<span>Orbital radius would decrease because the gravitational pull would increase.</span>
The density will always be the same.
Answer:
The answer is "1557 meters".
Explanation:
speed of sound in (
)

At position of maximum height we know that the vertical component of its velocity will become zero
so the object will have only horizontal component of velocity
so at that instant the motion of object is along x direction
while if we check the acceleration of object then it is due to gravity
so the acceleration of object is vertically downwards
so it is along y axis
so here these two physical quantities are perpendicular to each other
so correct answer would be
<em>C)At the maximum height, the velocity and acceleration vectors are perpendicular to each other. </em>
The law of conservation of energy states that the energy cannot be created or destroyed, either it is transferred from one object to another.
Explanation:
The principle of conservation of energy is the energy is not created or destroyed it is only moved from one place to another.
There are various examples to explain the conservation of energy. some of them are explained here.
- If the moving car hits the parking car and that makes the parked car to move, at this state the energy is transferred from the moving car to the parked car.
- If you are pushing a book across the table, then the energy from your moving arm is transferred from your body to the book and that causes book to move.
- The another example for conservation of energy is A dog is running towards the tree and it gets hit to it. In this case the energy is transferred from moving dog to the tree, and causes the tree to move.
