What happens if a white dwarf exceeds 1.4 solar masses? A white dwarf star is in balance between gravity and degeneracy pressure, but if the mass is too large (greater than 1.4 solar masses, called the Chandrasekhar limit), the degeneracy pressure is not adequate to hold up the star, and the star collapses. What happens […]
What happens if nitrogen gains 3 valence electrons?
What happens if nitrogen gains 3 valence electrons? Explanation: But typically a nitrogen atom gains 3 electrons to form the nitride ion, N3− . What is nitrogen called when it gains 3 electrons? The answer is a) nitride ion. The magnitude of the charge of the anion produced depends on the number of electrons gained. […]

Which of the following is the disadvantage of FM over AM?
Which of the following is the disadvantage of FM over AM? FM systems have a much wider bandwidth than AM systems and therefore more prone to selective fading. Frequency modulation requires much wider channel (7 to 15 times) as compared to AM . Which of the following is a drawback of FM system? Burst noise […]
What are the steps involved in hearing?
What are the steps involved in hearing? The Steps of Hearing Outer Ear. Sound waves, which are vibrations, enter through the outer ear and reach the middle ear to vibrate the eardrum. Middle Ear. The eardrum then vibrates the ossicles, which are small bones in the middle ear. Inner Ear. Auditory Nerve. How can you […]
What is unique about experiments?
What is unique about experiments? As we’ve noted before, science is unique because the results of its experiments can be repeated. These changing quantities are called variables, and an experiment usually has three kinds: independent, dependent, and controlled. For more detail, Science Buddies has definitions and examples of the different variables. What two things explode […]
