I would not agree with her since reflection and refraction happens only when waves hit an object. When, waves meet it is either it experiences constructive or destructive interference. Hope this answers the question. Have a nice day.
Larry's average speed is
(total distance) / (total time).
Speed = (80 km) / (60 min) = 80 km/hr .
Larry's average velocity is
(distance between start- and end- points),
in the direction from the start-point to the end-point.
Velocity = (40 km east) / (60 min) = 40 km/hr east .
Cm2 it is unit of area not volume
We have that the Force is mathematically given as
F=170.833N

Force </h3>
Question Parameters:
- The torque required to loosen a nut that is holding a flat tire in place on a car has a magnitude of 41 N · m,
- the end of a 24 cm-long wrench to <em>loosen </em>the nut
Generally the equation for the Force is mathematically given as
Therefore
F=41/0.24
F=170.833N

We are given the following values:
weight w = 240 lb = 1,067.52 N
energy E = 3,000 J
The formula for potential energy is:
E = w h
where h is the height the person has to climb, therefore:
h = 3000 / 1067.52
<span>h = 2.81 m</span>
<span>
</span>
<span>Therefore he has to climb 2.81 meters</span>
