Force is the ability to cause masses to accelerate.
Without force, you could not make stuff accelerate.
If something was moving, you could not make it speed up, slow down, stop, or go in a different direction.
If a thing was not moving, you could not make it move at all.

Answer:
Option "D" is the correct answer to the following question.
Explanation:
According to The law of conservation of mass, in a chemical reaction mass neither created nor destroyed.
So,
Total product = Mass of magnesium + Mass of oxygen
Total product = 40 gram + 40 gram
Total product = 80 gram
Therefore, option "D" is the correct answer
Answer:
A. an increase in the height of the sound wave
Explanation:
Volume of the sound is measured by its intensity
So here we know that
intensity is directly depends on the square of the amplitude of the sound wave
so here as intensity depends on the loudness of the sound given as
so here as the loudness of sound will increase then the intensity will increase and hence the amplitude of the sound will also increase
So correct answer will be
A. an increase in the height of the sound wave
Motion is always relative to something.
-- Relative to the moon, an airplane is ALWAYS in motion.
-- Relative to the ground, an airplane is in motion when it's taxiing or flying.
-- Relative to a bag of peanuts in its own galley, an airplane is NEVER in motion.
