Planets orbit the sun in the paths which are known as elliptical orbit. Each planet has its own orbit around the sun and direction in which all the planets orbit around the sun are the same. These orbits were well explained by the astronomer Kepler. The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.
Answer:
It stays the same.
Explanation:
Entropy of a system either increases or remains constant in any process, it never decreases.
'The principle of superposition states that when two disturbance occupy the same space at the same time the resulting disturbance is the sum of two disturbances.'
Explanation:
if two pulses are moving towards each other in the same medium and are not disturb by any external force they will approach each other and the point which will be the the sum of their individual displacement or more precisely the point of superposition of both pulses either constructive or destructive depending on the conditions given
Answer:
Magnets have two poles, called north and south. The like poles are attracted to unlike poles, but like poles repel each other. For example, the north pole of one magnet is attracted to the south pole of another. ... To make objects move with a magnet attach a piece of metal, or another magnet, to it.
Answer: 13.6 N
Explanation:
The equation of motion for the rabbit is:
(1)
Where:
is the distance traveled by the rabbit
is the rabbit's initial velocity, assuming it started from rest
is the time
is the acceleration
Isolating :
(2)
(3)
(4)
On the other hand, the force 
is given by:
(5)
Where 
is the mass of the rabbit
Substituting (4) in (5):
(6)
Finally:
