Answer:
it's C (this is not a guess)
That was Tycho Brahe, and I thought it was actually more years than that.
The time of motion of the 5 kg object will be the same as 1 kg since both objects are dropped from the same height.
The given parameters;
<em>Mass of the first object, m1 = 1 kg</em>
<em>Mass of the second object, m2 = 5 kg</em>
The final velocity of the objects during the downward motion is calculated as follows;

The time of motion of the object from the given height is calculated as;

The time of motion of each object is independent of mass of the object.
Thus, the time of motion of the 5 kg object will be the same as 1 kg since both objects are dropped from the same height.

Answer:
The problem occurs with all spherical mirrors.
Spherical mirrors are practical up to about inches in diameter.
Reflecting telescopes use spherical mirrors for apertures up to about 4 ".
Larger aperture telescopes use parabolic mirrors to obtain sharp focus.
The power in every scenario is the same. Power is the measurement of the energy transfer over time.
<h3>
What is power?</h3>
Power is the measurement of the energy transfer over time. It can be calculated by the formula,

Where,
- power
- work
- time
In scenario A,

In scenario B,

In scenario B,

Therefore, the power in every scenario is the same.
