How is the resistance of wire affected if its length is doubled? (a) Resistance of a wire is directly proportional to the length of a wire; so if the length is doubled, resistance is also doubled. (b) Resistance of a wire is inversely proportional to the area of cross-section the wire. Thus, if radius is […]
What is the effect of change of temperature on the solubility of a salt Class 9?
What is the effect of change of temperature on the solubility of a salt Class 9? Solubility at 293 K (d) The solubility of most of the salts increases in with increase in temperature. But for same salts like sodium chloride there is no effect of temperature on the solubility. For same salts like Cerium […]
What is the main function of the olfactory bulb?
What is the main function of the olfactory bulb? Olfactory bulb, structure located in the forebrain of vertebrates that receives neural input about odours detected by cells in the nasal cavity. The axons of olfactory receptor (smell receptor) cells extend directly into the highly organized olfactory bulb, where information about odours is processed. Where is […]
Is a path of electricity?
Is a path of electricity? Electric Circuit A continuous and closed path of an electric current is called a circuit. The point where the electrons enter an electrical circuit is called the “source” of electrons. The point where the electrons leave an electrical circuit is called the “return” or “earth ground”. What is the chemical […]
How many times a day do prisoners eat?
What happens when loop of Henle is removed?
What happens when loop of Henle is removed? The principal function of the loop of Henle appears to be the recovery of water and sodium chloride from the urine. Thus, if Henle’s loop were absent from mammalian nephron, urine will be more dilute. What happens if tubule of nephron is removed? About 65% of the […]
What is the formula of weak nuclear force?
What is the formula of weak nuclear force? Weak interaction – Force between two weakly interacting objects which are r meters apart is given by: F(weak) = 0 N Strong interaction – Force between two strongly interacting objects which are r meters apart is given by: F(strong) = 10000000000 N or equally well 0 N […]
What are the two types of reproduction What is the difference between the two types?
What are the two types of reproduction What is the difference between the two types? Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique. What are disadvantages of asexual reproduction? The disadvantage of […]
Will coconut oil dissolve sugar?
Will coconut oil dissolve sugar? Place 1/2 cup sugar in a small bowl. Add the slightly softened LouAna Organic Coconut Oil. Use your fingers to mix the sugar and coconut oil together, but not so much that the sugar dissolves. What does not dissolve in water? Many substances will not dissolve in water, including oil, […]
What is a conduction electron?
What is a conduction electron? [kən′dək·shən i′lek‚trän] (solid-state physics) An electron in the conduction band of a solid, where it is free to move under the influence of an electric field. Also known as outer-shell electron; valence electron. Why are valence electrons in metals called conduction electrons? They are called conduction electrons, since they are […]
