What is the coating on the inside of a light bulb? The white powder coating inside the glass tubing of a CFL contains a fluorescent coating. When electricity enters a CFL, mercury and argon fumes inside the bulb produce invisible ultraviolet (UV) light. This UV light reacts with the fluorescent coating to produce the white, […]
When a slab of dielectric medium is placed between plates of a parallel plate capacitor which is connected with a battery then the charge on plates in comparison with earlier charge?
When a slab of dielectric medium is placed between plates of a parallel plate capacitor which is connected with a battery then the charge on plates in comparison with earlier charge? Two identical capacitors are connected as shown in the figure. A dielectric slab is introduced between the plates of one of the capacitors so […]
What does it mean when a nucleus is stable?
What does it mean when a nucleus is stable? Definition. Nuclear stability means that the nucleus of an element is stable and thus it does not decay spontaneously emitting any kind of radioactivity. Those nuclei with the highest binding energy per nucleon are the most stable with respect to destructive nuclear reactions. What is the […]

What is the direction of magnetic field in a bar magnet?
What is the direction of magnetic field in a bar magnet? Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the […]
How do you set up dimensional analysis problems?
How do you set up dimensional analysis problems? Set up each problem by writing down what you need to find with a question mark. Then set it equal to the information that you are given. The problem is solved by multiplying the given data and its units by the appropriate unit factors so that only […]
What enzymes do lysosomes contain?
What enzymes do lysosomes contain? Lysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. Lysosomal enzymes are synthesized in the endoplasmic reticulum (ER), are transported to the Golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label. What organelle is responsible for respiration? The “powerhouses” of the […]
What does 9 10 look like as a decimal?
How many coordinate systems are there?
How many coordinate systems are there? In this article we mainly discuss two types of coordinate systems. What is the difference between phi and theta? Theta is the same as the angle used in polar coordinates. Phi is the angle between the z-axis and the line connecting the origin and the point. How do you […]
What is the balancing?
What is the balancing? A state of equilibrium or parity characterized by cancellation of all forces by equal opposing forces. 3. The power or means to decide: matters that fell outside the judge’s balance. What are different types of balancing? There are three different types of balance: Symmetrical, asymmetrical and radial. What are the 4 […]
