Un automóvil viaja a una velocidad constante de 120 km/h, al frenar tarda 10 s en detenerse. a) ¿Cuál es la distancia que recorre desde que inicia el frenado hasta detenerse?. b) ¿Con que velocidad chocaría a otro vehículo y, ubicado a 30m del lugar donde aplicó los frenos?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
