Answer:
Work done, W = 141174 Joules
Explanation:
It is given that,
Constant tension acting on the boat, T = F = 465 N
Speed of the boat, v = 4.6 m/s
Time, t = 1.1 min = 66 seconds
Let W is the work done by the tension. It is equal to the product of force and displacement. It is given by :

Since, 


W = 141174 Joules
So, the work is done by the tension is 141174 Joules. Hence, this is the required solution.

Answer:
Explanation:
Incandescent bulbs are extremely inefficient because 90% of the energy is wasted as heat, with only 10% being converted to visible light. This gives incandescent bulbs a luminous efficiency rating of around 2%. Ultimately, incandescent bulbs perform better as heaters than as light sources.
