A person’s basal metabolic rate (BMR) is the rate at which energy is expended while resting in a neutrally temperate environment. A typical BMR is 7.00 × 106 J/day. Convert this BMR to units of (a) watts and (b) kilocalories (or Calories) per hour. (c) Suppose a 1.00-kg object’s gravitation potential energy is increased at a rate equal to this typical BMR. Find the rate of change of the object’s height in m/s.

(a)

To determine

Convert BMR unit to Watts.

Explanation

Given Info: BMR 7.00×106J/day.

Convert BMR to Watt.

7.00×106J/day=7

(b)

To determine

Convert BMR unit to kilocalories per her.

(c)

To determine

The rate of change of objects height when a 1.00 kg object gravitational potential energy is increased at a rate equal to this typical BMR.
