- (1) 39. Flotation is a method to determine the __ of a particle of glass temperature refractive index density weight
- 9. How much power does a person weighing 500 N need to climb a 3-m ladder in 5 seconds? 10.How much power is needed to hammer in a nail when you apply 300 N of force and the nail moves a distance of 5 cm?(The hammer is nailed in 34 seconds)
- D. 36. What is the definition of REFRACTION? a. A hard, amorphous transparent material made by heating a mixture of sand and other additives b. The change in direction of light as it changes speed when moving from one substance into another c. Without shape or form; applied to glass,it refers to having particles that are arranged random instead of with a definite pattern d. Aratio of the mass of an object to its volume e. The chemical formula for silica (SiO_(2)) a b o e Di) d
- For the Flow Tab:(In this simulation, the flow rate out of the pipe at the left end is kept at a constant value shown in the box in the upper left corner.) 1. With the friction box unchecked, check the box for flux meter to place a flux meter in the middle of the pipe. Move the speed gauge to different locations inside the pipe to take speed reading. What do you find from the speed gauge? __ Now use a handle in the middle to make the pipe narrower in the middle. Record the readings of the flux meter: Flow rate: __ , area: __ - (flux: Ignore this reading and the way "flux "is used in this simulation because the term"flux"can be ambiguous.). Which of these quantities stayed the same when you change the size of the pipe and why?Please also move the speed gauge around to see how the speed varies at different locations inside the pipe. __ 3. What do you think will happen qualitatively to these 2 readings of the flux meter if you use a handle in the middle to make the pipe wider in the middle? Flow rate: Do the actual reading match your expectations? __ , area: __ se around to see how the speed varies Please also move the speed gauge at different locations inside the pipe. Briefly write down your observations.
- Do 31. What is the definition of RADIAL FRACTURE? a. Acrack in the glass that extends outward like a spoke of a wheel from the point at which the glass was struck. b. The line created as the refracted light becomes concentrated around the edges of the glass fragment c. Ameasure of how light bends as it passes from one substance to another d. Acrack in the glass that forms a rough circle around the point of impact Do) C Do) d Do) b Do)
