Answer:
In this case we are dealing with the pythagorean theorm involving right angled triangles. This theorm states that a^2 + b^2 = c^2 which means the square of the hypotenuse (side c, opposite the right angle) is equal to the square of the remaining two sides.
In this case we will say that a = 3963 miles which is the radius of the earth. c is equal to the radius of the earth plus the additional altitude of the space station which is 250 miles; therefore, c = 4213 miles. We must now solve for the value b which is equal to how far an astronaut can see to the horizon.
(3963)^2 + b^2 = (4213)^2
b^2 = 2,044,000
b = 1430 miles.
The astronaut can see 1430 miles to the horizon.

Answer : Magnitude
Explanation :
In a value, the magnitude is represented by its units. It can be adopted by convention or by law.
Magnitude of any unit is used to measure the same kind of quantity.
For example: The unit of length which is a physical quantity is meter (m).
So, magnitude is correct answer.
A baseball traveling at 100 mph has more kinetic energy than a baseball traveling at 50 mph because the kinetic energy = 1/2 x mass x velocity. Since the baseballs should have the same mass, the velocity is what will determine which ball has more kinetic energy. Since the 100 mph baseball has a higher velocity than the 50 mph baseball, it has more kinetic energy.
Permeability is a measure of how fast a liquid can pass
through a layer of solid. In this case, the lesser the time, the more permeable
the solid is. Or the other way around, the bigger the time, the less permeable
the solid is. Therefore the answer in this problem is:
