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 […]
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 […]
How do you magnetize metal permanently?
How do you magnetize metal permanently? Take two magnets put one North pole and one South pole on the middle of the iron. Draw them towards its ends, repeating the process several times. Take a steel bar, hold it vertically, and strike the end several times with a hammer, and it will become a permanent […]
What are the three main types of body membranes?
What are the three main types of body membranes? There are three types of epithelial membranes: mucous, which contain glands; serous, which secrete fluid; and cutaneous which makes up the skin. What are the three functions of body membranes? Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) […]
What is chain reaction with example?
What is chain reaction with example? In chain reaction. Nuclear chain reactions are series of nuclear fissions (splitting of atomic nuclei), each initiated by a neutron produced in a preceding fission. For example, 21/2 neutrons on the average are released by the fission of each uranium-235 nucleus that absorbs a low-energy neutron. What is another […]
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 […]
Where should you connect a voltmeter?
Where should you connect a voltmeter? A voltmeter is placed in parallel with the voltage source to receive full voltage and must have a large resistance to limit its effect on the circuit. An ammeter is placed in series to get the full current flowing through a branch and must have a small resistance to […]
What is the fastest way to solve math questions?

Multiplying 5 times any number. Division tricks. Multiplying by 9. 10 and 11 times tricks. Percentage. Quickly square a two-digit number that ends in […]
Where is the magnetic field strongest?
Where is the magnetic field strongest? center Why does electricity produce magnetic fields? Inside a magnet, the atoms at one end contain electrons that all spin in one direction – meanwhile the atoms at the other end contain electrons that all spin in the opposite direction. Rather than spinning in a balanced way, the electrons […]
