Does energy have momentum? Light indeed carries energy via its momentum despite having no mass. Public Domain Image, source: Christopher S. Baird. In the above equation, E is the total energy of the particle, p is the momentum of the particle (which is related to its motion), c is the speed of light, and m […]
What is the L quantum number?
Are combustion engines more efficient?
Are combustion engines more efficient? How efficient are engines? Combustion engines are stupefyingly inefficient. Most diesel engines do not even have a thermal efficiency of 50%. Of every gallon of diesel burned by a combustion engine, less than half of the energy generated becomes mechanical energy. How long will internal combustion engines be around? The […]
Can tsunamis be stopped?
Can tsunamis be stopped? Tsunamis could be stopped before they hit the coastline, a Welsh mathematician has proposed in a study of deep-ocean sound waves. Dr Usama Kadri, from Cardiff University’s School of Mathematics, has suggested that firing deep-ocean sound waves at an oncoming tsunami could save lives and reduce on-shore damage. What disaster will […]
What happens if you triple the distance between two objects?
What happens if you triple the distance between two objects? If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power). What is the formula of gravitational force? The mathematical formula […]
What is the formula of the salt formed by the reaction of aqueous phosphoric acid with aqueous potassium hydroxide?
What is the formula of the salt formed by the reaction of aqueous phosphoric acid with aqueous potassium hydroxide? How to Balance: H3PO4 + KOH = K3PO4 + H2O| Breslyn.org. What is the net ionic equation for potassium hydroxide and phosphoric acid? The net ionic equation for the reaction of aqueous solutions of phosphoric acid […]
Can atoms be broken down into smaller pieces?
Can atoms be broken down into smaller pieces? Under normal circumstances an atom can be broken down into any smaller particles, but we humans, have devised ways to break the atom apart. An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. How many atoms are […]
Why were Russian peasants so poor?
Why were Russian peasants so poor? The reforms in agricultural also disappointed the peasants. By 1900 around 85 per cent of the Russian people lived in the countryside and earned their living from agriculture. The nobility still owned the best land and the vast majority of peasants lived in extreme poverty. Why was there a […]
What are 3 uses of beryllium?
What are 3 uses of beryllium? Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites. Why is beryllium so expensive? Beryllium is […]
What coefficient is placed in front of O2?
What coefficient is placed in front of O2? The coefficient for O2 is 7. When C2H4 reacts with oxygen One product is water? When C2H4 reacts with oxygen, one product is water. Pentane (C5H12) reacts with oxygen (O2) to form carbon dioxide (CO2) and water (H2O) according to the following reaction. Answer the following question(s) […]
