Boyle’s law states that the volume of a given mass of gas varies inversely with the pressure when the temperature is kept constant. … An increase in pressure pushes the molecules closer together, reducing the volume. If the pressure is decreased, the gases are free to move about in aRead More →
Summary. A neurological itch (a.k.a. neuropathic itch) is caused by injury to nerve fibers in the brain, spinal cord, skin, or other parts of the body. Unlike many other types of itch, neuropathic itches often involve nerve pain and often get more intense the more you scratch. Is itching aRead More →
Postherpetic neuralgia (post-hur-PET-ik noo-RAL-juh) is the most common complication of shingles. The condition affects nerve fibers and skin, causing burning pain that lasts long after the rash and blisters of shingles disappear. The chickenpox (herpes zoster) virus causes shingles. Can shingles pain go away and come back? In very rareRead More →
When a ray of light passes from one medium to the other medium, the physical quantities related with this ray of light such as velocity, wavelength, amplitude, etc changes such that the frequency of the wave always remains the same. Therefore, the frequency of the light does not change onRead More →
Students calculate the rate of change also know as the constant of proportionality (k = y/x) which is the constant ratio between two proportional quantities y/x denoted by the symbol k which may be a positive rational number. The x value is directly proportional to the y value such asRead More →
The improved Energizer MAX® batteries last up to 30 percent longer than previous Energizer MAX® AA batteries in digital cameras, giving consumers the power to do more of what they love. Do Energizer Max last longer than Duracell? Both manufacturers have NiMH (Nickel-metal hydride) rechargeable batteries. … The results showedRead More →
In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the speed might be constant. … Acceleration is in the direction of the change in velocity, which points directly toward the center of rotation—the center of the circular path. WhichRead More →
