Does wavelength change with distance? As light travels away from a galaxy, the Universe is continually expanding, meaning that the distance the light needs to travel is continually increasing as well. As space stretches out underneath a beam of light, its wavelength increases, and its energy decreases. Does frequency increase with distance? The frequency of […]

How do you calculate the number of turns in a transformer? Windings and Wire You now need to determine the number of turns that will be required for each secondary winding. The first step is to use formula 3 (N(s) = V(s) / V(p) x N(p)) to determine the turns for a perfect transformer. This […]

What is the easiest tree to grow from seed? Acorns turn into oaks, and finding space for one of those in the city can be hard, but crab apples, hazelnuts, rowans, white beans and service trees (Sorbus species) are all easy from seed and suitable for small gardens or allotments (and they’ll give you something […]

Is O2 stronger than H2? Answer: Bond enthalpy of O2 is greater than that of H2 as it contains double bond between oxygen atoms While hydrogen atoms in H2 are bonded by single bond. mark me as brainliest. Which is stronger h2 or cl2? The same reasoning applies to this question. Two chlorine atoms are […]

What are the 4 tasks of the auditory system? What are the four tasks of the auditory system? – Pick up stimulus energy from the world around us. – Change that energy into a pattern of neural impulses. – Carry those impulses to the proper locations in the brain. What are the 3 aspects of […]

What is the minimum sample size? 100 Why is 30 the magic number for sample size? It’s not that “30 in a sample group should be enough” for a study. It’s that you need at least 30 before you can reasonably expect an analysis based upon the normal distribution (i.e. z test) to be valid. […]

Are lower taxes better for the economy? Tax Cuts and the Economy Further, reduced tax rates could boost saving and investment, which would increase the productive capacity of the economy. In other words, economic growth is largely unaffected by how much tax the wealthy pay. Growth is more likely to spur if lower income earners […]

Is a 20 volt drill more powerful than a 12 volt drill? 1. Power. The main difference between 12v, 18v, and 20v tools is their power; the higher the voltage of the tool means the more influential the tool is, so here the voltage is 12, 18, and 20 volts, indicating the 12v tool has […]

Why is it important to submit assignments on time? Homework provides students with necessary practice in writing, thinking, reading, and problem-solving. Doing homework in time is very important since it will show your professor that you are a serious student who is interested in the subject. If you perform all your tasks on time, this […]

What is the most important thing in science? In order to do scientific activity, to know the truth of nature through study or research, scientist must do that based on empiricism, experimentation and methodological. Those three foundations in science are integrated into a so-called scientific method. This is the most important thing in science. What […]
