How hard is it to push a car uphill? If you have a winch or a tow-strap (and a friend to pull your car with said tow-strap) then you’d be in business, but pushing any car up an incline in the dry is virtually impossible (it takes effort to move a car even on a […]

How do you calculate the pressure at the bottom of a container? Its bottom supports the weight of the fluid in it. Let us calculate the pressure exerted on the bottom by the weight of the fluid. That pressure is the weight of the fluid mg divided by the area A supporting it (the area […]

How are RC circuits used in real life? The RC circuit has thousands of uses and is a very important circuit to study. Not only can it be used to time circuits, it can also be used to filter out unwanted frequencies in a circuit and used in power supplies, like the one for your […]

How do you write a research question example? All research questions should be: Focused on a single problem or issue. Researchable using primary and/or secondary sources. Feasible to answer within the timeframe and practical constraints. Specific enough to answer thoroughly. Complex enough to develop the answer over the space of a paper or thesis. What […]

Group therapy for families is an example of a humanistic approach. How do you become a humanistic […]

Is y equal to dy dx? Yes, as long as x is the variable you are differentiating with respect to. For example, if your function is y = 3x 2 + 5x, then both y′ and dy/dx refer to the derivative of this function with respect to x, which is 6x + 5. What is […]

What is another name for NaCl? Sodium chloride /ˌsoʊdiəm ˈklɔːraɪd/, commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. Which is another word for sodium *? What is another word for sodium chloride? NaCl […]

What is primary frequency response? Primary Frequency Response are actions to arrest and stabilize frequency in response to frequency deviations. Primary Response comes from generator governor response, load response (motors) and other devices that provide immediate response based on local (device- level) control. What is primary frequency control? – The Primary Frequency Control (PFC), an […]

What happened Apollo 10 Snoopy? After Apollo 9 tested the lunar module in space for the first time in Earth orbit, Apollo 10 acted as a dress rehearsal for the Moon landing. Unlike in the five missions that landed on the Moon, the Snoopy lunar module was ultimately jettisoned into an orbit around the Sun. […]

What major events happened during the Triassic period? The start of the Triassic period (and the Mesozoic era) was a desolate time in Earth’s history. Something—a bout of violent volcanic eruptions, climate change, or perhaps a fatal run-in with a comet or asteroid—had triggered the extinction of more than 90 percent of Earth’s species. What […]
