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 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) […]
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 […]
How much does the tension in the string increase if we double the speed?
How much does the tension in the string increase if we double the speed? When the wave relationship is applied to a stretched string, it is seen that resonant standing wave modes are produced. So, if we double the tension the speed will increase 1.41 times or root (2) times. What happens if weight is […]

Household Vinegars. Citric Acid. What are some bases at home? 1 Answer Sodium Bicarbonate – Baking Soda. Soap (A mild base) Oven Cleaner. Drain Cleaner. Toothpaste. […]
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 […]
What animals live in a cave?
What animals live in a cave? Extant trogloxene animals include rats, raccoons, opiliones, and bears. During the third interglacial epoch and the fourth glacial advance, a large number of now extinct species inhabited the caves of the world. Cave bears, cave leopards, cave lions, and cave hyenas are examples of these extinct animals. Can you […]
How many half-lives until a drug is out of your system?
How many half-lives until a drug is out of your system? Even further, 94 to 97% of a drug will have been eliminated after 4 to 5 half-lives. Thus, it follows that after 4 to 5 half-lives, the plasma concentrations of a given drug will be below a clinically relevant concentration and thus will be […]
