Explanation:
The inner part of earth is mainly of two parts
- Mantal
- Core
Mantal and core both consists of Hot magmas .
So volcanism is required
If it isn't enough energy to make the jump from 1 energy level to the next energy level, then it will go no where
Answer:
From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star.
Answer:
It also plays a key role in vision. As light enters your eye, it gets refracted, or bent, by the cornea's curved edge. This helps determine how well your eye can focus on objects close-up and far away. If your cornea is damaged by disease, infection, or an injury, the resulting scars can affect your vision.
Answer: Fourth option. It increased by a factor of 3.
Solution:
m1=1.0 kg
Cylinder's gravitational potential energy: Ep=m*g*h
Ep1=(1.0 kg)*g*h
Ep1=g*h
m2=3.0 kg
Ep2=(3.0 kg)*g*h
Ep2=3*g*h
Replacing g*h by Ep1 in the equation above:
Ep2=3*Ep1
Then, the cylinder's gravitational potential energy increased by a factor of 3.
