What is r in ideal gas law? The factor “R” in the ideal gas law equation is known as the “gas constant”. R = PV. nT. The pressure times the volume of a gas divided by the number of moles and temperature of the gas is always equal to a constant number. How does Boyle’s […]

Are LED continuous or discrete? LED lights, or “Light Emitting Diodes,” as they are better known, emit a continuous spectrum. The spectrum they cover is not as broad as other colored lights or incandescent lights. How do you know if a variable is discrete? A discrete variable is a variable whose value is obtained by […]

What happens when a volume of fluid is warmed at the bottom? First, the liquid on the bottom of the pot closest to the heat source starts to get hot; as it does, it rises. The rising hot water is replaced by the cooler, more dense water molecules. The bubbles rise, due to buoyancy, and […]

What are the disadvantages of GMO Brainly? Answer: It can be dangerous to other insects that are important to our ecosystem. It sparks concerns on changing the field of agriculture. It can damage the environment. It causes unwanted residual effects. It can create more weeds. It threatens crop diversity. It has trade issues. Less Biodiversity. […]

What are the 4 components of a galaxy? From Earth, the Milky Way seems to be a heavenly mist because the stars blur together. Little do most people know, the stars are broken into four main parts. The four main parts are the disk, the nuclear bulge, the halo, and the galactic corona. What holds […]

What are the stages of reflection? Stages. The traditional stages of reflection are self-awareness, description, critical analysis, synthesis, and evaluation. This is the cognitive model of learning by reflection. What are the reflective models? One of the most famous cyclical models of reflection leading you through six stages exploring an experience: description, feelings, evaluation, analysis, […]

Can tires lose pressure without caps? It’s not uncommon for valve stem caps to fall off. While a missing valve stem cap may seem harmless, it can lead to loss of air pressure. Without a cap, dirt and debris will enter the valve stem where it can break through the seal. When this occurs, air […]

Do we see with our eyes or brain? Our eyes do a really good job of capturing light from objects around us and transforming that into information used by our brains, but our eyes don’t actually “see” anything. That part is done by our visual cortex. Our eyes being slightly apart creates an image that […]

How do you find maximum velocity? Using Calculus If acceleration is positive to the left and negative to the right, the point is a maximum velocity. In the example, a=3cos(t) is positive just before t=π /2 and negative just after, so it is a maximum; however, 3π/2 is a minimum because a=3cos(t) is negative just […]

How long does it take a star to return to the same position in the sky as it was the night before? about 24 hours Can you see the same stars in both hemispheres? Constellations such as Orion may be seen in both hemispheres, depending on your distance from the equator and the time of […]
