A fire hose ejects a stream of water at an angle of 31.1° above the horizontal. The water leaves the nozzle with a speed of 32.0 m/s. Assuming that the water behaves like a projectile, how far from a building should the fire hose be located to hit the highest possible fire?In meters
Speed isn't absolute. We are visiting at hundreds of km/s relative to a couple different objects in the universe. So if we get special answers for pace when measuring from one-of-a-kind features it's not ever possible to say how quick we are relocating. Thus the speed that we would journey at ( relative to the earth) is rather limitless. There are no in poor health effects of the pace itself. There can also be unwell effects of excessive acceleration. However that may be a thoroughly one-of-a-kind problem. Or ill effects triggered by a car that is not sufficient for the stipulations that it is subjected to. Eg a airplane in the surroundings have to stand up to the temperature and friction of the air. Once more this is not the velocity but effects neighborhood to being too close to the earth.

Your lab instructor will likely inform you whether contacts are allowed or not. If working with volatile chemicals, the chemicals can get from the air into the lenses so most people take their lenses off for their lab and put them in again after.
