sorry, beta is b i would like to solve the last equation. I would like to solve for 'b'. It is the only symbolic as the constants for the other letters are defined above

Homework Statement hey there, i'm trying to solve for beta which I tought i'd easily be able to figure out using MATLAB (i'm not the most proficient MATLAB user) but i can't get it to work.. Homework Equations The Attempt at a Solution My code is as follows: clear all...

Homework Statement Air inside a sealed tin can is initially at a pressure of 200 kPa and temperature of 20 ◦C. The tin can is known to burst at a pressure of 500 kPa. If the pressure is raised through heating, at what temperature will it burst? If you used an air compressor to pump up the...

am I expected to look up the internal energy on a superheated table and interpolate across to find the first internal energy?

how can i calculate the change of heat though, wiht what has been given to me?

Homework Statement I'm getting a bit stuck with this problem.. Given a volume, it's specific heat at constant volume, an initial temperature, pressure (atmospheric) and the power of a heater within this volume, I am expected to calculate the change in temperature for the body. Homework...

I'm a quite confused as to how to analysie a diode circuit How would I go about analysing the following? I know that I need to analyse the circuit with the diode on(short circuit) and off(open circuit).

looking only at the middle term, -50x of equation with unknown base, equating -5a=-65, we obtain a=13

okay shall give it a go!

Still not sure how I'm meant to solve for the base?!

Yess whoops c=5

Homework Statement 5x2-50x+125 (equation 1) Solutions are x=5 and x=8 (x-5)(x-8) = x2-13x+40 (equation 2) What is the base of the number system?? Homework Equations The Attempt at a Solution Compare coefficients 1a=5b -13a=-50b 40a=125b The base must be greater than 8...

Hi there, I'm having a great deal of trouble with this thermodynamics question. Cylinder filled with steam at 350 kN/m2. Initial volume is 0.05 m3. Sufficient heat transfer is effected to raise the internal energy in each cylinder by 50 kJ. The piston is moved slowly to maintain the...

I'm really confused at the moment and would quite appreciate some guidance. I've got little to no background in Matlab and am needing to plot a simple pendulum. I have found the equation of motion which is q(doubledot) = -(g/l)sin(beta) I don't know how to go about this? After...

Thx :)
