What is intensity in black body radiation? The intensity (or flux) at all wavelengths increases as the temperature of the blackbody increases. Although the intensity may be very low at very short or long wavelengths, at any temperature above absolute zero energy is theoretically emitted at all wavelengths (the blackbody radiation curves never reach zero). […]

Why is there no life on Jupiter? Jupiter’s environment is probably not conducive to life as we know it. The temperatures, […]
Why are the energy levels for hydrogen and helium not identical?
Why are the energy levels for hydrogen and helium not identical? Hydrogen and helium illustrate the fact that not all atoms have the same properties. Helium atoms, on the other hand, have two protons and two electrons in the lowest energy level. The lowest energy level is filled with its maximum number of electrons. How […]
How does living near an ocean affect the climate?
How does living near an ocean affect the climate? Large bodies of water, such as oceans, seas and large lakes, can affect the climate of an area. Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with […]
What is a velocity chart in Jira?
What is a velocity chart in Jira? The Velocity Chart shows the amount of value delivered in each sprint, enabling you to predict the amount of work the team can get done in future sprints. It is useful during your sprint planning meetings, to help you decide how much work you can feasibly commit to. […]
How can you separate salt from water without heat?
How can you separate salt from water without heat? The most common type of membrane separation is called reverse osmosis. Seawater is forced through a semipermeable membrane that separates salt from water. Because the technology typically requires less energy than thermal distillation, most new plants, like Tampa’s, now use reverse osmosis. Can you drink sea […]
Do push-ups increase strength?
Do push-ups increase strength? Traditional pushups are beneficial for building upper body strength. They work the triceps, pectoral muscles, and shoulders. When done with proper form, they can also strengthen the lower back and core by engaging (pulling in) the abdominal muscles. Pushups are a fast and effective exercise for building strength. Can I do […]
How do we know electrons exist?
How do we know electrons exist? The British physicist who discovered electrons, JJ Thomson, used a particularly eye-catching method to prove their existence in 1897. His special device was called a Crookes tube – a funny shaped piece of glass out of which nearly all the air was sucked by a machine. Is an electron […]
