The Keck Telescope has a diameter of 10.0 m. When it is looking at
Mars, 7.38.1010 m from us, how far
apart are the closest objects it could
possibly resolve? Assume the light
has wavelength 633 nm.
[?] m
Remember: nano means 109

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?

If a substance is in the gas phase, which of qualities of the gas will stay constant? a: volume b: mass c: shape d: position of particles

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?
