Where do light rays converge? A convex lens is also called a converging lens because it makes parallel light rays passing through it bend inward and meet (converge) at a spot just beyond the lens known as the focal point. Photo: A convex lens makes parallel light rays converge (come together) at the focal point […]
What happens if you add more product to a reaction?
What happens if you add more product to a reaction? According to Le Chatelier’s principle, adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products. If we add additional product to a system, the equilibrium will shift to the left, in order to produce more reactants. […]
Does white light absorb all colors?
Does white light absorb all colors? A white object reflects all colors of white light equally. If an object absorbs all colors but one, we see the color it does not absorb. The yellow strip in the following figure absorbs red, orange, green, blue, indigo and violet light. When a color is removed from white […]
Which two player positions are the only ones that can shoot?
Which two player positions are the only ones that can shoot? Goal Attack (GA) and Goal Shooter (GS) are the only players allowed to shoot and score goals. Shots must be taken within the shooting circle, sometimes referred to as the D or semi-circle. Can you bounce the ball off the post in netball? A […]
How is work related to internal energy?
How is work related to internal energy? The relationship between the internal energy of a system and its heat and work exchange with the surroundings is: E = q + w (The form of work will be restricted to gaseous, PV-type for this discussion.) Interestingly, both q and w are not state functions. What is […]
Which of these is an example of freshwater wetlands?
Which of these is an example of freshwater wetlands? Marshes, bogs, and lakes are examples of freshwater wetlands. Are all wetlands freshwater? Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish, or saltwater. The main wetland types are swamp, marsh, bog, and fen; sub-types include mangrove forest, carr, pocosin, floodplains, […]
Why is the sky orange and red at sunrise and sunset quizlet?
Why is the sky orange and red at sunrise and sunset quizlet? Why is the sky orange and red at sunrise and sunset? Gases absorb orange and red light. Blue wavelengths are absorbed by the atmosphere. The thick atmosphere scatters all but longer wavelengths. Why does the sun appear reddish early in the morning? During […]
What is topographic surface?
What is topographic surface? Surface topography is the local deviations of a surface from a perfectly flat plane. The topography of a surface is known to substantially affect the bulk properties of a material. Surface topography also known as surface texture, surface finish or surface profile. How do you mark a topographic map? The distinctive […]
What does anion mean?
What does anion mean? What is an anion? An anion has more electrons than protons, consequently giving it a net negative charge. For an anion to form, one or more electrons must be gained, typically pulled away from other atoms with a weaker affinity for them. Which atom is most likely to form a 1 […]
What is the overall charge of an ionic compound?
What is the overall charge of an ionic compound? The atoms in chemical compounds are held together by attractive electrostatic interactions known as chemical bonds. Ionic compounds contain positively and negatively charged ions in a ratio that results in an overall charge of zero. What is the overall charge for any compound? The overall or […]
