Answer:
Mechanical energy = 145 Joules
Explanation:
Given the following data;
Kinetic energy = 115J
Gravitational Potential energy = 30J
To find the mechanical energy;
Mechanical energy = kinetic energy + gravitational potential energy
Substituting into the equation, we have
Mechanical energy = 115 + 30
<em>Mechanical energy = 145 Joules. </em>
Mechanical energy can be defined as the ability (capacity) to do work. The two (2) main types of mechanical energy are;
<em>a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.</em>
<em>b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.</em>

Answer:
8 (not including Pluto because its not a planet)
When a volcano erupts, the molten rock (or magma) that comes out of the Earth is called lava. Because lava is so hot (more than 1,100 degrees C, over 2,000 degrees F), it remains molten and flows across the ground until it cools and hardens into rock.

Answer: B, but not really...
Alternate Answer: Stars don't move, they are stationary in space.The Earth rotates around the sun and it appears that the sun and stars rotate around us, but they don't.
