Ahorizontal beam of laser light of wavelength 585 nm passes through a narrow slit that has width 0.0620 mm. the intensity of the light is measured on a vertical screen that is 2.00 m from the slit. (a) what is the minimum uncertainty in the vertical component of the momentum of each photon in the beam after the photon has passed through the slit?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)

Lacie kicks a football from ground level at a velocity of 13.9 m/s and at an angle of 25.0° to the ground. how long will the ball be in the air before it lands? how far will the football travel before it lands?
