What are the 8 steps in scientific method? That procedure is commonly called the scientific method and consists of the following eight steps: observation, asking a question, gathering information, forming a hypothesis, testing the hypothesis, making conclusions, reporting, and evaluating. How do you design an experiment to test a hypothesis? Experimental design means creating a […]
What is the difference between boron and silicon?
What is the difference between boron and silicon? Boron is exclusively found in the mineral fraction of bone. Silicon is distributed equally in the mineral and collagen fractions. Data suggest boron and silicon have different biological effects on bone. Silicon loading into bone mineral may be influenced by nutritional factors. What is boron used for? […]
How do printers use static electricity?
How do printers use static electricity? Photocopiers. This flow chart outlines how a photocopier works. Ink jet printers use static electricity to guide a tiny jet of ink to the correct place on the page. Laser printers work in a similar way. How does aluminum foil make static electricity? Electricity experiment for kids instructions: Cut […]
What are the 5 phases of the moon?
Are heat and temperature inversely proportional?
Are heat and temperature inversely proportional? (a) The amount of heat transferred is directly proportional to the temperature change. To double the temperature change of a mass m, you need to add twice the heat. (c) The amount of heat transferred depends on the substance and its phase. How will the difference in temperature of […]
Do humans need enrichment?
Do humans need enrichment? Ultimately for humans, enrichment needs to make us feel valued and good about the contribution we are making. As with animals, there is not one form of enrichment that works for all. What is the primary source of enrichment for rats? For rats and mice, I place high-fiber rabbit food in […]
Is 30 minutes of cardio a day enough to lose weight?
Is 30 minutes of cardio a day enough to lose weight? A new study shows 30 minutes of exercise a day works just as well as an hour in helping overweight adults lose weight. Can you burn fat without cardio? That’s right – you can cut without doing traditional cardio. There’s no denying that sprints […]
What would be the path of reflected light if an incident ray passes through focus?
What would be the path of reflected light if an incident ray passes through focus? An incident ray passing through the focus will be reflected parallel to the principal axis. Why the light ray retraces its path when it passes through Centre of curvature? Answer: The reason for light falling on the centre of curvature […]
What is the relationship between wavelength and speed?
What is the relationship between wavelength and speed? Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed. What is the longest […]
How long is a freight train allowed to be?
How long is a freight train allowed to be? According to data that two Class I railroads provided to us, their average train length increased over the 10-year period of 2008 through 2017 by about 1,500 feet for one railroad (from about 6,000 to 7,500 feet, or up to about 1.4 miles) and about 1,200 […]
