How does sensation affect learning?
How does sensation affect learning? Sensation and perception work together through a processes that allows one to take in information from environmental stimuli and transfer it into data, which the brain and body use to modify behavior (“Saylor.org”, 2012). Sensation and perception effect the way one learns through one’s interpretation of information. What is sensation […]
Is energy stored in a resistor?
Is energy stored in a resistor? Power in Resistors. When a current flows through a resistor, electrical energy is converted into HEAT energy. The heat generated in the components of a circuit, all of which possess at least some resistance, is dissipated into the air around the components. What are the five elements needed for […]
How is sound defined in science?
How is sound defined in science? In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. Sound waves below 20 Hz are known as […]

What do you understand by angle of shear?
What do you understand by angle of shear? The angle between the planes of maximum shear, which is bisected by the axis of greatest compression. What is shear angle in cutting tool? In orthogonal cutting, shear angle is the angle between (a) shear plane and the cutting velocity. (b) shear plane and the rake plane. […]
What did oil drop experiment prove?
What did oil drop experiment prove? Explanation: Millikan’s oil drop experiment proved that electric charge is quantized. This was the big result of the oil drop experiment. That he could also determine the charge of the electron was a secondary benefit. What oil did Millikan use? vacuum pump oil What oil was used in Millikan […]
What are the 4 major crime labs?
What are the 4 major crime labs? These four major federal crime labs help investigate and enforce criminal laws beyond the jurisdictional boundaries of state and local forces: FBI (Federal Bureau of Investigation), DEA (Drug Enforcement Agency), Bureau of Alcohol, Tobacco, Firearms and Explosives, and U.S. Postal Inspection Service.

Why do mirrors in reflecting telescopes need parabolic mirrors?
Why do mirrors in reflecting telescopes need parabolic mirrors? Reflecting telescopes have many advantages over refracting telescopes. Mirrors don’t cause chromatic aberration and they are easier and cheaper to build large. Different reflectors use different shapes of mirrors. Parabolic mirrors will focus all incoming light rays to a single point. Which is better reflector or […]
