Answer:
Jupiter has an internal heat source.
Explanation:
It is believed that most of this heat is the residual (left over) heat from the time when formation of early Solar nebula took place. Jupiter absorbs energy from the Sun in the form of light and the coverts it into heat and later releases this heat in the form of thermal radiation.
It is recorded that Jupiter emits almost twice amount of energy from the amount which it receives from the sun. It is this internal source of energy and sunlight which provide energy to Jupiter's atmosphere.
However, this phenomenon of internal heat source is also seen in other celestial bodies as well such as Saturn, Neptune, Stars, etc.
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.
Answer:
Total energy of the object = mgh. As it falls, its potential energy will change into kinetic energy. If v is the velocity of the object at a given instant, the kinetic energy = 1/2mv2.
Explanation:
Answer:
hydrogen bond
Explanation:
Water has atom of oxygen and 2 atoms of hydrogen. The bond is formed between oxygen of one molecule and hydrogen of another molecule. This bond is called hydrogen bond.
The gravitational pull will reduce, because the moon is moving further away from the centre of the earth. In other words, the further an object is from the centre of the earth, the weaker the gravitational pull that will be exerted on it.
