Is it okay to cheat in exam? This will result in a much higher average performance than an in-person exam would, putting anyone who does not cheat at a disadvantage as any grading on a curve would hurt him or her. Cheating, being a form of dishonesty, is wrong even when rampant. Is it haram […]
What if we lived in a star cluster?
What if we lived in a star cluster? Inside a globular cluster, there might not be enough building materials for a rocky planet like Earth to be formed. Even our Sun might have had trouble forming in those conditions. Binary star systems aren’t unusual in the Universe, but they are less likely to host habitable […]
Does a rhombus have four 90 degree angles?
Does the crankshaft drive the transmission?
Does the crankshaft drive the transmission? The crankshaft only connects to the transmission when the car is in gear and the clutch is engaged. If you press down on the clutch the crankshaft disconnects from the transmission. The transmission is connected to the output shaft, which is connected to the axles, which are connected to […]
What is maximum spring potential energy?
What is maximum spring potential energy? 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. Where is maximum potential energy? You can see how the total energy is […]
When two phases are in equilibrium which is true?
When two phases are in equilibrium which is true? The basis for the rule (Atkins and de Paula, justification 6.1) is that equilibrium between phases places a constraint on the intensive variables. More rigorously, since the phases are in thermodynamic equilibrium with each other, the chemical potentials of the phases must be equal. What is […]
Why is geothermal energy not used?
Why is geothermal energy not used? Cons of geothermal energy: generates waste, reservoirs require proper management, it’s location-specific, has high initial cost, and can cause earthquakes in extreme cases. Geothermal has the potential to become a major global energy source, but is held back by its high upfront costs. Is Australia good for geothermal energy? […]
What is effect of temperature on solubility of gas in liquid?
What is effect of temperature on solubility of gas in liquid? Several factors affect the solubility of gases: one of these factors is temperature. In general, solubility of a gas in water will decrease with increasing temperature: colder water will be able to have more gas dissolved in it. What is the effect of temperature […]
What is horizontal motion formula?
Can we stop tectonic plates from moving?
Can we stop tectonic plates from moving? For tectonic plates to stop moving, the Earth’s mantle will have to be too cold for convection to occur. If that were to happen, then it means the Earth’s outer core has likely solidified. On one hand, if heat can’t reach the mantle or Earth’s crust, then the […]
