Then, the potential energy from the strong nuclear force causes the two nuclei to 'fall into' each other by converting the potential energy into kinetic energy (doing work). They then fuse into one nuclei. The residual output kinetic energy is then the 'released energy' from the process and...
How does the rest mass of an object turn into energy? Rest mass cannot turn into energy. What is rest mass? Loosely speaking, mass is the inertia of an object, force divided by acceleration. It turns out, inertia of an object is exactly proportional to energy. Isn't that what E=mc2E...
All the waves have to be identical when they leave the laser. Here's what happens when you turn on a laser to expose a holographic plate: A column of light leaves the laser and passes through the beam splitter. The two columns reflect off of their respective mirrors and pass through ...
Whether your body is quick or slow to change the food you eat into energy depends on your genes. And although some people don’t have an issue burning calories even at rest, some may find it extremely difficult. Unfortunately, you can’t change your genes; however, you can incorporate oth...
record and the ensuing tsunami inflicted serious damage on the plant and several of its reactor units. Among other events, water drained from the reactor core, which in turn made it impossible to control core temperatures. This resulted in overheating and a partial nuclear meltdown [source:NPR]...
How to Generate Electricity with Geothermal Energy Geothermal energy is energy from within the earth. The earth from inside is too hot. This heat from within the earth can be used to turn turbines and produce electricity. This technology is still a subject matter of further research and engineer...
One International Journal of Obesity study found that 20-minute HIIT workouts helped women lose 5.5 more pounds and gain more lean muscle mass over the course of 15 weeks than women who did long, steady cardio workouts. At the gym, sign up for a HIIT class, or turn your favorite aerobic...
A light wave consists of electromagnetic energy. The size of a wave is measured by its wavelength. The wavelengths of the light we can see range from 400 to 700 billionths of a meter (nanometers). The amount of energy in a light wave is proportionally related to its wavelength: shorter ...
Light can be separated into different wavelengths, which we can see in the form of a rainbow. Since the light that hits our cell has photons of a wide range of energies, it turns out that some of them won't have enough energy to alter an electron-hole pair. They'll simply pass ...
How to deal with climate change and global warming, including disaster planning, wildfires, flooding, sea level rise. Consumer guides for reducing energy use, reducing consumption, reuse, recycling, solar and EV buying guides.
