Science

The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.
A: actually any active components will oscillate with positive feedbackA transistor can be used as an amplifier along with an LC tank circuit to form an oscillator; it is an active device (as LIBURNO states) which will amplify the feedback signal coming out of the LC tank circuit. The tank circuit...

Median is finding the center of a line of some values. The values have to list in ascending order. When there are an odd amount of numbers: the median is the middle number. Example: find the Median of {12, 3, 5}. Put them in order: {3, 5, 12}. The middle number is 5, so the median is 5. When...

It turns to water and sometimes methane gas is released.
In desert plants the root hairs are more sensitive for water  absorption and can absorb water at times from the moist air present  in the porous soil. The root hairs of tropical rain forest plants  absorb only capillary water present in the soil.
sequellae     As long as the electricity is static, it is of little concern.  Of course, static today, current tomorrow.     I heard of a man who picked up two cables to connect them  and was cooked. The person in charge said it was static  electricity, since the power was then not...

You can calculate as follows:   * Convert the 4 inches to feet.   * Multiply the area by the thickness. The result, so far, will be  in cubic feet.   * Multiply this by the density of the base. If you have the density  in pounds per cubic foot, the answer will be in pounds.   * Convert...
Radium is a decay product of uranium and is constantly being  produced. U-238 has a half-life of about 4.5 billion years, so  there's still quite a bit left of the original amount on Earth.
980 square feet. Just multiply length by width - the answer is the square footage.
This means that playing is a crucial stage in the brain development  of any young animal.   It is a chance to act out the situations that they will have to  face in real life, but in a safe, controlled way.
Many problems accompany the project from the proposal to the  finish. The early disputes stressed on the economic and technical  factors. It was generally accepted that these two factors could not  support the construction of the project and the problem of  migration was hard to be settled....
ya it may be possible that by the using role scoper results in soil  erosion
The molecules of water are held together by hydrogen bonding between molecules.These are electrostatic bonds (attraction forces between opposite charges) that hydrogen makes with the oxygen of neighbouring molecules. Hydrogen, when bonded to oxygen to form water molecules, is slightly positive and...

Water is a 'Universal Solvent'. It can react easily with a more or  less anything because of it's two hydrogen atoms' free electrons.

They are different chemicals and one is a very strong acid and the  other is a very strong base, respectively.
The specific gravity for water is 1.  However, when the temperature of water increases, the gravity  gradually lowers. At 0°C (32°F), gravity is 1. At 100°C (212°F),  the specific gravity of water is 0.958. At 300°C (approx. 580°F),  it is 0.7.

It depends, an atom that has more charges of one kind than another  is called an ion. Obviously this is caused by the number of protons  and electrons compared to each other. If it has more positive  charges, it has more protons than electrons, making it a positive  ion. If it is a negative...

they increase in size as we get older, so we can never tell.
Namely through methods of conduction, and radiation. Conduction  means that although air particles are far, they are still close  enough to bump into one another and transfer some of that energy  kinda like a newton's cradle. Radiation means that electromagnetic  emissions of particles act like...
The common denominator of any two or more whole numbers will always be one (1) because common denominators refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1,...
