A shipwreck salvage company uses a lifting bag to raise a cannon off the sea bed. The bag is inflated with nitrogen to a volume of 5 m³ at the sea bed pressure of 300 kPa. Assuming no change in temperature, what would the volume of the lifting bag be at sea level where the pressure is 100 kPa?

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

unlike poles attract

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
