You are the engineering duty officer getting your submarine, the uss greenville, ready to put to sea. when nuclear material in the reactor is fissioning at an increasing rate, this is known as a:
porque la cantidad de gases de efecto invernadero alcanzó un nuevo máximo sin precedentes, causando daños muy graves a esta, por eso es importante monitorearla, para controlar el porcentaje de daños que esta causa y poder reducirlo o mantenerlo.
the frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. this makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.
average speed = (total distance covered) / (time to cover the distance)
total distance = (80m) + (125m) + (45m) = 250 meters
overall time = 10 minutes
average speed = (250 meters) / (10 minutes)
average speed = 25 meters/minute
since we're only looking for average speed and not velocity, we don't care about any of the directions, and we don't need to calculate mary's displacement.
correct answers are 1.an increase or decrease in pressure 2.an increase or decrease in energy
all existing matter can undergo phase change it means they may transform from one state to another. phase change of a matter may occur due to change in energy and change in pressures.
for example there is an ice cube which is a solid and if we want to change it phase into liquid water for that purpose we have to supply some energy to ice cube it means we have to give some heat to ice cube. after supplying heat energy to the ice it will turn into water it means there is phase change from solid to liquid due to supplying the heat. similarly we can change the liquid water into solid ice cube by taking heat energy(reducing temperature) from the liquid water .
in some cases the matter doesn't want to undergo phase transformation. for example, oxygen will solidify at -361.8 degrees fahrenheit at standard pressure.but , it can change to solid state at warmer temperatures when the pressure is increased.
