One of the checks that you could do for problem 1) would be to check the output resistance of the Wheatstone bridge to make sure the bridge is not damaged. With no power connected to the bridge, you connect anOhmmeter to the outputpins. If each arm(branch)of the Wheatstone Bridge is 350Ω, what should the resistance read and why? (Draw the circuit and show your calculations.)

Space-time metric ds2= -dt2+at2dx2+bt2dy2+ct2dz2 (a)how does the area of a rectangle with vertices at ( x=0, y=0, z=0 ), (1,0,0 ), ( 0,1,0 ) and (1,1,0 ) changes with time? (b) if a photon moving in the x direction starts from the origin at t=1, when does it reach x=l? (ds=0 for the trajectory of a photon.) (c) the proper time for a particle is defined by cd=ds. what is the proper time for a particle to move along the trajectory ( x(t)=t, y(t)=0, z(t)=0 ) from t=0 to 1 ? what is the condition on the parameter a so that the velocity of the particle never exceeds the speed of light ?

The material that keeps its new shape after it is stretched is called?

An architect plans to use solar energy to heat the next house he designs. what principle of absorption and infrared energy can be applied to the design of the new house? how could she apply to those principals?
