1 answer:
Answer:
F. Either B or C
Explanation:
The beat frequency is the difference of two frequencies of two waves.
Here, one wave has frequency 610 Hz and the beat frequency is 3 beats per second.
It is not mentioned which has a higher frequency. So, there are two possiblities.
or
Hence, the frequency of the other wave is 613 or 607.

<h2>Answer: B. Gravitational potential energy </h2>
Explanation:
<em>The gravitational potential energy is the energy that a body or object possesses, due to its position in a gravitational field. </em>
That is why this energy depends on the relative height of an object with respect to some point of reference and associated with the gravitational force.
In the case of the <u>Earth</u>, in which <u>the gravitational field is considered constant</u>, the value of the gravitational potential energy will be:
Where is the mass of the object,
the acceleration due gravity and
the height of the object.
As we can see, the value of is directly proportional to the height.
