Is there a relationship between speed and acceleration? Speed is the distance covered in a unit of time while acceleration is the rate of change of speed. The unit of speed in the metric system is meters per second (m/s) while that of acceleration is meters per second squared (m/s2). Speed is a scalar quantity […]

During daylight hours, which range from 11 hours in winter to 13 in summer, it has a 90% possibility of sunshine. What angle does the sun […]
What are the 3 factors that impact natural selection?
What are the 3 factors that impact natural selection? Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited […]
What are the three types of pain receptors?
What are the three types of pain receptors? Within the central nervous system, there are three types of opioid receptors which regulate the neurotransmission of pain signals. These receptors are called mu, delta, and kappa opioid receptors. What are the two types of pain fibers? Each of the spinal nerves emerging from the spinal cord […]
What is the function of Nucleous?
What is the function of Nucleous? The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. What function does the nucleolus perform? The nucleolus is a dynamic membrane-less structure whose primary function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis. What […]
What are the negative effects of infrared?
What are the negative effects of infrared? IR, particularly IR-A or near IR [700nm-1400nm], raises the internal temperature of the eye, essentially “baking” it. Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively. Can infrared radiation kill you? Infra-red light affects […]
What is the minimum energy of harmonic oscillator?
What is the minimum energy of harmonic oscillator? Classically, the lowest energy available to an oscillator is zero, which means the momentum also is zero, and the oscillator is not moving. Compare the quantum mechanical harmonic oscillator to the classical harmonic oscillator at v=1 and v=50. On what factor does the angular frequency of simple […]
What is another word for isotope?
What is another word for isotope? What is another word for isotope? element form variant version What is the correct statement about isotopes? Isotopes of only heavier elements are radioactive in nature as they have large difference in the number of protons and neutrons. Thus, we can conclude that the statement isotopes of the same […]
