All waves are known to undergo reflection or the bouncing off of an obstacle. Most people are very accustomed to the fact that light waves also undergo reflection. The reflection of light waves off of a mirrored surface results in the formation of an image.
Answer:
A. (-8,-5)
Explanation:
If you fill in A you get
-5 + 5 = 2(-8+ 8)
0 = 0
So this point is on the line
<u>Answer:</u> The initial temperature of the system comes out to be 147 °C
<u>Explanation:</u>
To calculate the initial temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,

where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:

Putting values in above equation, we get:

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:


Hence, the initial temperature of the system comes out to be 147 °C
