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:
volt ÷ ampere
Explanation:
The mathematical form of Ohms law is given by :
V = IR
Where V is voltage
I is current
R is resistance
The unit of voltage is volt and that of current is ampere
Unit of resistance :
So, volt ÷ ampere is the same as the unit of resistance. Hence, the correct option is (a).
Answer:
Force due to tension
Explanation:
Usually Ft, or F, denotes force due to tension or tension force. An example of tension force would be if you were pulling an object on a string - the tension force is present within the string and causes the string not to break.
