Increase the mass of the beanbag its gravitational potential energy will
1 answer:
The gravitational potential energy will increase
Explanation:
The gravitational potential energy (GPE) of an object is the energy possessed by the object due to its position in a gravitational field.
Near the Earth's surface, the GPE of an object is given by
where
m is the mass of the object
g is the acceleration of gravity
h is the heigth of the object above the ground
From the equation, we see that the GPE is directly proportional to the mass: therefore, if the mass increases, the GPE will increase as well.
So, for the beanbag in this problem, when its mass increases, the GPE will increase as well.

Explanation:
It is known that energy balance relation is as follows.
Also,
so,
According to the ideal gas equation,
Putting the values into the above equation as follows.
=
= 693.3 R
Now, we will convert the temperature into degree Fahrenheit as follows.
693.3 - 458.67
=
From table A-
= 0.240 Btu/lbm R and
= 0.171 Btu/lbm
Now, we will substitute the energy balance as follows.
=
= 59.3 Btu
Thus, we can conclude that final temperature of air is 59.3 Btu.
