So far, I have not been able to run a mile in under 30 minutes.
That proves that I can't do it, but <span>that does not necessarily mean
its impossible. It </span>doesn't prove that nobody else can do it.
Nobody and nothing has ever traveled faster than the speed of light.
That doesn't prove that somebody or something that hasn't tried yet
can't do it. But discoveries in Physics, Quantum Mechanics, Cosmology,
and Relativity, over roughly the past 125 years, which explain and predict
almost everything seen in hundreds of experiments and thousands of
observations since then, do all agree that the speed of light is, let's say,
nature's "speed limit", and that no matter how hard you try, nothing and
nobody CAN travel faster.
Explanation:
Let i, j and k represents east, north and upward direction respectively.
Velocity due north, 
Velocity of the crosswind, 
Velocity of downdraft, 
(downward direction)
(a) Let v is the position vector that represents the velocity of the plane relative to the ground. It is given by :
(b) The speed of the plane relative to the ground can be calculated as :
v = 66 m/s
Hence, this is the required solution.
Answer:
Explanation:
Gravity is force of attraction between bodies that have masses. It is one of the most importance force in the universe that keeps it in an ordered form.
From what is obtainable from newtons law of universal gravitation, which states that "the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them";
we know that;
- Gravity is a force of attraction that pulls objects toward the earth's center.
- It increases with mass between two objects
- It decreases as the distance increases
