Answer from: esta54

Lily, Astrid, Henry, and Bob are all recording their answers in Joules. One reason this is known is that they are all experimenting and recording different types of energy. The answer is, Therefore, C. Plus i got this question right that is another reason i know. Who would not record in joules when recording energy, its the universal unit for work or energy. I hope this helps you whoever is out there who is lazy and does not want to do it themselves... Oh wait that is how i found this website. nvm, we are the same Xd

Answer from: dmoulthrop3929

The correct answer to the question is C.) Lily,Astrid, Henry, and Bob.

EXPLANATION:

As per the question, we have two physical quantities . One is work and the other one is energy.

Energy and work are inter convertible in nature . The energy of a substance is defined as its ability to do work . Hence, work will be done on the body or by the body in the expense of energy.

From above, we see that both energy and work have to be measured in same units.

The unit of work is joule [ J ] . Hence, the unit of energy must be joule.

As per the question, Lily and Astrid are measuring the change in energy in different systems which is to be measured in joule unit.

Again Henry and Bob are measuring work done by different systems. The work done is also measured in joule unit.

Hence, all the persons will record their measurements in joules.

Answer from: Quest

The charge of an ion with 55 protons and 52 electrons is +3. the reason is because protons are positive, and there are three more than the amount of negative electrons.

Answer from: Quest

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)
