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:
The value is
Explanation:
From the question we are told that
The amount of force a square meter of an aircraft wing should produce is
The air speed relative to the bottom of the wing is
The air level density of air is
Gnerally this force per square meter of an aircraft wing is mathematically represented as
Here u is the speed air need to go over the top surface to create the ideal lift
A is the area of a square meter i.e
So
=>
Answer:
A hypothesis
Explanation:
A hypothesis is an explanation for those facts and can expierimented on.
