Answer:
T = 4200N
Explanation:
When the submersible craft is at rest, the tension in the cable is 6000N.
With this information you can calculate the weight of the craft by summing the forces (the summation of the force is zero because the craft is at rest):
When the craft is going down with a constant speed, there is a drag force of 1800N. Then, by using the second Newton law you have:
(1)
Fd: drag force
The summation of the forces is zero because the craft moves with constant velocity, that is, there is no acceleration.
You calculate the new tension on the cable by solving the equation (1) for T:
hence, the tension is 4200N
i am sorry. but no matter how much I calculate, I get 6 microF as the answer.
are you sure it's 7 microF .
(please check if you have added them according to serial and parallel methods)
and also there is a connecting wire (marked in orange)
