Can you use a transistor as a diode? Since a bipolar transistor is essentially two diodes, it can function as such. However, since bipolar transistors are not designed to be used as diodes, using them as diodes might cause a problem in terms of current and other ratings. Use dedicated diodes for typical diode applications […]
Can you predict the path of a tornado?
Can you predict the path of a tornado? The precise tracking and prediction of tornadoes is not yet a reality. Meteorologists can identify conditions that are likely to lead to severe storms. They can use radar to track the path of thunderstorms that might produce tornadoes. … How fast can a tornado be detected? Phased […]
What happens when resistance is connected in parallel?
What happens when resistance is connected in parallel? When resistors are connected in parallel, more current flows from the source than would flow for any of them individually, so the total resistance is lower. Each resistor in parallel has the same full voltage of the source applied to it, but divide the total current amongst […]
Why is my popcorn not popping?
Why is my popcorn not popping? Popcorn doesn’t pop, not because it’s too wet, but because it’s too dry. The popcorn’s pop is caused by moisture inside the kernel heating up and creating steam. When there’s not enough moisture, there’s not a good pop. Can you Repop popcorn that didn’t pop? It’s important to keep […]
What are four ways of increasing the efficiency of a Rankine Cycle?
What are four ways of increasing the efficiency of a Rankine Cycle? There are three ways to increase the efficiency of the simple ideal Rankine cycle. Decreasing the condenser pressure. The effect of lowering the condenser pressure on the Rankine cycle efficiency is illustrated on a T-s diagram on the left. Superheating the steam to […]
Why is there 60 minutes in an hour and not 100?
Why is there 60 minutes in an hour and not 100? The Babylonians made astronomical calculations in the sexagesimal (base 60) system they inherited from the Sumerians, who developed it around 2000 B.C. Although it is unknown why 60 was chosen, it is notably convenient for expressing fractions, since 60 is the smallest number divisible […]
What happens when you change the frequency of a light wave?
What happens when you change the frequency of a light wave? Explanation: Since light travels at the speed of light (wow), if you increase the frequency (number of waves per time frame) then you have to decrease the length of those waves in order to maintain the speed. What is the lowest frequency of light? […]
What would happen if all the sea ice melted?
What would happen if all the sea ice melted? If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. But many cities, such as […]
How many balloons would it take to lift a human?
How many balloons would it take to lift a human? This would require a balloon with about a 15.5 foot diameter. If instead you used small spherical (one foot diameter) balloons (which holds about 0.526 cubic feet of gas), it would take over 2754 of them to lift the 100 pounds. Therefore a handful of […]
What molecule has the most free energy?
What molecule has the most free energy? ATP What are basic metabolic pathways? In humans, the most important metabolic pathways are: glycolysis – glucose oxidation in order to obtain ATP. citric acid cycle (Krebs’ cycle) – acetyl-CoA oxidation in order to obtain GTP and valuable intermediates. oxidative phosphorylation – disposal of the electrons released by […]
