Net work done on student B by the Ferris wheel in moving from the top to the bottom is mathematically given as
net work done on A =0.
<h3>
Net work done </h3>
Generally the equation for the work energy theorem is mathematically given as
net work done on A = change in kinetic energy of A.
Where, angular velocity is constant.
change in kinetic energy = 0.
Hence, from work energy theorem,
net work done on A =0.

Answer:
Cost = 165.6 cents = $1.656
Explanation:
First, we will calculate the total energy consumed by the bulb in a month:
where,
E = Energy Consumed = ?
P = power = 23 W
t = time = (1 month)(30 days/1 month)(24 h/1 day) = 720 h
Therefore,
Now, the cost will be:
<u>Cost = 165.6 cents = $1.656</u>

No sorry, wish I could help
The cabinet is being pulled with 200N and is being rested by a force equal to 200N. That is why it is not being moved.
<span>Although the force of static friction can equal Fk=µs*F=m*g*µs=(30kg)*(9.8m/s^2)*(0.80)=235 N. It is not resisting the 200N force with 235N. Imagine if you pushed something with 200N and it pushed you back with 235N, especially a cabinet. You would think that the cabinet was alive.</span>
