En una prensa hidráulica, el área del émbolo menor es de 6 cm2 y la del émbolo mayor es de 48 cm2 . Cuando en el émbolo menor se aplica una fuerza “F”, en el mayor se obtiene una fuerza:

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?
