The label on a candy bar says 410 Calories. For the steps and strategies involved in solving a similar problem, you may view a Video Tutor Solution. Part A Assuming a typical efficiency for energy use by the body, if a 60 kg person were to use the energy in this candy bar to climb stairs, how high could she go?

2.9174meters.

Explanation:

410Calories = 1715.44 Joules (Energy).

we have essentially calculate height at which Gravitational potential is 1715.44 Joules.

We know that Gravitational Potential as a function of height above reference point is.

.

Substituting values in gives.

in above solve for h and you will get.

h = 2.917meters (units are meters by dimentional analysis ).

That is the height a 60Kg person can reach by climbing stairs.

technology is the application of the knowledge gained by science.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
