Answer:
All the meteors in a meteor shower typically come from the same comet, which is in a periodic orbit around the Sun. The dust from the comet follows the path of the parent body and as Earth intersects the debris along the comet's orbit, it plows into this material. Since the dust particles are all moving together in space before they encounter Earth, if you trace back the streak of each meteor, its path will appear to diverge from one place in the sky.
Answer:
Pressure = Density x Gravity acceleration x Height
Density of water = 1000 Kgm^-3
Gravity acceleration = 9.8 ms^-2
So it is 4.50.

The molecules of a solid vibrate faster so that they start spreading out to become a liquid. This energy makes them vibrate faster so the bonds between molecules can't interact all that well anymore creating more distance. The stronger the bonds between the molecules the higher the energy (temperature) has to be to get them away from each other. Hope I didn't confuse you too much!
In a scientific experiment, control, independent variable and independent variable have to be present in order to allow for proper manipulation of the experimental parameters. Control are used in experiments to compare other variables. The independent variable is used to modify the dependent variable. The dependent variable is the variable that is been tested, it is used to verify the stated hypothesis of the experiment.
