Answer:
mj = 53.3kg
Explanation:
Since both gravitational energies are the same:
Eb = Ej => mb*g*hb = mj*g*hj
Solving for mj:
mj = mb*hb/hj = 80*2.4/3.6
mj = 53.3kg
From the definition of the first Law of thermodynamics we know that heat flows from the hottest object to the coldest. What has a refrigerator inside is a refrigerant that is traveling through some heat exchangers, driven by pumps and that allows the exchange of heat between a 'Hot' tank and then transport it to a certain place, eject it and return to extract more heat. In this way the refrigerant removes heat from a hot region to a cold region and heat enters said hot region. Since the heat extracted is greater than that of the medium, the heat from the inside flows outward.
The correct answer is B.
destructive interference occurs when two or more waves combine to make a wave with a smaller amplitude C is your answer my friend :)
There are many other renewable sources to use such as hydro power, and wind power. All of these are renewable and safe to the environment. One reason solar power may not be used is because of it's cost.
Answer:
Explanation:
Given equation:
To solve the given equation:
Multiply both sides by T₀:
Add 100 to both sides:
Subtract 
from both sides:
Factor out the common term T₀:
Divide both sides by
