Q: What is the centripetal acceleration of a point located 7.50 cm from the central axis of an ultracentrifuge spinning at a rate of 7.5 x 104 rev/min? A: The given rate of 7.5 x 104 revolutions per minute is converted to radians per second ( ⍵ ) in the latter stages of the solutionContinue reading “CENTRIPETAL ACCELERATION”

OSCILLATIONS AND WAVES: The Period of a Pendulum
Q: A pendulum has a length of 2.45 m. How many seconds will it take the pendulum to swing through one complete cycle? Does the mass of the pendulum influence the period? Why or why not? A: This question regards the period ( T ) of a pendulum. The period ( T ) is definedContinue reading “OSCILLATIONS AND WAVES: The Period of a Pendulum”
MATHEMATICS: Radius, Radians, Diameter, Circumference, and ” Pi ” = 3.14
C = 2πR. What does this mean? What is its usefulness? C = The distance around any circle. But where did such a formula come from? Start by drawing a circle. Within the middle of the circle, draw a dot. Now, draw a line that passes through the dot. This line should divide the circleContinue reading “MATHEMATICS: Radius, Radians, Diameter, Circumference, and ” Pi ” = 3.14″
MATHEMATICS: Is The Earth Really Round?
Disclaimer: The earth, according to current mathematical models and observations, is not flat. ROUND-EARTH MATHEMATICS : In determining the rotational speed of the earth, we must first assume that the sun is positioned an exceptionally far distance from the earth. If this were not the case, snow, water, and complex biological life would be non-existent.Continue reading “MATHEMATICS: Is The Earth Really Round?”
