2 Desde la terraza de un edificio se deja caer un globo lleno de agua, si no se tiene en cuenta
la fricción con el aire, ¿cómo se transforma la
energia del globo desde el momento en el que se
suelta hasta el momento en el que toca el suelo?
¿En qué cambiaria tu respuesta si se tiene en
cuenta la fricción con el aire?​

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

If a simple machine reduces the strength of a force, what must be increased?

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up
