I'm not sure if a figure or some choices go along with this, but the closer to the sea floor the diver is, the lower the potential energy
Answer:
Newtons first law
Explanation:
object in rest stays at rest
object in motion stays in motion
Answer:
6ms^-1
Explanation:
Given that the frequency difference is
( 563- 544) = 19
So alsoThe wavelength of each wave is = v/f = 344 /544
and there are 19 of this waves
So it is assumed that each motorcycle has moved 0.5 of this distance
in one second thus the speed of the motorcycles will be
=> 19/2 x 344/544 = 6.0 m/s
From my new perspective, the new intensity of the
light source has decreased by a factor of four.
