Why does water fill the bottom of a glass rather than cling to the side
Answers
When you pour water into a glass, gravity is pulling the water down to the bottom of the glass instead of pulling it to the sides and since glass is a substance that glass easily rolls off of, it is easier for the water molecules to locate at the bottom.
In what way does varying the length of a string of a violin change the vibration and how does this affect the sound that's produced?
Answers
The wavelength is the so-called "fundamental" wavelength, or the "first mode." Thus, the wavelength of the string's vibration is defined by the supports, and has nothing whatsoever to do with mass or elasticity.

The method of heat transfer by which the sun warms the earth is
Answers
Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection.
Conduction and convection both require some kind of material stuff between the heat source and the object being heated.
Since there's no material stuff in the space between the sun and the Earth, conduction and convection can't do it, and the only way for the sun's energy to reach the Earth is by radiation.
