What is the similarities between magnetism and gravity? Gravity is a force acting on an object with mass, magnetism is a force exerted by virtue of charged particles. Both are based on ferrous material, one is created by mas the other by the movement of the mass. Why is gravitational force a non contact force? […]

Can a stationary charge experiences a magnetic force?
Can a stationary charge experiences a magnetic force? There is no magnetic force on static charges. However, there is a magnetic force on moving charges. When charges are stationary, their electric fields do not affect magnets. But, when charges move, they produce magnetic fields that exert forces on other magnets. Why is a stationary charge […]
How do you add a function?
How do you add a function? Operations on Functions: Adding and Subtracting Functions Addition. We can add two functions as: (f + g)(x) = f(x) + g(x) Example: Subtraction. We can subtract two functions as: (f – g)(x) = f(x) – g(x) Example: Multiplication. (f•g)(x) = f(x)•g(x) Example: f(x) = 3x – 5 and g(x) […]
Which unit is used to measure the speed of computer?
Which unit is used to measure the speed of computer? Clock speed is measured in units of cycles per second, which is called a Hertz (Hz). Computer boards and CPUs run at rates of millions and billions of Hertz, megahertz (MHz) and gigahertz (GHz). What unit is typically used to measure the speed of a […]

What is spectrophotometer and its uses?
What is spectrophotometer and its uses? A spectrophotometer is an analytical instrument used to quantitatively measure the transmission or reflection of visible light, UV light or infrared light. Applications for specs include measurement of substance concentration such as protein, DNA or RNA, growth of bacterial cells, and enzymatic reactions. What is spectroscopy principle? What Is […]
How do you determine if there is a hydraulic jump?
How do you determine if there is a hydraulic jump? A hydraulic jump occurs when the upstream flow is supercritical (F>1). To have a jump, there must be a flow impediment downstream. The downstream impediment could be a weir, a bridge abutment, a dam, or simply channel friction. Water depth increases during a hydraulic jump […]
What is oxygenated blood called?
What is oxygenated blood called? Oxygenated blood is also called arterial blood as the arteries deliver oxygenated blood to different parts of the body through the pulmonary veins. Where does oxygenated blood come from? Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where […]
