Plasma is a form of matter in which many of the electrons wander around freely among the nuclei of the atoms. Plasma has been called the fourth state of matter, the other three being solid, liquid and gas.
Normally, the electrons in a solid, liquid, or gaseous sample of matter stay with the same atomic nucleus. Some electrons can move from atom to atom if an electrical current flows in a solid or liquid, but the motion occurs as short jumps by individual electrons between adjacent nuclei. In a plasma, a significant number of electrons have such high energy levels that no nucleus can hold them.
An atom that has lost some of its electrons, thereby attaining an electric charge, is an ion. When a gas is subjected to heat or an electric field, some of its atoms become ions, and the gas is said to be ionized. An ionized gas, unlike a gas in its normal condition, can conduct electrical current to a limited extent. If the heat or electric field becomes extreme, many of the atoms become ions. The resulting super-ionized gas is a plasma, which can conduct a large and sustained electric current.
The behavior and properties of plasmas have aroused interest and creative work among scientists and engineers. Applications include electric lamps, lasers, medical devices, energy converters, water purifiers and flat-panel video displays. About 99% of the visible universe is formed of plasma.
Answer:
Not enough information. For this to be SAS, the single tick mark would need to be located on the line CB and ED.
Step-by-step explanation:
Let p be 0.831 denote the percentage of defective welds and q be 0.169 denote the percentage of non-defective welds.
Using the binomial distribution, we want all three to be defective.
Answer: The length is 15 inches and breadth is 9 inches
Step-by-step explanation:
Given : Area of rectangular sheet = 135 square inches
Perimeter of rectangular sheet = 48 square inches
Now Area of rectangular sheet = 
= 135 square inches
perimeter of rectangular sheet = 
= 48 square inches
Thus 
= 24 square inches
Thus Length = 15 inches
Breadth = 9 inches
Decide whether the statement is true or false. If false, provide a counterexample.
1. The equation 2x - 7 = 5 + x has exactly one solution TRUE
2. If x^2 = 16, then x must equal 8 or -8 TRUE
3. February 14 is Valentine's Day TRUE
4. If you visisted the Statue of Liberty, then you've been to New York TRUE
5. A point may lie on at most two lines FALSE A point may lie on more than zero to an infinite number of lines.
Write the converse and contropositive of each statement.
6. If you like tennis, then you play on the tennis team FALSE You don't have to. Haha.
7. If x is odd, then 2x is even TRUE
8. If m
