Answer:

1. 25%

2. You can move the skater higher up to increase the potential energy.

3. The kinetic energy increases because there is more motion.

Explanation:

1. If the total kinetic and potential energy is 100%, and we know that the kinetic energy is 75%, then we can find the potential by finding the missing value of this equation. Potential energy + kinetic energy =total energy.

? + 75%=100%

2. The higher an object is, the more potential energy it has because of the increase of its gravitational energy.

3. When an object is higher, there is more potential energy. As the skater goes down, the potential energy decreases which in turn increases the kinetic energy.

Answer:

D, the lithosphere. (CRUST AND UPPER MANTLE)

Explanation:

A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest. Plate thickness also varies greatly, ranging from less than 15 km for young oceanic lithosphere to about 200 km or more for ancient continental lithosphere (for example, the interior parts of North and South America).

Information found on:

An object is going 22 m/s and is 3 kg. find momentum
MAVERICK [17]
So what you wanna do is take your two givens. 22 and 3. Now you wanna take 22 and divide that by 3. And that gives you 7.33. Now if your answer HAS to be a whole number it'll be 66.

HELP I NEED THE ANSWER NOW
Setler79 [48]

Answer:

Speed of light

Explanation:

The famous Einstein's equation is:

E=mc^2

where

E is the energy

m is the mass

c=3\cdot 10^8 m/s is the speed of light

In this equation, Einstein summarized the following fact: mass can be converted into energy, and the amount of energy released in such a process is given by the equation.

An example of application of this equation is the nuclear fusion process. In a nuclear fusion, two lighter nuclei combine into a heavier nucleus. However, the mass of the heavier nucleus is slightly less than the sum of the masses of the two original nuclei: some of the mass of the original nuclei has been converted into energy, accorging to the previous equation.
