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>
Electrical because without it, the hairdryer wouldn’t turn on. Thermal and sound are types of energy that are released after turning it on.
Answer:
1) W = 150 J
Explanation:
Work (W) is defined as the product of force F by the distance (d)the body travels due to this force.
W= F*d Formula ( 1)
The work is positive (W+) if the force has the same direction of movement of the object.
The work is negative (W-) if the force has the opposite direction of the movement of the object.
The component of the force that performs work must be parallel to the displacement.
Work done to lift the floor box to its final position
We apply the formula (1)
W= F*d
W = (100 N)*(1.5 m)
W = 150 J
The correct answer is Meteoroid!
Meteoroids are significantly smaller asteroids. .
A meteor is a Meteoroid passing through the atmosphere and leaving the visual trace that we are all familiar with.
A meteorite is the part of the meteoroid that actually reaches the Earth.
