A 4.47 kg particle has the xy coordinates (- 1.13 m, 0.557 m), and a 2.85 kg particle has the xy coordinates ( 0.923 m, - 0.661 m). Both lie on a horizontal plane. At what (a) x and (b) y coordinates must you place a 2.98 kg particle such that the center of mass of the three-particle system has the coordinates (- 0.199 m, - 0.741 m)

An object is 10. cm from the mirror, its height is 3.0 cm, and the focal length is 2.0 cm. what is the image height? (indicate the object orientation by including the + or - sign with the answer.) hi = cm +1.33 -1.33 +0.75 -0.75

Select all of the following that are equal to an impulse of 20 unitsa) force= 5, time= 5.5b) force= 25, time= 0.8c) force= 0.1, time= 200d) force= 10, time= 2(its b, c, and d)(also in order to find answer they have to add to get the unit)ex= 25x.8=20 or .1x200=20

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
