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 = […]

When a parallel plate capacitor is being charged by a DC battery Why does a galvanometer? Answer Expert Verified During charging and discharging of the capacitor, there is a flow of charge from the battery towards the plates of the capacitor, which produces a conduction current in the circuit. Hence, the galvanometer present in the […]

What function does a nucleus have? The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Is the nucleolus inside the nucleus? The nucleolus is a region found within the cell nucleus that is concerned with producing and assembling the cell’s […]

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. […]

Are 2s and 2p degenerate? The 2s and 2p orbitals have the same energy for hydrogen. They are said to be degenerate energy levels, all the same. When the electron is held in the 1s orbital, it is said to be in its ground state, its lowest energy state. When the electron is a higher […]

What are the origin of the universe? The best-supported theory of our universe’s origin centers on an event known as the big bang. This theory was born of the observation that other galaxies are moving away from our own at great speed in all directions, as if they had all been propelled by an ancient […]
