What is a example of transparent? Materials like air, water, and clear glass are called transparent. When light encounters transparent materials, almost all of it passes directly through them. Glass, for example, is transparent to all visible light. Can I apply honey daily on face? You can use honey as a spot treatment on scars, […]
What is the relation between temperature and kinetic energy?
What is the relation between temperature and kinetic energy? Temperature is directly proportional to the average translational kinetic energy of molecules in an ideal gas. How do speed of molecules kinetic energy and temperature of matter affect each other? If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. […]
What is the first law of thermodynamics in ecosystems?
What is the first law of thermodynamics in ecosystems? The first law of thermodynamics states that energy cannot be created or destroyed, only transformed; Energy enters an ecosystem as solar radiation, is conserved, and is lost from organisms as heat. Ecosystems are open systems, absorbing energy and mass and releasing heat and waste products. What […]
How did railroad companies encourage immigration?
How did railroad companies encourage immigration? Immigrants were not only integral to the construction of the transcontinental railroads that facilitated western expansion, but they also used the railroad to migrate west and to form new immigrant settlements in western states and territories. Why was the railroad so important to westward expansion? Impact on The United […]
Why do heat engines need to reject energy to environment?
Why do heat engines need to reject energy to environment? Expelling heat lets you get a positive area in your PV curve. This argument doesn’t apply to burning oil, because that’s not a cyclic process. In order to achieve this, the system dumps this extra gained entropy by giving off thermal energy to the cold […]
Is analog or digital better for sending large amounts of data?
Is analog or digital better for sending large amounts of data? Analog signals are composed of continuous waves that can have any values for frequency and amplitude. Digital signals are a more reliable form of transmitting information because an error in the amplitude or frequency value would have to be very large in order to […]
Which metal has highest fracture toughness?
Which metal has highest fracture toughness? Metals hold the highest values of fracture toughness….Material variation. Material type Material KIc (MPa · m1/2) Metal Aluminum alloy (7075) 20-35 Inconel 718 73-87 Maraging steel (200 Grade) 175 Steel alloy (4340) 50 Are ceramics tougher than metals? Ceramics tend to be much harder than commonly used metals. It […]
What energy is lost when a ball bounces?
What is the difference between global positioning system and geographic information system?
What is the difference between global positioning system and geographic information system? GPS stands for Global Positioning System. GPS uses satellites that orbit Earth to send information to GPS receivers that are on the ground. GIS is a software program that helps people use the information that is collected from the GPS satellites. What are […]
