Answer:
The 35-watt light bulb does a work of 46200 joules in 1320 seconds.
Explanation:
From Physics we remember the definition of work (), measured in joules, by the following integral equation:
(1)
Where is the power, measured in watts.
If the power is stable in time, then the work can be calculated by the following algebraic equation:
(2)
If we know that and
, then the work done by the 35-light bulb is:
The 35-watt light bulb does a work of 46200 joules in 1320 seconds.
About 46.1 pounds of apple would be needed per day of the trip.
I managed to extract the complete scenario from the attached image.
The trip is made up of 4 men and 3 women, making a total of 7 people.
Everyone has become accustomed to 1500 calories per day.
The total calories needed per day for 7 persons = 1500 x 7
= 10,500 calories
189 g of apple has only 95 calories, what g of apple will produce 10,500 calories?
= 10,500 x 189/95 = 20,889.67 g of apple
From conversion:
1 g = 0.00220462 pounds
20,889.67 g = 20,889.67 x 0.00220462
= 46.1 pounds of apple
