Amass of 5 kg stretches a spring 10 cm. the mass is acted on by an external force of 10 sin(t/2) n (newtons) and moves in a medium that imparts a viscous force of 2 n when the speed of the mass is 4 cm/s. if the mass is set in motion from its equilibrium position with an initial velocity of 3 cm/s, formulate the initial value problem describing the motion of the mass.

What is the role of the ocular lens?

Which statement correctly describes the relationship between frequency and wavelength?

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.
