For the rotational part of the experiment, a student measures a force of 1.8 n when the radius is 12 cm and the angular velocity 10 rad/s. a. what is the total mass of the object undergoing uniform circular motion? b. if the same mass (at the same radius) is rotated at 5 rad/s, what will be the measured force?

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)

What causes the formation of ocean currents?

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
