What are the causes of convection current? Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. Where can convection currents […]
Is a woodchuck and a beaver the same thing?
Is a woodchuck and a beaver the same thing? The woodchuck and the beaver belong to the same rodent species, and are closely related to the squirrel family. Though they exhibit certain resemblance like the ever-growing teeth, gnawing habits, and ability to regulate temperature, there are a lot of differences in their habitats, breeding and […]
How do I increase the resolution of my GC?
How do I increase the resolution of my GC? To improve the resolution of earlier eluting peaks, decrease the initial temperature or increase the initial hold time. Decreasing the initial temperature usually results in the largest resolution improvement, but analysis times are substantially increased (Figure 32a). What affects resolution in GC? Changes in resolution are […]
What is the maximum potential energy of the spring?
What is the maximum potential energy of the spring? When the kinetic energy is maximum, the potential energy is zero. This occurs when the velocity is maximum and the mass is at the equilibrium position. The potential energy is maximum when the speed is zero. What is the potential energy of a spring derive it? […]

What element has 2 protons 2 neutrons?
What element has 2 protons 2 neutrons? Helium What did Chadwick prove? In 1932, Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons – elementary particles devoid of any electrical charge. For this epoch-making discovery he was awarded the Hughes Medal of the Royal Society in 1932, […]
What would happen if there was no cryosphere?
What would happen if there was no cryosphere? In the Arctic, the decline of the cryosphere is affecting fundamental biological cycles like the reproduction of carbon-storing plankton. And it may also be affecting the jet stream, making weather more extreme across the Northern Hemisphere. Will there be another ice age? Researchers used data on Earth’s […]
How do you turn on a blind intersection?
How do you turn on a blind intersection? What should you do in a Blind Intersection? In such a scenario, you should inch forward slowly until you can see clearly to cross the intersection. Once clear, you can continue as normal. However, by crossing slowly, you can quickly stop if another car comes into the […]
How much is a printed circuit board?
How much is a printed circuit board? Printed circuit boards have a huge range of quality, reliability, complexity, and price points. A circuit board typically costs from 50 cents to $300 dollars to produce, depending on your needs. What is the other name of printed circuit board? PCBs use conductive pathways, tracks or signal traces […]
