What is the L quantum number? The angular quantum number (l) describes the shape of the orbital. Orbitals have shapes that are best described as spherical (l = 0), polar (l = 1), or cloverleaf (l = 2). They can even take on more complex shapes as the value of the angular quantum number becomes […]
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 […]
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 […]
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 […]
Does energy have momentum?
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 net ionic equation for potassium hydroxide and phosphoric acid? The net ionic equation for the reaction of aqueous solutions of phosphoric acid […]
What part of Japan is safe from tsunami?
What part of Japan is safe from tsunami? Sendai How dangerous is Japan? Crime. Although Japan is considered a very safe destination for tourists, you should still use your common sense to avoid trouble. We recommend a few simple precautions to keep you safe on your travels: Avoid going out by yourself at night to […]
What is the main purpose of capacitor?
What is the main purpose of capacitor? Capacitors are widely used in electronic circuits for blocking direct current while allowing alternating current to pass. In analog filter networks, they smooth the output of power supplies. In resonant circuits they tune radios to particular frequencies. What is the importance of capacitor? Capacitors have many important applications. […]
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 […]
How do I calculate my daily energy consumption?
How do I calculate my daily energy consumption? Once you have those three bits of info, here’s how to calculate the cost: Calculate the daily energy consumption: (Wattage) x (hours used per day) Divide the answer by 1,000. Calculate the annual use: (Daily energy consumption) x (number of days the appliance is used per year) […]
