with respect to changes in V and T, that

dS=k.N.dV/V+C/TdT

A metal bar is free to slide along these rails. If the bar moves along the rails with constant velocity v in the presence of a vertical magnetic field B, show using faraday's law in integral form that the magnitude of the voltage V induced between the rails is given by

V=Bvd

1)

1 cm^3 of ideal gas at standard temperature and pressure expands freely into an equal volume so that the volume at the end of the expansion is twice the starting volume

2)

Two unlike ideal gasses occupying different, but identical, volumes (1 cm^3) at standard temperature and pressure which are initially separated by a partition are allowed to diffuse into each other. THe total volume occupied by each gas after the diffusion. The total volume occupied by each gas after the diffusion is therefore twice the starting volume.

3)

Two equal volumes of the same gas (1cm^3) at standard temperature and pressure are separated from each other by a partition which is removed to create twice the volume at standard temperature and pressure.

power output is 15W and the cross sectional area is 1mm

I have no idea where to even start

why cant you get two like quarks in a pair e.g two up quarks?

I've got to program a ball to move in a circle radius 5 units and dont know how

What velocity would a spacecraft need to be travelling for it radio tunes to 92.4Mhz to pick up 94.6Mhz?

The Steering on my W reg clio is quite heavy, it may be that my car doesnt have power steering but if it does is there a way i can adjust the power steering and make it a bit lighter?

I've got to model motion on a plane using a visual modelling program the object is accelerating down a slope under gravity (9.81ms^-2) the angle of the slope is 30 degrees i need to write the value for the acceleration in vector form for the vertical and horizontal components

I think this might have got worse recently because i only just noticed, if i hold my finger in front of my face and focus on it everything in the background is totally blurred, and if i focus on something in the background my finger's just a blur. is this my eyes or are human eyes just rubbish?

I'm in the middle of an experiment using a diffraction grating and need to work out the error in slit width, the grating has 5.905*10^5 slits per meter and the error is plus, minus 500 per metre. the slit width is 1.6 micrometers.

I'm writing a program to tell in a number input is a leap year or not, the statement has to be if x is divisible by 100 and divisible by 400 then its not a leap year the statement i've got is

IF x/100=INTEGER AND x/400=INTEGER THEN

if it satisfies these requirements then it will print 'this is not a leap year'

I'm new to if statements so i don't know if i can use AND and I'm not sure if =INTEGER will work either

I had an accident a couple of months ago, my car was written off so i bought another car which i've now sold because i dont really need a car, but my insurance company wants me to pay the remains of my policy, i take it there's no way to get out of this?

y=-(a/x)^7+(b/x)^13

a and b =10^-10

need dy/dx

In march i've got to get the train from hull to London, is there a train service that offers wi-fi so i don't die of boredom?

A Wheatstone circuit comprising of 5 resistors each 10 ohms, since there is no current within the circuit (because there is no supply attached) wouldn't the Resistance in one resistor be 10 ohms?
