G is actually the universal gravitational constant.
6.674×10−11 m3⋅kg−1⋅s−2
This proportional to the product of the two objects masses and the inverse square of their distance.
This different from g which the local gravitational constant.
Answer:
9,000 N.
Explanation:
Workdone can be defined as the ability to do work. It is also the product of the force and the distance it is being moved.
Mathematically,
W = F * d
= 180,000/2
= 90,000 N.
Weight of the 10 cars = 90,000 N.
Weight of a car = 90000/10
= 9,000N.
The major source of cloud development is the water vapours from the surface of huge reservoirs like lakes. Vapours do not form when the water is cold. Water evaporates only when the surfave of the water is hot. And the vapours go into the atmosphere and condense to form clouds. Without vapours,there will be no clouds.
Answer:
For Total energy and momentum to be conserved, the minimum energy of the photons released is equal to twice the rest mass energy of an electron that is 
The annihilation of electron -positron cannot produce a single photon. It is prohibited by the law of conservation of energy and momentum.
