1. Name the rays A and B.
2. Which ray has more speed ( A or B ) in the glass medium ?
3. Which phenomenon is shown in the given diagram ?
4. Ray B is bending more than the ray A. What is the reason behind it ?
Answer:
According to the gravitational law of Isaac Newton, "the gravitational force between any two objects is proportional to the product of the objects’ masses and inversely proportional to the square of the separation between their centers".
Therefore gravitational constant is the proportionality constant used in Newton’s Law of Universal Gravitation, and is commonly denoted by G. It is expressed as:
F= Gm1m2/r2
Another scientist Cavendish was able to measure the gravitational force and the value of the proportionality constant. It is expressed as G = 6.673×10-11 N m2 kg-2.
B. Doldrums. I cant actually explain it i just know its the answer
Oceanic crust is *denser* than continental crust.
oceanic crust consists mostly of rock

A vacuum doesn't contain a medium.
Light, which is an electromagnetic
wave and doesn't require a medium,
will travel there. Sound, which is a
mechanical wave and requires a
medium, will not travel there.</span>
(You can see the light of the sun and other stars, which travels to us through
space. Astronauts can't hear the sound of each others' voices when they're
standing together on the moon because there's no medium between them,
so they have to use radio even to go only a few feet.)
