What is the direction of the magnetic lines of force? Lines of force always form individual CLOSED LOOPS around the magnet. Lines of force have a definite DIRECTION from North to South. Lines of force that are close together indicate a STRONG magnetic field. Is a magnet made with iron nickel or cobalt? There is […]
What does the coefficient of static friction depend on?
What does the coefficient of static friction depend on? Already Coulomb presented experimental evidence that the static coefficient of friction may depend on time, on normal force, on the contact size, on the nature of contacting materials, and on the presence of intermediate lubricant layers. What is the static coefficient of friction? The coefficient of […]
Who gave the best definition of economics?
Who gave the best definition of economics? Lionel Robbins (1932) developed implications of what has been termed “[p]erhaps the most commonly accepted current definition of the subject”: Economics is a science which studies human behaviour as a relationship between ends and scarce means which have alternative uses. What is economics and examples? Introduction to Economic […]
What is the density triangle?
What is the density triangle? The triangle is divided into three parts, with density occupying the top portion and mass and volume occupying the bottom two portions. The positions of each element of the triangle show us how they relate to one another through the formula above (Density = Mass / Volume, or ρ = […]
What is the importance of calibration?
What is the importance of calibration? Calibration is important because it helps assure accurate measurements and accurate measurements are required for most research, development, and innovation as well as safe and profitable production across virtually all industries of most products and services we use every day. What are the three main reasons for having an […]
What is the relation between magnetic field and current and distance?
What is psychology main focus?
What is psychology main focus? Neuropsychology is concerned with relationships between the brain and behavior. Neuropsychologists conduct evaluations to characterize behavioral and cognitive changes resulting from central nervous system disease or injury, like Parkinson’s disease or another movement disorder. What is the difference between a neurologist and a psychologist? Neurologists focused on those brain disorders […]

Answer is: mixing water and powdered drink mix, combining oil and vinegar to make salad dressing, diluting bleach with water and dinner spreading peanut butter on bread. Physical property can be observed and measured without any changes in molecular composition. Which of these is an […]
Which is one reason for the formation of global winds quizlet?
Which is one reason for the formation of global winds quizlet? Global winds are caused by the uneven heating of earth’s surface and the Coriolis. What are 2 examples of global winds? The four major wind systems are the Polar and Tropical Easterlies, the Prevailing Westerlies and the Intertropical Convergence Zone. These are also wind […]
Is frequency equal to intensity?
Is frequency equal to intensity? If intensity of a wave is proportional to frequency, why doesn’t sound level, in general, depend on frequency. i.e. Higher frequency, higher intensity, higher sound level. The loudness of a sound does not seem to depend on frequency. But according to the equation above, intensity DOES depend on frequency. How […]
