The following apply:
Sound is a LONGITUDINAL wave.
Sound is a PRESSURE wave.
Longitudinal waves are waves in which the displacement of the medium is in the same direction as or opposite direction to the direction of wave propagation. An example of longitudinal wave is sound wave. Sound wave is also considered as a pressure wave as the result of the presence of repeating patterns of high and low pressure regions moving through a medium.
Our sun is AVERAGE in every way among the known stars, including mass, age, size, temperature, etc. It doesn't stand out in any way.
Answer:
677 m
Explanation:
Using the definition of the sine of an angle, we can write
sin 14.1 = (height of mountain) / (slope length of mountain)
sin 14.1 = H / (2780 m) ---> H = (2780 m) x sin 14.1
= 677 m
Answer:
1) mass of the objects
2) distance between their centers
Answer:
The ball will take path 'c' after colliding with the bumper.
Explanation:
If the ball is made not to spin, then it will deflect along path b
From above, If the ball spin clockwise and the point of the ball is in contact with the edge of the table stops for a moment during the collision.
Due to the angular momentum of the ball, the ball would be forced to move towards the left. The rotational velocity will be initially downward because cue made the ball to rotate in the clockwise direction. For the ball to spin less there will be some torque acting on the ball which will cause acceleration in the counterclockwise direction.
The edge of the table produce the required acceleration. i.e a force have to be exerted by the edge of the table on the ball with a component to the left as viewed from the player's perspective.
Therefore, the ball will take path'c' after colliding with the bumper.
