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 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 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 […]

Can you manipulate more than one variable? The short answer to whether scientists can use more than one manipulated variable in their experiments is “yes.” But just as important as the answer to this question is understanding why scientists would want to include two manipulated variables. How many control variables can you have? Similar to […]

What do you do if you hit black ice? Deal with a black ice encounter. If you do hit black ice, your first reaction must be to remain calm and avoid overreacting. The general rule is to do as little as possible and allow the car to pass over the ice. Do not hit the […]

Why is chemical change not easily reversible? chemical change never reversed because it produce new substance after reaction which is not reversible . if it is reversed , it can’t called chemical reaction , it called physical reaction. Is a chemical change reversible? In principle, all chemical reactions are reversible reactions . This means that […]

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 […]
