Calculate the following, and write your answer to each in scientific notation. Try to do (a)–(i) first without the aid of your calculator, then check your answers by redoing them with your calculator.
Metric Conversions Worksheet I. These are the metric units. The letter in the first column is used as the prefix before the unit. Some common types of units are: grams (g), meters (m), liters (L), joules (J), seconds (s), and bytes (B).
Perform the following unit conversions: (When converting from one prefix to another, convert to the base unit first. Example from the this problem: TB B GB)
a) Use Newton's law of universal gravitation to calculate the gravitational force between the electron and proton in the hydrogen atom. b) Use 1.6 x 10-19 C as the elementary unit of charge to determine the force of attraction between the two particles.
Introduction. The determination of physical constants and the definition of the units with which they are measured is a specialised and, to many, hidden branch of science. A quantity with dimensions is one whose value must be expressed relative to one or more standard units.
28 Μαρ 2019 · ELECTRIC CHARGE, FORCE, AND FIELD EXERCISES Section 20.1 Electric Charge 13. INTERPRET We’ll estimate the charge your body would carry if the electron charge slightly differed from the proton charge. DEVELOP Since the human body is about 60% water, let’s assume that the number of protons/electrons per
