Answer:
In my knowledge
Option B. Lava flowed from the moon
and I am pretty sure cause I have read about it and option B is the conclusion I came with lol :D
Answer:
The distance that the spring compresses is:
Explanation:
<u>Kinetic and Elastic Potential Energy</u>
The kinetic energy of an object of mass m traveling at a speed v is:
The elastic potential energy of a spring of constant k that compresses a distance x is:
The block of mass m is moving at a speed v when compresses a spring of constant k. The kinetic energy will eventually transform into elastic energy, but before that, both energies will be equal. It happens when:
Simplifying:
Dividing by k:
Taking square root:
The distance that the spring compresses is
Answer:
b i think
Explanation:
energy is friction, friction is heat
C. Electromagnetic waves do not always need a medium to travel.
Since they are transverse waves they do not need a material medium.
If you are talking about a scientific hypothesis, it essentially needs to be falsifiable, that is, that it can be proven wrong. Another requirement is for it to be testable, though under certain circumstances and definitions those two mean the same things. <span>
