Explanation:
it will collide then friction will slow it down
Answer:
Energy Ouput (Useful) / Total Energy Input = 4000 / 4800 = .833
E = 83% assuming 4800 is actually input to fan
Answer:
No
Explanation:
When one object heats another, the amount of heat transferred by the hotter object (
) to the colder object is equal to the amount of heat absorbed by the colder object (
):

The two amounts of heat can be written as:

where
is the mass of the hotter object
is the specific heat capacity of the hotter object
is the change in temperature of the hotter object
And

where
is the mass of the colder object
is the specific heat capacity of the colder object
is the change in temperature of the colder object
So we can write

or

We see that this ratio is not always equal to 1, since the two objects can have different masses and specific heat capacities: therefore, the changes in temperature are not equal.
Answer:
Explained below.
Explanation:
Nature is defined as all of the genes as well as hereditary factors that influence both the physical appearance and personality manifestations of any individual.
For example, a child could inherit certain physical traits and characters from his/her parents which in turn shapes the physique and personality of such an individual in the world.
