A thermometer with uniform scale placed in a mixture of ice-water at one atmospheric pressure gives a reading of 10℃. When using it to measure the temperature of boiling water, the degree is 90℃. If it measures the warm water in the container at 70℃, what is the actual temperature of the warm water?

What are the theoretical properties of a gas at a temperature of 0 kelvin?

Find the magnetic field a distance r from the center of a long wire that has radius a and carries a uniform current per unit area j in the positive z direction.

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
