A student needs to move a large carton of books with a total mass of 120 kg, to get a better view out the window. The coefficient of static friction (μs) between the cardboard boxes and the tile floor is 0.42, and the coefficient of kinetic friction (μk) is 0.30. With what horizontal force will the student have to push in order to get the stack of books to start moving? Round to the nearest whole number and include units.

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

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 = 2.6 m below the tank bottom which is a = 6.7 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). report your answer in meters to two decimal places.
