What element is a good insulator? Examples of good conductors are sliver, tin, and lead. Good insulators contain 8 electrons which mean they are stable(noble gasses group 18). Insulators can’t be easily transported from one atom to another and nonmetals make good insulators. Three examples of good insulators are sulfur, silicon, and rubber. What makes […]
At what angle a player should throw a javelin to achieve maximum range?
What happens if centrifuge is not balanced?
What happens if centrifuge is not balanced? Centrifuges, which operate at high speed, have great potential for injuring users if not operated properly. Unbalanced centrifuge rotors can result in injury or death. Sample container breakage can release aerosols that are harmful if inhaled. What is the principle of centrifuge? A centrifuge works by using the […]
Why diffusion is faster in water?
Why diffusion is faster in water? This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. Because diffusion happens from high concentration to low concentration, the more molecules are moving, the more opportunities they have to mix together. What is the slowest diffusing […]
Is flow rate a vector?
Is flow rate a vector? 1 Velocity, speed, flow rate, and acceleration. Velocity indicates the distance and the direction of a motion, and is called a vector quantity. To define a vector quantity, both magnitude and direction are needed. What is the unit of flow rate? In S.I. units (International System of Units), volume flow […]
Why is the electric field of dipole not zero?
Why is the electric field of dipole not zero? Why is electric field of dipole nonzero? Because the positive and the negative charges are separated by some distance. So though the a Gaussian surface enclosing the electric dipole has zero net charge the electric field in the region isn’t zero because there are separated charges […]

Is thermal energy the total kinetic energy of an object?
Is thermal energy the total kinetic energy of an object? Thermal energy is the total internal kinetic energy of an object due to the random motion of its atoms and molecules. It is sometimes confused with internal energy or thermodynamic energy. They consist of the sum of the internal kinetic energy (thermal energy) and the […]
How many protons and electrons are in oxygen?
How many protons and electrons are in oxygen? 8 Is the number of nucleons equal to the number of electrons? The atomic number gives the number of protons in the atom. The number of nucleons gives the total number of protons plus neutrons in the atom. Since an atom is electrically neutral, an atom has […]
