    Reactor fuel and waste: fission/fusion problem

    Homework Statement In this problem, we're going get a rough estimate the amount of uranium fuel it would take if the US received all its electrical power from nuclear power plants. The size of a power plant in normally given as the about of electrical power it can produce when running a...

    Intro Thermodynamics equilibrium problem

    Thanks for the help! I figured it out. The ice cube goes from 263 K to 273.15 K, then a phase change from solid to liquid, then the liquid(water) increases in temperature to the final temperature,which is the temperature of equilibrium for the system.

    Intro Thermodynamics equilibrium problem

    Homework Statement A 3.6-kg block of ice originally at 263 K is placed in thermal contact with a 13-kg block of silver (cAg = 233 J/kg-K) which is initially at 1006 K. The H2O and silver system is insulated from any other heat transfer. 1)At what temperature will the system achieve...

    Angular momentum sliding beam

    Homework Statement A uniform beam with mass M = 156 kg and length L = 2.3 m slides broadside down along the ice at a speed of v0 = 9 m/s. A man of mass 88 kg, who is initially at rest grabs one end of the beam as it goes past and hangs on as the beam and man go spinning down the ice. Note...

    Comp Sci Sorting array into ascending order in C++

    Here is a slightly better attempt at the first part of the problem. I am now stuck on how to transfer the positive and negative arrays to the display function and show the arrays on the screen by way of the display function. Also I just realized the...

    Comp Sci Sorting array into ascending order in C++

    Homework Statement a. Define an array with a maximum of 20 integers values, and fill the array with numbers input from the keyboard or assigned by the program. Then write a function named split() that reads the array and places all zeros or positive...

    Kinematics, Newton's Laws, Fun With Engineers

    In class we have only covered 1d, 2d kinematics, and Newton's laws. I know momentum is just a restatement of Newtons's 2nd law, but it has not been covered in class yet. The professor insists that this problem can be solved correctly using what was...

    Kinematics, Newton's Laws, Fun With Engineers

    Well I tried what you said doing constant velocity but the automated homework system says the answer is still wrong.

    Kinematics, Newton's Laws, Fun With Engineers

    Homework Statement As a prank, your friends have kidnapped you in your sleep, and transported you out onto the ice covering a local pond. Since you're an engineer, the first thing you do when you wake up is drill a small hole in the ice and estimate the ice to be 6.7cm thick and the distance...

    1-d kinematics food fight in space

    No the banana does not have any acceleration. I ended up multiplying the velocity of the banana by the elapsed time, which gave me the distance it traveled. Then adding that answer to 6m gave me the correct answer. Thanks for your help!

    1-d kinematics food fight in space

    Homework Statement Having aced your Physics 2111 class, you get a sweet summer-job working in the International Space Station. Your room-mate, Cosmonaut Valdimir tosses a banana at you at a speed of 14.0 m/s. At exactly the same instant, you fling a scoop of ice cream at Valdimir along...
