SEQUENTIAL ENERGY LOSSES IN A CHAIN REACTION: A Practical Application of Exponential and Logarithmic Mathematics
A row of evenly spaced dominoes, each with a mass = 100 g ( 0.1 kg ) and height h = 0.2 m, is placed on a flat horizontal surface. The 1rst domino that falls delivers 5J of energy to the 2nd domino in line. Energy losses due to friction and air resistance occur betweenContinue reading “SEQUENTIAL ENERGY LOSSES IN A CHAIN REACTION: A Practical Application of Exponential and Logarithmic Mathematics”

My latest numerological pursuits, and introduction to my newest pet project: a dropshipping e-commerce storefront called ” The 7th Dimension Cloud-Merchandise Depot “.
SPECIAL TOPICS: 6,000 Watt ( W ) Craftsman Generator Instructions
6,000 Watt Craftsman Generator Instructions: This covers most of the important steps, but other procedures regarding troubleshooting and periodic maintenance can be found within the Craftsman operator’s manual ( https://www.craftsman.com ) From this point onward, we all need to try to get cheap tents that are small enough for 1 person per person in ourContinue reading “SPECIAL TOPICS: 6,000 Watt ( W ) Craftsman Generator Instructions”
SPECIAL TOPICS: Nature Seems to Love the Number 3
Along with disastrous 3-point shooting in NBA basketball…lol. Three points are awarded for field goals in football, and no NBA team has ever been down 3 games in the playoffs yet win a 7-game series. DNA can exist in 3 hybridized states within a cell. There are 3 bases on a baseball field away fromContinue reading “SPECIAL TOPICS: Nature Seems to Love the Number 3”
MAGNETISM AND ELECTROMAGNETISM: Lenz’ Law
Q: A loop that consists of 200 ( N ) turns and an area ( A ) of 0.25 m2 is located in a downward-directed magnetic field ( B ) of 0.40 T. Additionally, the loop’s coils have a resistance ( R ) of 5.0 Ω. If the coils are crushed to an area ofContinue reading “MAGNETISM AND ELECTROMAGNETISM: Lenz’ Law”
MAGNETISM AND ELECTROMAGNETISM: Electromagnetic Induction and the Electromotive Force ( emf )
Q: A metallic coil that consists of 200 ( N ) turns encloses an area ( A ) of 100 cm2. The coil is placed within a magnetic field ( B ) that is perpendicular to its area, and it has a magnetic flux density of 0.50 T. Next, the field is shut off, andContinue reading “MAGNETISM AND ELECTROMAGNETISM: Electromagnetic Induction and the Electromotive Force ( emf )”
INTRODUCTION TO ELECTRONICS: Conventional Current, Kirchhoff’s Laws, Magnetic Fields, and the Right-Hand Rule
Conventional current refers to the convention in which electrical current ( I ) is considered to be a flow of positive charges. The usefulness of this convention is readily observable when dealing with Kirchoff’s Laws ( or Rules ) and the analysis of magnetic fields that encircle a conductor that carries a conventional current. OfContinue reading “INTRODUCTION TO ELECTRONICS: Conventional Current, Kirchhoff’s Laws, Magnetic Fields, and the Right-Hand Rule”
MATHEMATICS: The Unit Circle, Sine, Cosine, and Tangent Functions
Linear momentum ( p ) will be maximally conserved when two particles moving towards one another with a constant velocity ( v ) along a straight line collide: p1i + p2i = p’1f + p’2f Things become somewhat more complicated when some measurable entity is maximized or minimized when it passes through some other entityContinue reading “MATHEMATICS: The Unit Circle, Sine, Cosine, and Tangent Functions”
INTRODUCTION TO ELECTRONICS: DC Motors
We have seen how a conducting wire moving with respect to an electric field ( B ) will experience forces upon its electrons. Consider the diagram below: Due to the proper ( perpendicular ) alignment of the loop and magnetic field, the maximum amount of DC current will be produced; however the voltages and currentsContinue reading “INTRODUCTION TO ELECTRONICS: DC Motors”
