Multiple questions: 1. 1 Tesla = ? Gauss 2. How many valence electrons are present in a pentavalent impurity? 3. What is the S.I. unit of the coefficient of linear expansion? 4. For an elastic collision, what is the value of the coefficient of restitution 'e'?
Understand the Problem
This is a series of multiple-choice science questions covering topics like electromagnetism, semiconductors, thermal expansion, and mechanics. The questions require recalling specific facts, definitions, and relationships between physical quantities.
Answer
1 Tesla = 10,000 Gauss; 5 valence electrons; 1/°C; 'e' = 1.
The answers are: 1 Tesla = 10,000 Gauss, pentavalent impurity has 5 valence electrons, S.I. unit of linear expansion is 1/°C, and for elastic collision 'e' is 1.

The answers are: 1 Tesla = 10,000 Gauss, pentavalent impurity has 5 valence electrons, S.I. unit of linear expansion is 1/°C, and for elastic collision 'e' is 1.
More Information
1 Tesla equals 10,000 Gauss reflects the conversion between units for magnetic flux density. Pentavalent impurities have 5 valence electrons, often used in semiconductors. The coefficient of linear expansion is measured as change per degree Celsius, and for elastic collisions, full energy restitution implies 'e' = 1.
Tips
Confusing the units for magnetic flux density or misunderstanding the properties of elastic collisions can often lead to mistakes.
