The main formula is
a=2d/t^2, so we can deduce that <span><span>t^2=2d / a, and t=sqrt(2d/a)
</span>for a=</span>2(m/s^2), d=10 meters,
so t=sqrt(2x10/2)=sqrt(10) s
Answer:
object with larger mass
Explanation:
the momentum of an object is directly proportional to its mass. larger mass = more momentum
Explanation:
Taking the incident light to be traveling in the + x-direction so that it is at normal incidence to the left side of the film(referred to as the "Front side"). This means the beam transmitted into the liquid is essentially as strong as the incident beam.
Almost all the light that is reflected off the back surface will get through the front surface. (But only 2.78% gets re-reflected off the the front surface back to the right) this means that there are two beams reflected to the - x-direction, one from the front surface and one from the back, and these beams are of almost equal intensity.
Hope this is helpful. Thanks
<span>A solid formed is described when its resistance is tightly secured, and when it refuses to change shapes. It is one of the four fundamental elements. The best answer would be: The atoms are packed together and cannot move around.</span>
