How does removing a bulb or opening and closing the switch affect a parallel circuit?
How does removing a bulb or opening and closing the switch affect a parallel circuit? An obvious advantage of parallel circuits is that the burnout or removal of one bulb does not affect the other bulbs in parallel circuits. They continue to operate because there is still a separate, independent closed path from the source […]
How do you calculate valve torque?
How do you calculate valve torque? Dynamic torque can be calculated from the formula Td = C (ΔP). Here, ΔP is the effective pressure drop across the valve at a given temperature and C is, once again, a constant. What is Torque valve? A torque-seated valve (e.g., gate valve) will use the torque switches to […]

Continually check your rearview mirror as you gradually slow down. On a multilane road, move into the left lane before reaching the intersection where you plan to turn. How […]
Which sample has maximum density?
Which sample has maximum density? The maximum density of water is at 4°C as there are two opposite effects that are in balance. Why do metals have low density? Since alkali metals have a large atomic size and low atomic weight, they have low density. What are the top 10 densest metals? The 10 Densest […]
Why does water move through a membrane quizlet?
Why does water move through a membrane quizlet? Water moves through a membrane in osmosis because there is a concentration gradient across the membrane of solute and solvent. The solute cannot effectively move to balance the concentration on both sides of the membrane, so water moves to achieve this balance. Why does water move through […]
Which element has longest half-life?
Which element has longest half-life? Bismuth-209 (209Bi) is the isotope of bismuth with the longest known half-life of any radioisotope that undergoes α-decay (alpha decay). What’s so special about element 115? Moscovium is a radioactive, synthetic element about which little is known. It is classified as a metal and is expected to be solid at […]
What is perfect black?
What is perfect black? A body which absorbs all the radiant energy incident upon it and reflects or transmits none is called a perfectly black body. It absorbs all incident energy. What is the meaning of irradiation? Irradiation is the process by which an object is exposed to radiation. The term irradiation usually excludes the […]
