Charina says that when waves interact with an object, they will interfere with the object, and when waves interact with other wa
Fofino [41]
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 drives 20.0 km to the east from his house then 20.0 km west back to his house, takes 5.0 mins to find his wallet and leave
Scorpion4ik [409]

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 .

If 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, what minimum f
Marina86 [1]

We have that the Force  is mathematically given as

F=170.833N

<h3></h3><h3>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

F=\frac{T}{d}

Therefore

F=41/0.24

F=170.833N

A person who climbs up something (e.g., a hill, a ladder, the stairs) from the ground gains potential energy. a person's weight
zhannawk [14.2K]

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>
