How can we increase the speed of motor give two ways? The speed of rotation of an electric motor can be increased by: (i) increasing the strength of the current, (ii) increasing the number of turns in the coil. What is DC motor speed? Speed of a DC Motor A = number of parallel paths. […]
How does recycling water help the environment?
How does recycling water help the environment? What are the Environmental Benefits of Water Recycling? Water Recycling Can Decrease Diversion of Freshwater from Sensitive Ecosystems. Water Recycling Decreases Discharge to Sensitive Water Bodies. Recycled Water May Be Used to Create or Enhance Wetlands and Riparian (Stream) Habitats. How can we reduce reuse and recycle water […]
Why is a 1982 D penny rare?
Why is a 1982 D penny rare? Newly found 1982-D Small date copper cent. The Mint switched over from striking copper-alloy to copper-plated zinc planchets sometime in mid-1982 as a cost saving measure – the copper-alloy planchets were too expensive to strike and the Mint was losing money. But it didn’t end there. What are […]
What acetone Cannot dissolve?
What acetone Cannot dissolve? Many kinds of plastic do not dissolve in acetone. Polypropylene and nylon are unaffected, PTFE unsurprisingly handles it just fine as well. Two kinds of plastic that do dissolve in acetone are PVC and polystyrene. Why is nail polish soluble in acetone but not in water? Nail varnish does not dissolve […]
What are the two types of electrostatic fields?
What are the two types of electrostatic fields? The electric field is mainly classified into two types. They are the uniform electric field and the nonuniform electric field. How do you know if a field is electrostatic? A vector field is a possible electric field in the electrostatic regime if and only if its curl […]
What is nerve impulse in simple words?
What is nerve impulse in simple words? A nerve impulse is the way nerve cells (neurons) communicate with one another. Nerve impulses are mostly electrical signals along the dendrites to produce a nerve impulse or action potential. The action potential is the result of ions moving in and out of the cell. What are the […]

What is the working principle of capacitor?
What is the working principle of capacitor? A capacitor works on the principle that the capacitance of a conductor increases appreciably when an earthed conductor is brought near it. Hence, a capacitor has two plates separated by a distance having equal and opposite charges. What is the main function of capacitor? A capacitor is an […]
Why are periodic forest fires beneficial to the forest?
Why are periodic forest fires beneficial to the forest? When done in small doses, controlled burns can be beneficial to forest growth. Naturally, periodic forest fires help to clear away old brush and allow for new growth. They recycle nutrients back into the soil, disperse seeds of fire-adapted plants and burn ground cover to give […]
