Answer:
hen dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance.
Explanation:
<span>The correct option is: (A) Transverse Wave
Explanation:
Transverse wave is a wave in which the medium vibrates at right angles to the direction of its propagation.
In this case, consider the crowd as the medium and the perceived motion of the wave as the propagation. When the crowd moves up and down, the perceived wave be either from left to right or right to left. In either case, the crowd movement is perpendicular to the propagation of the wave. Imagine the crowd's up-down movement along y-axis and the perceived propagation of the wave along x-axis. Both axes are perpendicular to each other. Hence, the correct option is (A) Transverse wave.</span>
Answer:
0.000234 seconds
Explanation:
Since the row is 0.15m, its radius of rotation must be 0.15 / 2 = 0.075 m
We can start by calculating the angular speed of the rod:
Since one revolution equals to 2π rad. The speed in revolution per second must be
26800 / 2π = 4265 revolution/s
The number of seconds per revolution, or period, is the inverse:
1/4265 = 0.000234 seconds
