Hi there!
Recall the equation for gravitational potential energy:
U = GPE (J)
m = mass (48 kg)
g = acceleration due to gravity (9.8 m/s²)
h = height (21 m)
Plug in the givens and solve.
Answer:
Heat capacity is the ratio of the amount of heat energy transferred to an object to the resulting increase in its temperature. Molar heat capacity is a measure of the amount of heat necessary to raise the temperature of one mole of a pure substance by one degree K.

Answer:
The answer is the Earth is tilted as the Earth makes its journey for the year around the Sun.
In general the earth is tilted at angle of 23.5 degrees from vertical axis. So that the Earth always pointing to one side as it revolves around the Sun. This causes varying amounts of Sun light around the Earth during the years gives us seasons.
So here we conclude that the axis of the Earth is most important thing, why the seasons occur.
Tilt:
Whenever the Earth lean towards the Sun, summer season occurs and lean away from the Sun winter season occurs. In between these two spring and Autumn occurs.

Answer:
$6.68
Explanation:
The current running through the device would be its outlet voltage divided by the resistance:
I = U/R = 115 / 11.4 = 10.09 A
The power generated by this device is the product of its current and voltage
P = IU = 10.09 * 115 = 1160 W or 1.16 kW
If running this device for 36 hours then the total energy it would consume is
E = Pt = 1.16 * 36 = 41.76 kWh
Therefore the total cost of electrical energy is
C = Ec = 41.76*0.16 = $6.68
