The answer would be 21.6 but rounded up it would be 22J.
To solve this problem it is necessary to apply the concepts concerning the conservation of both potential and thermodynamic energy of the body. That is to say that as the body has a loss of potential energy it is gained in the form of thermal energy on water. If the potential energy is defined as

Where,
m= mass
g = Gravitational acceleration
h = Height
And thermal energy is obtained as

Where,
= Change in Temperature
Specific Heat
m = Mass
We can equate this equation and rearrange to find the change at the Temperature, then


Our values are given as,
Specific Heat Water
Using energy conservation


Replacing,


Therefore the temperature increase in a 1kg sample of water is 1.89K
Answer:you can just look this up yknow?
Explanation:
Answer:
Color
Explanation:
Thus, for stars, considering them as “black bodies”, we can get an approximate figure for their temperature by measuring their dominant frequency (color). Technically scientists measure the brightness of the blue light and that of red light from the star, and from this they can calculate the temperature of the star.
Hello
We know that the water's kinetic energy upon leaving will be converted into potential energy as it is projected straight up. The maximum height attained by the water is 29.6m.
We know Kinetic Energy is
1/2 * m * v^2
And Potential energy is
m*g*h
Equating,
(m*v^2)/2 = m*g*h
The mass cancels out from each side, making an object's mass irrelevant when its Kinetic and Potential energies are interchanging.
v = sprt(2gh)
v = sqrt(2*9.81*29.6)
v = 24.1 m/s
