The disk's average angular speed during those 5 seconds was
(1/2) (100 + 300) rad/s = 200 rad/sec
Spinning for 5 sec at an average angular speed of 200 rad/s, the disk turned
(200 rad/s) x (5 s) = <em>1,000 radians</em>
(That's 500/pi revolutions = roughly 159.2 revolutions.)
Answer:
Explanation:
False
When two waves overlap or superimpose over each other then they either undergo Constructive or destructive interference.
waves are the disturbance created by a force and add up to gives constructive interference when they are in the same line i.e. in the same phase.
When these disturbances are in the opposite phase then they superimpose to give destructive interference where the amplitude of the resulting wave will be much smaller as compared to original waves.
Answer:
Yes , insulation has no role
Answer:
Net Force = 0
Explanation:
Causes objects to accelerate. Balanced Forces. Two equal forces push in opposite direction causing no change in motion causing net force = 0.
