This is true. There is a downward force on the table that stabilizes the rock to stay there.
Answer:
three properties of intrinsic semiconductor
Motion is detected when an object changes its position with respect to a reference point. Coordinate system is basically used to represent motion. A coordinate system uses numbers or coordinates which represent position of the reference points on a two-dimensional or three-dimensional space. The trajectory of a point or line can be studied on a coordinate system which describes various aspects of motion like velocity, acceleration, distance, displacement etc. Coordinate system is important because it helps to choose a starting point and the direction (which will be positive).
Diagram A will result in the movement of the block to the left as a result of the forces.
<h3>What is Force?</h3>
This is referred to an influence which is capable of changing the motion of an object.
Diagram A has equal upward and downward force and left side which is 60N is higher than the right side which has 20N. The block will therefore move to the left.

To solve this problem we will apply the concept related to the amplitude and the Doppler effect. The difference between the maximum and minimum frequency detected by the microphone would be given by the mathematical function
Here,
= Source Frequency
= Speed of microphone
v = Speed sound
Maximum speed of the microphone is
Now the amplitude is
Here T means the Period, then
A= 0.2605m
Therefore the amplitude of the simple harmonic motion is 0.2605m
