What is the best fertilizer for plants?
What is the best fertilizer for plants? Fertilizer Selection Most gardeners should use a complete fertilizer with twice as much phosphorus as nitrogen or potassium. An example would be 10-20-10 or 12-24-12. These fertilizers usually are easy to find. Some soils contain enough potassium for good plant growth and don’t need more. What liquids are […]
Why is power transmitted at high voltage?
Why is power transmitted at high voltage? The primary reason that power is transmitted at high voltages is to increase efficiency. The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low also. What are the […]

What are the three effects of friction?
What are the three effects of friction? Effects of Friction It produces heat, that helps in heating parts of any object or to warm ourselves. It also causes loss in power. It produces noise during any kind of operation. It’s because of friction that we’re able to walk, run, play, etc. In what way can […]

How is hydrogen bond formed?
How is hydrogen bond formed? A hydrogen bond is formed when the positive end of one molecule is attracted to the negative end of another. The concept is similar to magnetic attraction where opposite poles attract. Hydrogen has one proton and one electron. This makes hydrogen an electrically positive atom because it has a deficiency […]
