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.

Answer:
![418400\ \text{J}](https://tex.z-dn.net/?f=418400%5C%20%5Ctext%7BJ%7D)
Explanation:
m = Mass of water = 2 kg
c = Specific heat of water = ![4184\ \text{J/kg}^{\circ}\text{C}](https://tex.z-dn.net/?f=4184%5C%20%5Ctext%7BJ%2Fkg%7D%5E%7B%5Ccirc%7D%5Ctext%7BC%7D)
= Change in temperature = ![(50-0)^{\circ}\text{C}](https://tex.z-dn.net/?f=%2850-0%29%5E%7B%5Ccirc%7D%5Ctext%7BC%7D)
Change in thermal energy is given by
![Q=mc\Delta T\\\Rightarrow Q=2\times 4184\times (50-0)\\\Rightarrow Q=418400\ \text{J}](https://tex.z-dn.net/?f=Q%3Dmc%5CDelta%20T%5C%5C%5CRightarrow%20Q%3D2%5Ctimes%204184%5Ctimes%20%2850-0%29%5C%5C%5CRightarrow%20Q%3D418400%5C%20%5Ctext%7BJ%7D)

Answer:12.5 km
Explanation:
0.5=1/2
25 x 1/2 = 12.5 (25 ÷ 2 = 12.5)
The heat from the fire melting the wax helps close the circuit.
