Why do we believe there is dark matter? A sufficiently massive and cold gas cloud can collapse under its own gravity to form stars. By contrast, dark matter cannot lose energy by emitting light. Thus, while conventional matter can collapse into dense objects like stars and planets, dark matter remains more diffuse. Does a parallel […]
How do you find the slope in a graph?
How do you find the slope in a graph? Using the Slope Equation Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or […]
Why do plants and animals depends on each other?
Why do plants and animals depends on each other? Complete Answer: A. Plants and animals depend on each other because in the ecological systems present on earth, it is impossible for any species to survive alone. Similarly, plants depend on animals for reasons like dispersal of fruits and seeds, pollination, and for the carbon dioxide […]
Which installation is not covered by the NEC?
Which installation is not covered by the NEC? The NEC does not cover electrical installations in ships, water- craft, railway rolling stock, aircraft, or automotive vehicles. What is the purpose of the NEC? The NEC (the National Fire Protection Association’s NFPA 70) is a widely-adopted model code for the installation of electrical components and systems. […]
Why past Cannot be changed?
Why past Cannot be changed? The past cannot be changed, the future is still in your power. Can God change the past? God can change the past, the present and the future. Nothing is beyond the Supreme Lord. He can change history and He can make history. In the Bhagavad Gita (BG), Lord Krishna says, […]
Why do we use resistors?
Why do we use resistors? A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. What causes resistors to burn? Blowing Up a […]
How much does a hovercraft cost?
How much does a hovercraft cost? Rescue hovercraft range from $28,000 to $79,000 and commercial hovercraft from $36,000 to $90,000. Trailers range from $3,000 to $12,600. (Prices in US Dollars.) HOW IS A HOVERCRAFT DIFFERENT FROM AN AIRBOAT? Why did they stop using hovercrafts? The Channel’s hovercraft service had its peak year in 198 when […]
How can standing waves be prevented?
How can standing waves be prevented? The solution to stopping a standing wave is cutting the offending frequency of the related instrument….Standing waves can be caused when waves bounce between; Opposite walls. Four sides of the room. All six sides of the room (given most rooms have four walls, a floor, and a ceiling!) Why […]
Can electrons travel through air?
Can electrons travel through air? In order to create an electrical current, electrons must be ripped off of the air molecules so that they are free to move and form a current. Rather, air displays a complex relationship between the applied voltage and the resulting electrical current traveling through the air. Can current flow in […]
How many H+ are pumped into the intermembrane space?
How many H+ are pumped into the intermembrane space? During the reduction of oxygen, two H+ ions are extracted from the matrix and transferred to the reduced oxygen atom, thus forming water (H2O). Simultaneously, the complex pumps 4 H+ ions into the intermembrane space. Is Complex 2 a proton pump? Complex II does not pump […]
