Answer:
<h2>1.4 m/s</h2>
Explanation:
The velocity can be found by using the formula
k is the kinetic energy
m is the mass
From the question we have
We have the final answer as
<h3>1.4 m/s</h3>
Hope this helps you
Answer:
t=2.348s
Explanation:
First we need to calculate the Potential Energy of a Tesla to reach the 100km/h
So we know that,
Here we can to calculate the time through,
Answer:
OD. The wave diffracted as it passed through the opening in the barrier.
Explanation:
A progressive wave (i.e waves in motion) has the capacity to bend around an obstacle on its path. This is one of the general properties of waves called diffraction. Others are: reflection, refraction, interference. Note that only transverse waves undergo polarization.
Diffraction of waves is the ability of waves to bend around an obstacle on its path during progression.
Thus, the bending of the part of waves as it passes through the barrier implies that the wave diffracted as it passed through the opening in the barrier.
