Answer:
Explanation:
Heat is probably the easiest energy you can use to change your physical state. The atoms in a liquid have more energy than the atoms in a solid. There is a special temperature for every substance called the melting point.They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. EXAMPLE: Solid ice melting into liquid
Answer: 0.0187 times the force between Sun and Earth.
The gravitational force between two massive bodies is directly proportional to their masses and inversely proportional to the square of distance between them.
where G is the gravitational constant.
Let,
The mass of the Sun be 
The mass of the Earth be
The mass of the Neptune be
The Distance between Sun and Earth be 
The Distance between Sun and Neptune be 
It is given that the mass of Neptune is 17 times mass of Earth.
The distance of Neptune from Sun is 30.1 times the distance of Earth from Sun.
The Force between Earth and Sun is 
The Force between Neptune and Sun:
(2) impulse is a vector quantity. Energy has no direction, nor does power. Work is a dot product of vector quantities, which makes it a scalar.
Answer:
According to the Big Bang Theory, the density and temperature of the Universe is <u>lower</u> now than in the past.
