PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!! Which wave has the smallest amplitude?
1 answer:
Answer: Option (1) is the correct answer.
Explanation:
The vertical distance between crest or trough from the origin or equilibrium point is known as amplitude of a wave.
In the given pictures, a wave that shows maximum height from the origin will have the maximum amplitude. Whereas the wave that shows minimum height from the origin will have the smallest amplitude.
Thus, we can conclude that waves shown in option 1 will have the smallest amplitude.

Answer:
The tension in the rope is 229.37 N.
Explanation:
Given:
Mass of the block is,
Coefficient of static friction is,
Angle of inclination is, °
Draw a free body diagram of the block.
From the free body diagram, consider the forces in the vertical direction perpendicular to inclined plane.
Forces acting are and normal
. Now, there is no motion in the direction perpendicular to the inclined plane. So,
Consider the direction along the inclined plane.
The forces acting along the plane are and frictional force,
, down the plane and tension,
, up the plane.
Now, as the block is at rest, so net force along the plane is also zero.
Therefore, the tension in the rope is 229.37 N.
