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 […]

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 […]

What will happen to blood cell If valves are not present? When the pulmonary valve is missing or does not work well, blood does not flow efficiently to the lungs to get enough oxygen. In most cases, there is also a hole between the left and right ventricles of the heart (ventricular septal defect). This […]

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 […]

When light falls on Prism The result can be? When light falls on a prism the result can be magnification. Why a glass prism disperses white light? -When the ray of light enters from the air medium into the glass medium of the glass slab, the refraction (bending) of the light must occurs due to […]

Can bones bend over time? Bones can change their shape throughout our life by regulating bone formation and resorption processes, which is often a response to forces which press, pull and twist the skeleton during everyday movements and exercise. Can adult bone bend? Children’s bones can actually bend before they break. An adult bone is […]

Is magnitude and distance the same? Distance is defined to be the magnitude or size of displacement between two positions. How do you find the magnitude and distance? The magnitude of a vector →PQ is the distance between the initial point P and the end point Q . In symbols the magnitude of →PQ is […]
