A person swims directly across a 30m wide river towards a target location. The person swims at 0.83m/s and the river flows at 3m/s. When the person reaches the other side, how far down the river are they from their initial target?

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

Two polarizers are oriented at 24.0∘ to one another. light polarized at a 12.0-degree angle to each polarizer passes through both. what is the transmitted intensity (%)?

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)
