Fundamental physics concepts

A meter is the fundamental unit of length in the SI system, which is equal to 39.37 U.S. inches also, equal to one ten-millionth of the distance from the equator to the pole measured on a meridian through Paris its defined from 1889 to 1960 as the distance between two lines…

Is velocity the reason why a curveball drops? Statistics show that the velocity of a ball does not cause the curveball to drop. There are other variables involved like air pressure, rotation of the ball, and aerodynamics. These are very important factors when a baseball is thrown. A Big part of velocity is the air pressure, this is because of a separate topic called the Magnus Effect - a force exerted on a rapidly spinning cylinder or sphere moving through air in a direction at an angle to the…

1. Compare and contrast Radiological dispersal devices (RDD), Radiological exposure device (RED), and Radiological incendiary device (RID). Out of the three devices, Radiological Dispersal Devices are the most common. For one thing, these devices “…require limited technical knowledge…” that is why terrorists are more likely to make these bombs (Radiological Dispersion Device, n.d.). Also, because of that, there is not one standard specific model for Radiological Dispersal Devices; each device…

constant temperature, the pressure of a gas increases as the volume of its container decreases. Pressure is defined in physics as force divided by area (P = force/area). According to the kinetic-molecular theory,…

ANEROID – sensitive component in an altimeter or barometer that measures absolute pressure of the air. -Sealed, flat capsule made of thin corrugated disks of metal soldered together and evacuated by pumping all of the air out of it. PRESSURE – amount of force acting on a given unit of area and all pressure must be measured from some known references. BAROMETRICSCALE/KOLLSMAN WINDOW- small window in the dial of a sensitive altimeter in which the pilot sets the barometric pressure level from…

This chapter contain the physical model and numerical procedure of calculating the dynamics of space charge and electric field distribution in cable insulation material under DC voltage. Electric field distribution and formation of space charge The dependency of electric field distribution on time and temperature is obvious in HVDC system. This is due to the resistivity/conductivity dependency on temperature and electric field [1, 44]. It is also clear that the formation of space charge within…

Scientific Objectives The scientific objectives of the experiment were to measure the temperature of a sample of lauric acid as it 's cooled. The data was manipulated to generate a cooling curve and freezing point. Introduction Matter can be categorized as solid, liquid, or gas this is known as phases of matter. A solid is a sample of matter with a defined volume and a defined shape; this sample is not easily compressible and doesn’t flow smoothly. A liquid has an undefined shape and a fixed…

INTRODUCTION There has been significant recent work on Vlasov-Maxwell (VM) equilibria that are consistent with nonlinear force-free1–8 and “nearly force-free”9 magnetic fields in Cartesian geometry. Therein, force-free refers to…

Weeks 7 to 9 Assignment Question 1- The difference between heat and temperature is that heat is measured by temperature. Heat travels from areas of higher temperatures to areas of lower temperatures. Temperature indicates level of heat present. (Hammer & Price, 2001, p. 292). Question 2- The principal means by which heat can be transferred are radiation, conduction, and convection. Radiation is the only way the sun's heat reaches earth. Body with temperature above absolute zero will emit…

Where P is the permeability coefficient, Q is the amount of permeant passing through the material, x is the thickness of the plastic film, A is the surface area available for mass transfer, t is the time, and ∆p is the change in permeant partial pressure across the film. Hence the permeability coefficient (P) is the proportionality constant between the flow of the penetrant gas per unit film area per unit time and the driving force (partial pressure difference) per unit film thickness. The…
