What are three factors that affect the flow of current in a circuit? Answer. Answer: Voltage, resistance, and whether the circuit is wired in series or parallel. The current in a circuit depends on the applied voltage and the resistance of the circuit. Why do we say current flows from positive to negative? The direction […]
How is food transported in plants explain Class 10?
How is food transported in plants explain Class 10? The phloem tissue in plants transports food materials from the leaves to different parts of the plant. As a result, the osmotic pressure in the tissue increases forcing the water to move through it. This pressure moves the materials in phloem to the tissues which have […]
What causes resistance in a wire?
What causes resistance in a wire? The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance. The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. […]

What stage of sleep is hardest to awaken?
What stage of sleep is hardest to awaken? It is most difficult to awaken people from slow-wave sleep; hence it is considered to be the deepest stage of sleep. Following a period of slow-wave sleep, however, EEG recordings show that the stages of sleep reverse to reach a quite different state called rapid eye movement, […]

What causes neon to glow?
What causes neon to glow? Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases. A high potential of several thousand volts applied to the electrodes ionizes the gas in the tube, causing it to emit colored light. The color of the light depends on the gas […]
