A glass of iced tea contains a large chunk of pure ice partially floating on the iced tea. Given the density of ice as 917 kg/m^3, and density of iced tea as 1008 kg/m^2. 8. Find the percent volume of ice that is floating above the water level. 9. Convert 2.5 atm into Pascal, lb/in^2, and kPa.

A baggage handler at an airport applies a constant horizontal force with magnitude F₁ to push a box, of mass M, across a rough horizontal surface with a very small constant acceleration a. ( Figure 1) Figure 2F Submit ▾ Part B Now assume that the baggage handler pushes a third box (Figure 2) of mass m/2 so that it accelerates at a rate of 2a. How does the magnitude of the force F that the handler applies to this box compare to the magnitude of the force F₁ applied to the first box? ▸ View Available Hint(s) 0 2F Submit

Two objects are placed near one another the mass of one object is doubled while the other distance between the objects is tripled what net change takes place in the force of gravity between the objects

(2) The box with M = 40kg shown below is being pulled by two pulleys exerting forces F₁ = 400 N (0₁ = 60°) and F₂ = 200 N (0₂= 15°) up an incline with an angle 0₁ = 30°. If the uk = 0.15. What is the acceleration of the box? Would the F₁ or F₂ be enough alone to pull the box up if the other pulley would stop working?
