Answer:
The moons of the outer planets are made of a mixture of ice and rock but our moon is made of only rock
Explanation:
When it comes to moon the elements silicon, iron & oxygen are classified as rocky materials and the elements carbon, nitrogen & Oxygen-Hydrogen compounds are classified as icy materials.
Our moon is primarily made of Silicon, aluminum, iron, calcium and iron.
Moons of outer planets are made of both icy materials and rocky materials.
AnswerAmontons's law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. ... If the gas volume is decreased, the container wall area decreases and the molecule-wall collision frequency increases, both of which increase the pressure exerted by the gas (Figure 1).:

Answer:
Momentum
Explanation:
-Conservation means that any quantity is kept constant.❌
-Force is product of mass and acceleration.❌
-Impulse is product of force and the period of action of the force.❌
-Momentum is the product of mass of a body and it's velocity.✔️
Answer:
a) One
Explanation:
In a uniform circular motion there must be a force acting to keep it in the circular track. This force can either be centripetal or a centrifugal force.
According to the Newton's first law of motion a particle continues to be in state of rest or in uniform motion until acted upon by an external force.
Here the term uniform motion need to be understood which refers to the uniform velocity of the particle in accordance to the vector laws.
