You could use the formula
W=Fd
F(force)=20N
D(distance/displacement) =15m
W=(20N)(15m)
W= 300 J
Answer:
<h3>The answer is 19,800 J</h3>
Explanation:
The work done by an object can be found by using the formula
<h3>workdone = force × distance</h3>
From the question
force = 120 N
distance = 165 m
We have
work done = 120 × 165
We have the final answer as
<h3>19,800 J</h3>

Answer:
V = - 2[m/s]
Explanation:
This is a classic problem of relative velocities, in order to solve it we must understand each of the velocities, given in the initial data of the problem.
VA = velocity of passenger A, = 1.5[km/h], it is the same velocity of the sidewalk
VB = 2 + 1.5 = 3.5 [km/h], that is the velocity observed by a person outside from the sidewalk.
And from the perspective of passenger B the speed of passanger A is:
VA-VB = - 2 [m/s]
It means that the passenger B is seen how passenger A is getting close to him and then passed.
<u>Answer:</u>
Option (D)
Clockwise
<u>Explanation:</u>
Using Lenz's Law the current is induced in such a direction so that the magnetic field created due to the current induced opposes the increasing external magnetic field. For this case,when the field is increasing the magnetic flux increases and current is induced in clockwise direction (by lenz law as the induced field due to induced current has influence in opposite direction,thereby it reduces flux).
If the field is being decreasing,current would have been induced counter-clockwise so as to oppose the decreasing flux(as then the induced flux would be in same direction.)
