I think the correct answer is C.
Answer:
Only 9% weaker
Explanation:
Because this is where most stuff that people do in space takes place. So, um, here we're at a radius of the earth plus 300 kilometers. You may already be seeing why this isn't going to have much effect if this were except the 6.68 times, 10 to the sixth meters. And so the value of Gout here. You know, Newton's gravitational constant times, the mass of the Earth divided by R squared for the location we're looking at. And so this works out to be 8.924 meters per second squared, which is certainly less than it is at the surface of the earth. However, this is only 9% less than acceleration for gravity at the surface. So the decrease in the gravity gravitational acceleration of nine percent not really going toe produces a sensation of weightlessness.
A. The answer is a because i had did research
Answer:
Types of Mechanical Energy
There are two types of energy: potential and kinetic.
Potential energy is energy that is stored in an object due to its position. This type of energy is not in use but is available to do work. For example, the book possesses potential energy when it is stationary on the top of the bookshelf.
Ep=m*g*h (m - mass, g - gravitaional acceleration (Earth mean value g=9, 81 m/(s2), h - height from the zero or referent level) s2=s*s
Kinetic energy is energy that is possessed by an object due to its motion. For example, if the book were to fall off the shelf, it would possess kinetic energy as it fell. All energy is either potential or kinetic.
Ek=(m*v2)/2 v2=v*v
The law of the conservation of energy states that energy is neither created nor destroyed. Instead, it is simply transferred from one type of energy to another, or from one form of energy to another. The difference between mechanical energy and kinetic energy is that kinetic energy is a type of energy, while mechanical energy is a form of energy.
