Point of Aries is a celestial body which can be used to measure sidereal day.
<h3>What is a
sidereal day?</h3>
A sidereal day can be defined as an amount of time that it takes planet Earth to rotate once about its axis relative to the stars, so that distant stars appear within the same position in the sky.
Based on astronomical information and records, Point of Aries is a celestial body which can be used to measure sidereal day because it's the amount of time between two (2) consecutive transits of the First Point of Aries.

The range of force exerted at the end of the rope is 285.7 N to 1,000 N.
<h3>Net horizontal force of the cylinder</h3>
The net horizontal force of the cylinder when it is at equilibrium position is determined by applying Newton's second law of motion.
∑F = 0
F - μFn = 0
F - 0.2(5,000) = 0
F - 1,000 = 0
F = 1,000 N
The strength of the applied force increases as the number of turns of the rope increases.
minimum force = total force/number of turns of rope
minimum force = 1,000/3.5
minimum force = 285.7 N
Thus, the range of force exerted at the end of the rope is 285.7 N to 1,000 N.

The answer should be A because it’s frequency of a sound per second
Infrared rays are used in many forms of thermal technology. This is also used in weather reports to find the temperature of the surrounding areas.
When a ray of light strikes a plane mirror the light of the ray it reflects off from the mirror. reflection is a change in direction from the light ray.
