Will mark brainliest and | asap which of these is a similarity between a polar and a subtropical jet stream? both bring in cool air from the poles. both are formed at latitudes close to the poles. both are formed at latitudes close to the equator. both are formed at the boundary of warm and cool air masses.

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

Two polarizers are oriented at 40∘ to each other and plane-polarized light is incident on them. if only 16 percent of the light gets through both of them, what was the initial polarization direction of the incident light?

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)
