What is better a generator or inverter? Conventional portable generators are able to produce more power than inverter generators. This has to do with a number of factors including the size of the fuel tank and the mechanical difference in electricity production. Inverter generators are more energy efficient thanks to how the final AC current […]

What is the relation between current and intensity? This current is the number of electrons being emitted per second. That is directly proportional to the intensity of the light. So greater intensity means more photons striking the surface and hence an increase in the emitted electrons. The frequency of the light tells is about the […]

Does rubber neutralize electricity? Rubber is an insulator. Electricity will always travel “the path of least resistance.” Rubber has a very high resistance, so electricity will go somewhere else to find ground. It doesn’t neutralize electricity. It has a high electrical resistance, making it very difficult for electricity to pass through it. Can insulators prevent […]

Why would a researcher interested in making a casual claim not do an experiment? Why would a researcher interested in making a causal claim NOT do an experiment? There may be ethical limitations of manipulating a variable. Why is the statistical validity of a multiple regression design more complicated to interrogate than a bivariate design? […]

What is the meaning of narrow leaves? Narrow-leaf bedstraw (Galium angustifolium) is a small, multi-stemmed shrub that may grow alone but often scrambles through the branches of larger plants. The stems are four-sided, usually ridged. Leaves are linear, less than 1 inch (2.5 cm) in length, with a small point at the tip. Petioles are […]

What happens to a wave when it reaches a barrier? Diffraction: A wave encountering a small obstacle tends to bend around the obstacle. This bending of the wavefront is called diffraction. When a wave encounters a barrier with an aperture, which is much smaller than the wavelength, the wave bends and spreads out as a […]

What is ionized helium? Singly ionized helium is an atom that has lost one of its electrons. We must expect its remaining electron to act like a hydrogen electron. There is only one difference between a hydrogen atom and a singly ionized helium atom; number of protons in the nucleus, so the nuclear charge. What […]

Is force a base quantity? The SI is founded on seven SI base units for seven base quantities assumed to be mutually independent, as given in Table 1…. Derived quantity force Name newton Symbol N Expression in terms of other SI units – Expression in terms of SI base units m·kg·s-2 Is speed a fundamental […]

What can you not do after stem cell injections? Avoid any forceful rotation or manual manipulation. Remember that good healing during the first two months after the procedure will give you the best chance for success. The cells are fragile, and you need to be cautious that you don’t overload them or cause too much […]

Does the right side of the brain control? Our brains have two sides, or hemispheres. In most people, language skills are in the left side of the brain. The right side controls attention, memory, reasoning, and problem solving. What is the newest drug for bipolar disorder? 18, 2015 (HealthDay News) — A new antipsychotic drug […]
