A bubble of air has a volume of 2.0 cm at the bottom of a lake where the total pressure is 3.0 x 10 Pa . The temperature of the water in the lake is constant. The atmospheric
pressure at the surface is 1.0 x 105 Pa
What is the volume of the bubble when it rises to the surface ?

Each student aligns the edge of the object with the left edge of the ruler as shown above. all four students read the ruler with a measurement of 4.6 cm. which statement describes the data they collect? i believe the answer is: the data have poor precision and poor accuracy because of a systematic error.

Because there is no air in the jar, the vibrations can not travel through the air and create sound.  (that's why there is no sound in space, there is no air)

Following the american gauge wire standards ,the larger gauge number, the slimmer the wire and thus the smaller current carrying capacity it can have.then both statements would be incorrect, as they are saying the opposite of what it is actually is.(smaller gauge numbers have thicker wires and can carry more current)
