Answer:
Explanation:
The wavelength is the distance between two adjacent wavefronts. ... If the wave crosses to the new medium at an angle (not 90 degrees), the change ...

Answer:
Josh is running at a speed of 9.09 yards per second.
Josh's velocity is 9.09 East.
Josh's force is 900 N.
Aaron Donald's force is 845 N.
Yes Josh scores the touchdown because he is faster and has more mass than Donald.
Explanation:
Josh scores the touchdown as he is heavier and faster than Donald.
Formulas are:
Force= mass x acceleration
Speed= distance divided by time.
Velocity= distance divided by time.
