By measuring the potential energy of an object relative to the ground, and the object's mass, you can calculate its speed when it hits the ground. Explain why you can do this. A. because gravitational potential energy can convert to elastic potential energy
B. because gravitational potential energy can convert to kinetic energy
C. because the gravitational potential energy can convert to sound energy
D. because gravitational potential energy can convert to electric potential energy

Porque crees que el agua no podia subir mas de 10 m de altura con ese tipo de bomba

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:

The air that we breath is made mostly of which gaseous molecule
