Identify the 4 fundamental units of measurement. What makes them 'fundamental'?
Meters, Kilograms, Seconds, Ampere. It is an intriguing fact that some physical quantities are more fundamental than others and that the most fundamental physical quantities can be defined only in terms of the procedure used to measure them. The units in which they are measured are thus called fundamental units.
How many nanometers are found in one meter?
1000000000
What is a 'conversion factor' when performing Dimensional Analysis?

A car is traveling at a speed of 33 m/s. (a) What is its speed in kilometers per hour? (b) Is it exceeding the 90 km/h speed limit?

1.3
the rule is that the last digit written down in a measurement is the first digit with some uncertainty. In order to determine the number of significant digits in a value, start with the first measured value at the left and count the number of digits through the last digit written on the right.

A model is something that displays something that is too difficult or impossible to display directly, and a theory is an explanation for something that happens in nature. 

2. Theories are less concise than laws and more vague, making them not "proven" like laws

3. Theories are not mathematically proven statements like laws are.

While a theory is an explanation of patterns that we have observed and verified by multiple people. 
What determines the validity of a theory?- Being verified by several groups of researchers and/or scientists who have also experienced the same events.
How does a theory differ from a law? - A theory is an explanation of patterns that has been supported by scientific evidence. A law is specified in the way it describes a pattern, also supported by scientific evidence and research. (For example, can be written like a math equation) ]]> 2020-09-22 14:39:30 UTC https://padlet.com/JKeeler/pbb7c3rebe/wish/768393492 1.1 Law williambennett6 https://padlet.com/JKeeler/pbb7c3rebe/wish/768494944 A mathematical equation is more like a law.
