B Quartz. Will be your answer of thia
Answer:
677 m
Explanation:
Using the definition of the sine of an angle, we can write
sin 14.1 = (height of mountain) / (slope length of mountain)
sin 14.1 = H / (2780 m) ---> H = (2780 m) x sin 14.1
= 677 m

1. the downward force is the force of gravity.
2. The upward force exerted is the Normal reaction from the floor.

p=mv
where p=momentum, m=mass and v=velocity.
Hence momentum is the combination of mass and velocity.

Geothermal energy.
Electromagnetic energy originates at the sun (think UV rays; they are part of the electromagnetic spectrum). Electrical energy technically can be anywhere, as long as there are positive and negative charges. Mechanical energy is like a generator or an engine; there is always something working to get things done/made.
I hope this answer and these explanations helped!
