Answer:
b
Explanation:
the ability for gases to compress is extremely helpful it allows tanks of oxygen to hold enough air for up to two hours and the strange thing about compression is that it allows some liquids to stay liquid at their boiling point allowing liquid nitrogen to stay liquid at room temperature
Current can flow only downhill in a water conduit because of "gravity". Gravity pushes everything here on earth downwards. If a water is situated in a tank the higher tank is lifted up the more water will flow. The water can only flow uphill if there is an energy that provides to move it upward.
You reach the max amplitude when all the energy is in the spring and the kinetic energy of the ball is zero.
Answer:
a)
b) imagen adjunta
Explanation:
a) Primero debemos hacer la conversión de 81 km/h a m/s, esto es 22.5 m/s.
Ahora, usando la ecuacion cinemática, en un movimiento acelerado tenemos:
Queremos encontrar la posición hasta detenerse, osea vf = 0.
b) Para este caso el gráfico se encuentra adjunto.
Espero que te sirva de ayuda!
