Daniel, The question is as followed: In a simple circuit 6-volt dry cell pushes charge through a single lamp whiich has a resistance of 3 ohms. the current through the circiut is 2 amps. If a second identical lamp is connected in series, the 6 volt battery must push a charge through a total...

If a single lamp has resistance of 3 ohms, and a second and third identical lamp is added wouldn't the second be 6, and third be 9. If a part of an electric circuit diaaipates energy at 6 when it draws a current of 3A, what voltage is impressed across it? What does 6 represent

O.K. HOw much heat is absorbed by a person's hand if steam at 100degree C is first converted to liquid water at 100 degree C and then cooled to normal body temperture? I'm not sure of the formula for this one.

Thanks for the help. I have completed the activity. I appreciate you. :smile:

O.K Mathechyst I got completed lost. I didn't see were you converted k/m into m/s. I'm sorry but i guess I'm missing the whole concept

No I do not know what mass is in terms of velocity and energy

If I'm looking for mass am I suppose to know?

O.K . What is 1*10(6power)J mean. Do I further need to break this down in order to work the problem. Problem: A car travleling 25 km/hour has Kinetic energy of 1*10(6power)J. What is the mass of the car? I've converted k/h to m/s

I have searched for this answer all day long. Why is Vave multiplied by 2 to obtain Vf?

If I take these steps will I be able to find the mass of the car?

the equation is KE=1/2mv(squared)

An automobile traveling 25km/hour has kinetic energy equal to 1*10(6 power)J all i know is KE=mass*km/hour What is the mass of the car?
