What is the average kinetic energy of any substance at 0 K J? 0 Kelvin is the temperature where the is no kinetic energy, so the answer is 0. When the kinetic energy of particles in a substance decreases will also decreases? When the kinetic energy of particles in a substance decreases, what also decreases? […]

Can there be fog when it rains? Precipitation Fog: This is fog that forms when rain is falling through cold air. This is common with a warm fronts but it can occur with cold fronts as well only if it’s not moving too fast. Cold air, dry at the surface while rain is falling through […]

Can adult bone bend? Children’s bones can actually bend before they break. An adult bone is […]

What is a scaled vector? It is associated with a numerical value. In vector diagrams, the length of the vector arrow represents the magnitude of the vector quantity. Scale. Vector diagrams utilize a scale to help represent the magnitude. A scale indicates the ratio of the distance on a map to the actual distance along […]

What are 3 facts about the outer core? The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth’s magnetic field. As Earth spins […]

What happens to the length of the spring when the key is pressed? So now that they have pressed the key, the key’s gone down by 4.8 millimeters. In other words, that’s how much the spring is compressed by. And this happens every time you press a key on the keyboard. When a key is […]

Why Studying is so boring? It didn’t want to learn those things which it think as not important and thus we don’t have any interest, so it becomes boring and tedious. Doing work more than our capacity can exhaust us and and this same principle applies to our brain. Our brain also requires some rest […]

What are the factors that affect the amount of solar radiation? In total seven influences on solar radiation have been identified: Solar elevation. Where the sun sits in the sky determines the level of UV radiation reaching us. Ozone. Cloud cover. Ground surface reflectivity. Altitude. Aerosols and pollutants. Direct and diffuse UV. What factors affect […]
