Answer:The higher up an object is the greater its gravitational potential energy. The larger the distance something falls through the greater the amount of GPE the object loses as it falls. As most of this GPE gets changed into kinetic energy, the higher up the object starts from the faster it will be falling when it hits the ground. So a change in gravitational potential energy depends on the height an object moves through.
Explanation: Lifting an apple up 1 metre is easier work than lifting an apple tree the same height. This is because a tree has more mass, so it needs to be given more gravitational potential energy to reach the same height.
Explanation:
Politics is the way that people living in groups make decisions. Politics is about making agreements between people so that they can live together in groups such as tribes, cities, or countries. ... The study of politics in universities is called political science, political studies, or public administration.
No. That's the description of the wave's 'frequency'.
Refraction of a wave is its behavior when it crosses
the boundary between two different media.
The answer is: 12.30 degrees.
To solve this problem you must apply the proccedure shown below:
1. You run 22 meters horizontally and then you climb a rope vertically for 4.8 meters.
2. So. let's call the angle 
, therefore, you must find it using 
, as following:
3. Substitute values and solve for the angle:
