First and foremost, I admit that this was not my strong point in physics. I am trying to construct a realistic model in excel or maple which could be used to predict induced voltage in a solenoid based on it's distance to a virtually infinite extremely high voltage, power source.
The source...
I have been working on what I thought was an easy problem. This was a one hour quiz in which the whole class failed, the instructor decided to give it as a homework assignment instead.

Considerable interest exists in the conversion of coal into liquid products...
No, believe me, I do appreciate your help. but I would rather go elsewhere than deal with rude comments. If you feel that I should set your comments aside then maybe you shouldn't be making them in the first place
Alright, I admitted I didn't know what I was doing, you don't have to be a jerk about it.
anyway,
I tried it again, and I think I see where I screwed up, I skipped too many steps. This time I got an answer of 64.7C which makes a bit more sense.
question... well two actually.
I used 200g...
It seems like that should be mathematically equivalent. I suppose I just don't completely follow.
If all of my Q values from the system are in equilibrium at 100C, I would think I could set it equal to the heat of the final cube to get the final temperature. If this is correct, I can't see why...
I've never had to do one quite like this. Just wanted to check my work.
Homework Statement
150g of water and 50g of ice are in a container made from 20.0g of aluminum. The system consisting of the water, ice and the container are at thermal equilibrium at 0C. The container is wrapped in a...
Homework Statement
a block of ice slides down a frictionless ramp at angle Θ = 52.0° while an ice worker pulls on the block (via a rope) with a force that has a magnitude of 52.0 N and is directed up the ramp. As the block slides through distance d = 0.8 m along the ramp, its kinetic energy...
Homework Statement
A helicopter lifts a 72 kg astronaut 10 m vertically from the ocean by means of a cable. The acceleration of the astronaut is g/16. How much work is done on the astronaut by (a) the force from the helicopter and (b) the gravitational force on her? Just before she reaches...
Homework Statement
A train at a constant 42.0 km/h moves east for 33 min, then in a direction 64.0° east of due north for 25.0 min, and then west for 69.0 min. What are the (a) magnitude (in km/h) and (b) angle (relative to north, with east of north positive and west of north negative) of...
