Is the only source of heat and light? The presence of hydrogen and helium in very high amount leads the sun to be the only source of heat and light for all planets as hydrogen and helium being a light element do nuclear fusion to form enormous energy with production of heat and light. What […]
Is sweating sympathetic or parasympathetic?
Is sweating sympathetic or parasympathetic? We need sweating to control body temperature; water evaporating from the skin cools the body. Sweating is under the control of the sympathetic nervous system, which orchestrates the body’s reaction to stressful situations and emergencies—sometimes called the “fight or flight” response. How do emotions affect the autonomic nervous system? The […]
What is the 7 Universal Laws?
What is the 7 Universal Laws? To name them, they are the Laws of Mentalism, Correspondence, Vibration, Polarity, Rhythm, Cause and Effect and Gender. Once you understand, apply and align yourself with these seven Universal Laws, you will experience transformation in every area of your life beyond what you have ever dared to imagine. What […]
What is the origin of frictional force?
What is the origin of frictional force? Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Friction originates in nanoscale contacts, as the result of new surface formation. The theory explains the generation of frictional force and frictional heating in dry contact. What energy does friction produce? When friction […]
Why do fizzy tablets dissolve faster in hot water?
Why do fizzy tablets dissolve faster in hot water? In the hot water the tablet should have more vigorously produced bubbles than in the cold water. The higher the temperature, the faster the molecules move—and the more likely it is that the bicarbonate will contact hydrogen in just the right way for the chemical reaction […]
Why does the filament in a light bulb glow more brightly when an electric current is slowly increased?
Why does the filament in a light bulb glow more brightly when an electric current is slowly increased? 4.As the electric current in a lightbulb is slowly increased, the filament glows more and more brightly. Why does this happen? As the current increases, the electrons more frequently bump into more atoms of the resistor (filament) […]
What are the 5 types of seasons?
What are the 5 types of seasons? Meteorological Northern hemisphere Southern hemisphere Start date Winter Summer 1 December Spring Autumn 1 March Summer Winter 1 June Autumn Spring 1 September Which is the hottest day of the year in India? The city had recorded a maximum of 39.6 degrees Celsius on March 29, 1973, the […]
Which is the pathway for information through a neuron?
Which is the pathway for information through a neuron? Explanation: The pathway for information through neuron are dendrite → cell body → axon → axon terminals and this because Dendrite is the input zone of nerve cell where neuron can receive information from another nerve cell. How do neurons send signals? Communication among neurons typically […]
What caused Dust Storm 2020?
What caused Dust Storm 2020? Massive dust clouds are normal, but scientists aren’t sure why it was so bad this year. The dust behind the recent clouds originates at the convergence of two ecosystems: the Sahara and the Sahel. Over half the named storms that we get each year are coming from this nursery over […]
Which material has maximum value of thermal conductivity?
Which material has maximum value of thermal conductivity? Diamond is the leading thermally conductive material and has conductivity values measured 5x’s higher than copper, the most manufactured metal in the United States. Diamond atoms are composed of a simple carbon backbone that is an ideal molecular structure for effective heat transfer. Which material has least […]
