A52 kg woman cheats on her diet and eats a 540 kcal jelly donut for breakfast. (a) how many joules of energy are the equivalent of one jelly doughnut? (b) how many stairs must the woman climb to perform an amount of mechanical work equivalent to the food energy in one jelly doughnut?

a)801KJoules

b)The woman must climb stairs for an equivalent of 1.57km

Number of stairs=7850 stairs

Explanation:

a)We use the conversion between Joules and Kcal:

4184Joules=1Kcal

540Kcal*(1484Joules/1Kcal)=801KJoules

b)The physical Work must be equal to the food energy

The woman must climb stairs for an equivalent of 1.57Km

For example if an stair measure 20cm=0.2m

Number of stairs=1.57km/0.2m=7850 stairs

where's the following? you gotta add it to know what the choices are

explanation:

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
