Which best describes a difference between transformations in power plants and dams? The difference between the energy transformations in power plants and dams would be that dams are the ones who uses mechanical energy to produce electricity. It uses turbines to convert mechanical to electrical. Which best describes a difference between energy transformations in power […]

What do you mean by central orbit? A central orbit is an orbit in which the attractive force between a central mass and test mass is a central force, i.e., is directed towards the central mass. A general central force law is therefore given by. (1) for any function f(r), where is the force per […]

What is considered a strong wind for cycling? 35-40 mph or more and I would begin to consider staying in. Around here if we didn’t ride in 20-30+mph winds …well…then we wouldn’t ride much. 35-40 mph or more and I would begin to consider staying in. How much wind is considered windy? According to the […]

What is Chyme in the digestive system? Chyme, a thick semifluid mass of partially digested food and digestive secretions that is formed in the stomach and intestine during digestion. In the stomach, digestive juices are formed by the gastric glands; these secretions include the enzyme pepsin, which breaks down proteins, and hydrochloric acid. When is […]

Which of the following is a case of steady state heat transfer? Solution(By Examveda Team) Heating of building in winter-Conduction is heat traveling through a solid material. On hot days, heat is conducted into your home through the roof, walls, and windows. Which of the following is a case of heat transfer by radiation? Solution(By […]

How many times more light can the telescope gather than the human eye? So the telescope can gather light for 900 times longer than the eye, to make a single image! The long exposure time of the telescope’s camera enables it to gather much more light than the eye. This enables telescopes to detect much […]

What is the principle of mass spectrograph? “The basic principle of mass spectrometry (MS) is to generate ions from either inorganic or organic compounds by any suitable method, to separate these ions by their mass-to-charge ratio (m/z) and to detect them qualitatively and quantitatively by their respective m/z and abundance. What is the use of […]

For example, if the incident has been proven to be caused by the building owner’s negligence, they are liable. You should have a contract […]

How does the kinetic theory explain Charles Law? Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles’ and Boyle’s Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only. What […]
