Why do metals have low first ionization energy? Why do metals have a low ionization energy? Because the valence electrons are farther away from the positively charge nucleus, so the force of attraction is low. Why do the alkali metals have low ionization energy? The valence electrons in alkali metals, are very away from the […]
How do you make something positively charged?
How do you make something positively charged? An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged. What happens when the plastic […]

Is India a peninsula? Indian subcontinent and South Asia The Indian subcontinent is a peninsula, the only land feature in the […]
What makes a distant galaxy appear twice when viewed from Earth?
What makes a distant galaxy appear twice when viewed from Earth? The universe’s expansion, when doubled in size, causes all th dots to appear twice as far as they once were, from the perspective of the point of origin. As the universe expands, the galaxies get farther from each other, and the apparent velocity will […]
What is asexual reproduction class 10th?
What is asexual reproduction class 10th? Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parent. Asexual reproduction is observed in both multicellular and unicellular organisms. What […]
What is the correct path of sound through the ear to the brain?
What is the correct path of sound through the ear to the brain? The ossicles amplify the sound. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea). Once the sound waves reach the inner ear, they are converted into electrical impulses. The auditory nerve sends these impulses to […]
How is the resistance of wire affected if its length is doubled?
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 a good resting heart rate by age chart?
What is a good resting heart rate by age chart? According to the American Heart Association, a normal resting heart rate is between 60 (beats per minute) and 100 (beats per minute) for people 15 years and older….What Is A Good Heart Rate for My Age? Age range Heart Rate (beats per minute, or BPM) […]
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 […]
