em>126.01 rad/s^2</em>
<em></em>
Explanation:
since it starts from rest, initial angular speed ω' = 0 rad/s
angular speed N = 477 rev/min
angular speed in rad/s ω = 
= 
= 49.95 rad/s
angular displacement ∅ = 1.5758 rev
angular displacement in rad/s = 
= 2 x 3.142 x 1.5758 = 9.9 rad
angular acceleration 
= ?
using the equation of angular motion
ω^2 = ω'^2 + 2∅
imputing values, we have
2495 = 19.8
= 2495/19.8 = <em>126.01 rad/s^2</em>
Answer:
they store information
Explanation:
Information are encoded on the magnetic part of a hard drive and the strip of a credit card.
- On the drive, series of magnetic fields are used to encode information.
- The data is stored in form of zeros and ones.
- A credit card has a magnetic strip where information is encoded.
- The stripe provides a readability function for electronic devices.
