Monochromatic electromagnetic radiation with wavelength lambda from a distant source passes through a slit. the diffraction pattern is observed on a screen 2.50 m from the slit. a: if the width of the central maximum is 6.00 mm, what is the slit width if the wavelength is 500 nm (visible light)? b: if the width of the central maximum is 6.00 mm , what is the slit width if the wavelength is 50.0 um (infrared radiation)? c: if the width of the central maximum is 6.00 mm, what is the slit width if the wavelength is 0.500 nm (x rays)?

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 .

When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(ii) sulfate is reduced to lead at the cathode and oxidized to solid lead(ii) oxide at the anode. suppose a current of is fed into a car battery for seconds. calculate the mass of lead deposited on the cathode of the battery.
