A parallel plate capacitor with circular plates has a steady charging current of 5.0 Amps. The wires into and out of the plates attach to the plate centers. If the radius of each plate is 40 mm and there is no dielectric between the plates, what is the magnetic field magnitude at a position that lies between the plates and is 30 mm from the (imaginary) line joining their centers

What happens to the light rays when they hit the specimen?

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .

The molecular mass of a gas is (select all that apply) a. independent of the type of gas b. the same number as the atomic (or molecular) mass, but measured in grams c. dependent on the temperature d. the mass of a mole of the gas
