What happens when a big star collapses? The outer layers of the star will be ejected into space in a supernova explosion, leaving behind a collapsed star called a neutron star. Ordinary matter, the kind that we and everything around us is made of, is mostly empty. It is made up of atoms, which are […]
Why is sediment transport important?
Why is sediment transport important? Sediment transport is applied to solve many environmental, geotechnical, and geological problems. Measuring or quantifying sediment transport or erosion is therefore important for coastal engineering. Movement of sediment is important in providing habitat for fish and other organisms in rivers. What are two ways water transports sediment? How do rivers […]
What percentage of C 14 remains after 3 half lives?
Who wins the tug of war with what net force?
Are any goods perfectly elastic?
Are any goods perfectly elastic? If demand is perfectly elastic, it means that at a certain price demand is infinite (A good with a very high elasticity of demand). In other words, if a firm increased the price by 1%, it would see all its demand evaporate. Is coffee elastic or inelastic? Availability of Substitutes […]
Do tents attract lightning?
Do tents attract lightning? Tents alone don’t attract lightning, but that doesn’t mean they’re safe during a thunderstorm. The possibility for a tent to get struck by lightning is increased by the campsite location and adjacent tall objects. What happens if lightning hits a tent? If a lightning bolt hits a tent the energy will […]
What role does carbon dioxide play in photosynthesis?
What role does carbon dioxide play in photosynthesis? The carbon dioxide enters the leaves of the plant through small pores called stomata. The plant uses sunlight as energy to perform this chemical reaction. Photosynthesis separates carbon dioxide and water — known as CO2 and H2O, respectively — into their individual molecules and combines them into […]
Why do toilets flush the opposite way in Australia?
Why do toilets flush the opposite way in Australia? Because of the rotation of the Earth, the Coriolis effect means that hurricanes and other giant storm systems swirl counter-clockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere. In theory, the draining water in a toilet bowl (or a bathtub, or any vessel) should […]
Can 2 remote control cars same frequency?
Can 2 remote control cars same frequency? If you don’t plan to run your RC cars, trucks, boats, or aircraft alongside other radio controlled vehicles, it doesn’t really matter which frequency they use. However, running two 27MHz or two 49MHz RC cars near each other will usually result in interference—crosstalk. The radio signals get mixed […]
What is the difference between 6ka and 10kA MCB?
What is the difference between 6ka and 10kA MCB? The main difference between the two is their capacity, with the MCB rated under 100 amps with an interrupting rating of under 18,000 amps. How do you calculate kA rating? The maximum amount of current that can flow through a circuit is determined by the size […]
