There is not picture or anything what are the answer choices?
Answer:
the answer would be to conduct secret research
When a ball is at a particular height it possess potential energy which is given as,
The potential energy is converted into kinetic energy of the ball. According to conservation of energy,
which can be further given as,
Substitute the known values,
Thus, the kinetic energy of the ball is 0.140 J.
If this were to happen then the particle would be at the node (the point in the middle where the lines meet). Therefore, the particle will not move up or down because you can see the waves interfere destructively so there is no movement at the node.
answer. The particle will remain stationary due to interference.
Second hand:
1 rev per minute = (2π radians/minute) x (1 min/60sec) = π/30 rad/sec
Minute hand:
1 rev per hour = (2π radians/hour) x (1 hr/3600 sec) = π/1800 rad/sec
Hour hand:
1 rev per 12 hours = (2π rad/12 hr) x (1 hr/3600 sec) = π/21,600 rad/sec
As long as the clock is in good working order, and the hands are turning steadily at their normal rate, there is no angular acceleration.
