Science Quiz: Bonds and Nat. Phenomena

Study Notes

Chemical Bonding

Non-metal atoms typically share electrons to form covalent bonds.

Electric Current

The unit of measure for electric current is the Ampere (A).

Photosynthesis

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy, typically glucose, which is then used for growth.

Earth's Structure

The layer of Earth primarily composed of molten rock is the mantle.

Ring System

Saturn is the celestial body primarily recognized for having a prominent ring system, largely composed of ice and rock particles.

Cost-Benefit Analysis

A structured method for evaluating project/decision strengths and weaknesses.
Costs represent all expenses associated with a project.
- Fixed costs remain constant regardless of output.
- Variable costs fluctuate with output levels.
Benefits are gains from the project, typically measured in monetary terms.
Steps:
- Identify and classify costs and benefits.
- Assign monetary values to costs and benefits.
- Compare total costs to total benefits.
- Calculate Net Present Value (NPV) to account for the time value of money.
- Make a decision based on whether benefits outweigh costs.

Demand Analysis

Examines consumer purchasing behavior and its influencing factors.
Law of Demand: As the price of a good decreases, the quantity demanded increases, and vice versa.
Demand Curve: A visual representation of the relationship between price and quantity demanded.
Factors Affecting Demand:
- Price of the good
- Consumer income (normal goods and inferior goods)
- Related goods' prices (substitutes and complements)
- Consumer preferences and tastes
- Expectations of future price changes
Elasticity of Demand:
- Price Elasticity: Measures the responsiveness of quantity demanded to changes in price.
- Elastic (E > 1): Demand is sensitive to price fluctuations.
- Inelastic (E < 1): Demand is relatively unresponsive to price changes.
