Which of the following is correct about action reaction pair? Newton’s Third law states that the equal and opposite action-reaction pair acts on different bodies. Hence, the correct option is B. Note: Whenever two bodies interact, they exert equal and opposite forces on each other. Are N and Mg action reaction pair? Gravity, weight and […]

How long did it take to load a gun in 1791?
How long did it take to load a gun in 1791? about thirty seconds Are Matchlock guns accurate? An antique 17th century matchlock was tested in Austria (IIRC) against a man sized silhouette. The gun was aimed and fixed directly onto the center of the targets chest. At 100 meters it hit 50% percent of […]
How do you find the pH of 0.01 m NaOH?
Can an object be completely transparent?
Can an object be completely transparent? Materials like air, water, and clear glass are called transparent. When light encounters transparent materials, almost all of it passes directly through them. Glass, for example, is transparent to all visible light. Translucent objects allow some light to travel through them. What are the conditions for an object to […]
What are the 4 fundamental forces from weakest to strongest?
What are the 4 fundamental forces from weakest to strongest? Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity. What is the highest form of love? Philia What are […]
How are gas turbines cooled?
How are gas turbines cooled? Fogging. Inlet air fogging consists of spraying finely atomized water (fog) into the inlet airflow of a gas turbine engine. The water droplets evaporate quickly, which cools the air and increases the power output of the turbine. What is reheating and regeneration of gas turbine? Reheating is applied in a […]
What is the difference between lithosphere hydrosphere and atmosphere?
What is the difference between lithosphere hydrosphere and atmosphere? The atmosphere, therefore, consists of gases that envelop the Earth. The hydrosphere defines the water that covers 71% of the Earth’s surface. The lithosphere refers to the rocks of the Earth’s surface and upper mantle, or the depth of the plates. As you go higher in […]
Which way does heat flow?
Which way does heat flow? And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation. Sometimes more than one may occur at the same time. What is Celsius […]
What percent humidity should I set my dehumidifier at?
What percent humidity should I set my dehumidifier at? The optimal relative humidity level is between 30 and 50 percent, according to Energy Star (and 30 to 40 percent in colder areas during heating season). If the humidity is higher than that, it can breed dust mites, mildew, and mold, and trigger allergies. Can mold […]
