Answer:
A:
Explanation:
The earth rotates on it's axis every 24 hours not revolves.
Imagine rotation as a top spinning on the ground. revolving means if you tied a string to the top and spun it around your body in a circle. (hope this helps:)
The speed that the person needs to leave the ground will be 4.32m/s
From the question given,
Height = 95cm
Since the person leave the ground v = 0m/s
acceleration due to gravity g = 9.8m/s²
Using the equation of motion
v² = u² + 2as
a = -g (upward motion)
s = h (distance changes to height)
The equation will become:
0² = u² - 2gh
0² = u² - 2(9.8)(0.95)
u² = 18.62
u = √18.62
u = 4.32
Hence the speed that the person needs to leave the ground will be 4.32m/s

Nicolaus Copernicus was the one who brought astronomy out of the dark ages.
In one of his books "On the Revolutions of the Heavenly Bodies", he published the renowned line which declares his theory.
Nicolaus Copernicus, A polish astronomer put forward the theory that the is th Sun one that rests in the middle or center of the Universe and the planet Earth revolves around it on its axis every day.which was considered to be called the Heliocentric system.

Answer:
The answer is B. Without a college education, workers will actually lose money in the long run.
Explanation:
Just got it right on the assignment
Answer: Recall that
Work (W) = - e × ∆V
Where
Charge of electron= 1.6 × 10^ -19 c
And from the question we were given change in potential as = -0.0677V
Work = - (1.6 × 10^-19) × (-0.0677)
Work= 1.0832 × 10^-20J
Therefore the work done by the electric force when a sodium ion (charge = +e) moves from the outside to the inside is 1.0832×10^-20
