Sobre un cuerpo de 1 kg masa, que se desliza sobre una superficie horizontal, actúan las fuerzas F1 y F2 como indica el esquema. Al pasar por el punto A, la velocidad del cuerpo es de 2 m/s. Sabiendo que la distancia AB vale 3 m. Calcular la velocidad que tiene al pasar por B. On a body of 1 kg mass, sliding on a horizontal surface, the forces F1 and F2 act as indicated in the diagram. As it passes through point A, the velocity of the body is 2 m/s. Knowing that the distance AB is worth 3 m. Calculate the speed it has when passing through B.

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

An electron is traveling with initial kinetic energy k in a uniform electric field. the electron comes to rest momentarily after traveling a distance d. (a) what is the magnitude of the electric field
