What are the 2 types of mass? In classical mechanics, there are three types of mass or properties called mass: Inertial mass; passive gravitational mass; and active gravitational mass. Where do we use mass in everyday life? Another example of everyday use is mass producing a recipe. Say you are making an extremely large cake […]

How long can you drive with brake light on? It is safe to drive with this light on for a short amount of time. As mentioned earlier, the light will come on when you still have some brake pad material left, but if you wait too long and continue driving, you will run out of […]

What are all the types of energy when a bullet is fired? A bullet stores chemical potential energy in its gunpowder. When the bullet is fired, this chemical energy is converted into kinetic energy and heat. When a gun is fired Why does the bullet have more energy than the gun? So a simple mass […]

What are the 3 magnetic materials? Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone. Does the human […]

Do pilots pee while flying? Piddle Packs are small bags male fighter pilots use to pee while in flight. They are specially shaped bags with absorbent beads in them. If we have to relieve ourselves, we’ll unzip the flight suit—which is designed to unzip from the top as well as the bottom—unroll the piddle pack, […]

What are the applications of DNA sequencing? Homologous DNA sequences from different organisms can be compared for evolutionary analysis between species or populations. Notably, DNA sequencing can reveal changes in a gene that may cause a disease. DNA sequencing has been used in medicine including diagnosis and treatment of diseases and epidemiology studies. What are […]

What is a secondary motion? Secondary animation also known as secondary motion, is used to refer to flat motions that are generated as a reaction to the movement of primary motion by a character. Examples of secondary motion include the rippling of water, swish of a cloak, or jiggle of body parts when a person […]

What are examples of chemical hazards? Some commonly used workplace chemical hazards include: Acids. Caustic substances. Cleaning products such as toilet cleaners, disinfectants, mildew remover and chlorine bleach. Glues. Heavy metals, including mercury, lead, cadmium, and aluminum. Paint. Pesticides. Petroleum products. How do you identify chemical hazards? To identify if a substance is hazardous, check […]

When an electron makes a transition from the N 4 to the N 2 then emitted line spectrum will be? Explanation: Jump to second orbit leads to Balmer series. The jump from 4th orbit shall give rise to second line of Balmer series. When an electron in hydrogen atom is excited? When an electron in […]

How dangerous is spearfishing? With Spearfishing you may encounter a variety of dangers including Sharks, shallow water blackout, heavy seas, strong currents, Jelly Fish, and risk drowning as a result fo line tangles. Spearfishing by its very nature is an extreme sport and few activities can rival the excitement and thrill of landing a quality […]
