What is internal energy of a system in physics? In chemistry and physics, internal energy (U) is defined as the total energy of a closed system. Internal energy is the sum of potential energy of the system and the system’s kinetic energy. Is internal energy same as heat? ‘Thermal’ energy and ‘Heat’ energy mean the […]
What are the 5 properties of metals?
What are the 5 properties of metals? Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Is oxygen a metal or nonmetal? Oxygen, carbon, sulfur and chlorine are examples of non-metal elements. Non-metals have properties in common. Is Potassium a metal or nonmetal? Potassium is a soft, silvery-white metal, member of the alkali […]
What is the formula for wave period?
What is an example of fallacious reasoning?
What is an example of fallacious reasoning? Example: “People have been trying for centuries to prove that God exists. But no one has yet been able to prove it. Therefore, God does not exist.” Here’s an opposing argument that commits the same fallacy: “People have been trying for years to prove that God does not […]
What is a lysosomes function?
What is a lysosomes function? A lysosome is a membrane-bound cell organelle that contains digestive enzymes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. What are the two main functions of lysosomes? A lysosome has three main functions: the breakdown/digestion of macromolecules (carbohydrates, lipids, proteins, […]
What is the most active galaxy?
What is the most active galaxy? ACTIVE GALAXIES Quasars, blazars, Seyfert galaxies, and radio galaxies are all active galaxies. Active galaxies contain an accretion disk around a central black hole, with two perpendicular jets. An active galaxy’s appearance depends on the orientation of the accretion disk. Can a galaxy explode? The biggest cosmic explosion on […]

What is the heaviest planet in the universe? Jupiter What is the heaviest planet? Fifth in line from the Sun, Jupiter is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. What is the least densest planet? Saturn What is the smallest planet […]
Which algorithm is used for public key encryption?
Which algorithm is used for public key encryption? RSA Is asymmetric encryption more secure than symmetric? Asymmetric encryption is the more secure one, while symmetric encryption is faster. They’re both very effective in different ways and, depending on the task at hand, either or both may be deployed alone or together. Only one key (symmetric […]
How tight should a dirndl be?
What force is used to hit a ball with a bat?
What force is used to hit a ball with a bat? So, during the bat-ball collision, an average force of roughly two tons acts during the 0.7 millisecond contact time, with a peak force of about four tons. That’s a lot of force! We can determine the average acceleration experienced by the ball from Newton’s […]
