A car of mass m1 and a trailer of mass m2 are parked on a slope that makes an angle of θ with respect to the horizontal. The car is held in place by a force of static friction from its tires. The wheels on the trailer are free to rotate, have no brakes, and have zero rolling friction. What is the tension in the towbar that connects the car to the trailer?

What is the stall speed at sea level of an airplane that weights 10000 lbs., has a wing area of 300ft^2, and a maximum lift coefficient of 1.4? what is the stall speed if flaps that double cl,max are applied?

Need asap ‼️ 20 pts which gravitational force field diagram is drawn correctly? (answers in pictures below)

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
