Answer:

The resolving power remains same.

Explanation:

The resolving power of the lens is directly proportional to the diameter of the lens not on the focal length.

As the diameter is same but the focal length is doubled so the resolving power remains same.

energy expenditure due to physical activity generally accounts for __________ of total energy expenditure.
olga_2 [115]

Answer:

Energy expenditure due to physical activity generally accounts for 20% of total energy expenditure.

Explanation:

The total amount of energy your body uses daily is usually divided as follows:

1. Your Basal Metabolic Rate at rest  (50-70%)

Basal Metabolic Rate is the number of calories required to keep your body      functioning at rest

2. Consumption by your daily physical activities (20%)

3. Energy to digest food. (10-20%)

This energy has to be deducted from the overall energy content of the food itself.

Then, the answer is:

Energy expenditure due to physical activity generally accounts for 20% of total energy expenditure.
