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. […]
Why hydrogen ion does not exist?
Why hydrogen ion does not exist? Because the bare nucleus can readily combine with other particles (electrons, atoms, and molecules), the isolated hydrogen ion can exist only in a nearly particle-free space (high vacuum) and in the gaseous state. Why are H+ ions? Loss of an electron from H atom results in H+ . ion […]

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 […]
How does electricity flow in a circuit draw an open circuit?
How does electricity flow in a circuit draw an open circuit? The electric circuit in which there is a gap in the connections between the terminals of the cell, wires and the bulb, etc is called an open circuit (or incomplete circuit). Electricity does not flow through an open circuit because there is a gap […]
What happens when stomata are open?
What happens when stomata are open? When stomata are open, water vapor and other gases, such as oxygen, are released into the atmosphere through them. A number of factors can affect the exchange of gases between a leaf and the atmosphere. What allows stomata to open and close? Specialized cells known as guard cells surround […]
