Why do divers exhale when surfacing? As the diver ascends, the air in the lungs expands as surrounding water pressure decreases. Exhaling allows excess volume to escape from the lungs, and by exhaling at a suitable rate the diver can continue exhaling throughout the ascent and still have air in his or her lungs at […]

What are the 4 properties of atom? Chemical properties Atomic number. The atomic number indicates the number of protons within the core of an atom. Atomic mass. The name indicates the mass of an atom, expressed in atomic mass units (amu). Electronegativity according to Pauling. Density. Melting point. Boiling point. Vanderwaals radius. Ionic radius. Do […]

What are the 3 equations for power? Ohm’s law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = […]

What is KD in PUBG? In PUBG Mobile’s new method of K/D calculation, the number of games a player has played is taken into account. The kill death ratio is calculated by dividing the total number of kills made by a player by the total number of matches played by the said player. New K/D […]

Is triode a diode? Triode tubes A triode is much like the diode vacuum tube, except that it has an additional part: a metal wire grid, between the heated filament and plate. The small radio signal coming from the antenna is fed into the grid, and it greatly alters the voltage flowing through the triode. […]

What happens when you put a magnet near a compass? The needle of a compass is itself a magnet, and thus the north pole of the magnet always points north, except when it is near a strong magnet. When you take the compass away from the bar magnet, it again points north. So, we can […]

Does reactivity increase left to right? Chemical reactivity of the elements – definition Period – reactivity decreases as you go from left to right across a period. The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity. […]
