Two Parallel plates have equal and opposite charges and are seperated by a di-electric 5mm thick of di-electric Constant 3. If the electric intensity in the di electric is 10^6v/m calculate; (A)The free charge per unit area on the conducting plates. (B)The bound change per unit area on the surfaces the di-electric (C)The Polarisation in the dielectric (E) The displacement in the di-Electric (E) The energy density in the dr-Electric ​

Acar tire contains 0.0380 m^3 3 of air at a pressure of 2.20 ×10^{5} 5 n/m^2 2 (about 32 psi). how much more internal energy does this gas have than the same volume has at normal atmospheric pressure, 1.01x10^5 5 pa?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

You are about to open a container of soy milk but notice that there are instructions to “shake well before serving.” the soy milk is most likely a
