Answer:
rpm
Explanation:
Given that rotational kinetic energy = 
Mass of the fly wheel (m) = 19.7 kg
Radius of the fly wheel (r) = 0.351 m
Moment of inertia (I) = 
Rotational K.E is illustrated as 
Since 1 rpm = 
Acceleration means speeding up, slowing down, or changing direction. The graph doesn't show anything about direction, so we just have to examine it for speeding up or slowing down ... any change of speed.
The y-axis of this graph IS speed. So the height of a point on the line is speed. If the line is going up or down, then speed is changing.
Sections a, c, and d are all going up or down. Section b is the only one where speed is not changing. So we can't be sure about b, because we don't know if the track may be curving ... the graph can't tell us that. But a, c, and d are DEFINITELY showing acceleration.
Answer:
14 N
Explanation:
The tension in the second string is puling both the masses of 20 kg and 8 kg with acceleration of 0.5 m s⁻²
So tension in the second string = total mass x acceleration
= 28 x .5 = 14 N . Ans..
Basketball is played with two<span> teams, with </span>4 players<span> from each team on the court at one time. The maximum number of players on the bench differs by league. In international play, a maximum of </span>7 players<span> are allowed on the bench, resulting in a roster of </span>12 players<span>.

Answer:
The answer to your question is: F = 70 pounds
Explanation:
To calculate the net force, only substract the left value to the right value.
F = F right - F left
F = 100 p - 30 p
F = 70 pounds
