Answer:
4) C.mass
5) C. Potential Energy
Explanation:
4) Kinetic energy (KE) of an object is the energy that it possesses due to its motion. If a mass is in motion ,it has a kinetic energy .
By definition
what matters in Kinetic energy is the mass and the velocity only .
there fore the answer is
C.mass
5) Potential energy is the energy stored in an object, due to the object's position or arrangement.
By definition
in potential energy the height matters.higher the height , higher the energy
therefore the answer is
C.Potential Energy
A plane figure with at least three straight sides and angles, and typically five or more.Polygon-
Consecutive vertices-The endpoints of one side of a polygon.
diagonal of a polygon
A polygon with all the angles equal and all the sides equal.
regular polygon
Any closed figure bounded by three or more segments that only intersect at their endpoints. The segments are called the sides, and the endpoints are called the vertices of the polygon.
Plz mark me brainliest!
Hope this helps!
Answer:
Coin-shaped compartment that contains light-absorbing molecules - Thylakoid
Well, It rather depends on your definition of "machine." The normal physics set of simple machines - levers, pulleys, ramps all give you increased the force at the expense of reduced speed or increased the rate at the cost of reduced force. So, no - by definition a machine is an arrangement for multiplying one while paying the cost by reducing the other. You are looking at an example of the Conservation of Energy. One of the giant rules we are pretty sure cannot be violated.<span>

The sun is just one of the uncountable stars in the universe, as there are more than billions of galaxies containing billions of stars.
