Answer:
A. The amount of mass changes only slightly during a chemical
reaction.
If it's a mechanical wave, then its speed depends on the physical characteristics of the medium.
If it's an electromagnetic wave, then its speed depends on the
electrical characteristics of the medium.
Either way, the properties of the medium determine the wave speed.
You want to change the speed ? You have to change the properties
of the medium.
Answer:
Explanation:
The textbooks say that the maximum range for projectile motion (with no air resistance) is 45 degrees.
Anything times zero is zero
Change in position of object = Displacment
