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:
Explanation:
The two examples of contact forces are frictional force and applied force. The two examples of noncontact forces are gravitational force and magnetic force.
Answer:
what is the question ? That is only a statement
Black and Whites were hungry and thirsty
(And don't forget that an object going around a curve at a constant speed is also accelerating.)
I believe there are two reasons:
1). The term is inadequately taught in the American public school system ... along with much of the rest of Science and Math in general.
2). The word became permanently and indelibly corrupted when the automotive industry decided to name the gas pedal the "accelerator".
