If you are pushing the coin across the table at a constant rate, the friction of the table and the horizontal force of your hand pushing are equal, and the coin itself moves at a constant rate. If you push a coin and let it go, there is no horizontal force keeping the coin going. Friction slows the coin to a stop. In both cases, the gravitational downward pull of Earth is equally but oppositely resisted by the upward push of table on the coin.
The answer is oil and water. If you want I could give you the reason too
The correct answer is C) the focus
Given:
The number of vibrations of the tuning fork is,
in,
To find:
The frequency of the fork
Explanation:
The frequency is the number of vibrations in 1 second
The frequency for the given fork is,
Hence, the frequency is 148 Hz.
