Answer:
longer wavelength and lower frequency
shorter wavelength and greater frequency
Explanation:
f = v/l
l = wavelength
v = speed of wave
f = frequency
Answer:
is that a really questions
Answer:
Explanation:
The forces compare together as a result of the fact that the force exerted by that of the ball and the force exerted by that of the wall both have the same magnitude.
I'm sorry if this is wrong but I think it's 2.5 net
Answer:
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
Explanation:
As we know that average velocity is defined as the ratio of change in position and the time interval of the object
It is given as

so we will have
= displacement
= time interval
the direction is this average velocity is always along the direction of the displacement
so correct answer will be
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
