What is internal energy of a system and how it changes? The first law of thermodynamics states that the energy of the universe is constant. The change in the internal energy of a system is the sum of the heat transferred and the work done. The heat flow is equal to the change in the […]
What is the advantage of magnetic separator?
What is the advantage of magnetic separator? A significant advantage of magnetic separation is that no filter cloth or other consumables are necessary, and if the particles are separated with minimal amounts of fluid, the waste that needs to be disposed of is practically limited to the pollution only. As with many separation techniques, the […]
How do you calculate load resistance of a transformer?
How do you calculate load resistance of a transformer? If you mean the AC resistance (called “impedance” in AC circuits), you can calculate it by dividing the rated voltage of the transformer with its rated current, but this is the maximum rated current (meaning the current of the input/primary coil when the output is loaded […]
What are the three key factors for limiting exposure to radiation?
What are the three key factors for limiting exposure to radiation? What are the three key factors for limiting exposure to radiation? The three key factors are time, distance, and shielding. What are the three basic principles of radiation protection? To do this, you can use three basic protective measures in radiation safety: time, distance, […]
What are two methods scientists used to test predictions?
What are two methods scientists used to test predictions? Scientist use experiments and models to test predictions. What are the major problems with observational methods? having to be explicitly involved in recording what they are doing. For example, collecting data without people having to respond to a questionnaire, without having to take part in a […]
How did Jiminy Cricket die?
How did Jiminy Cricket die? In the Original Story, Pinocchio Murdered Jiminy Cricket, Got His Feet Burned Off, And Was Then Hanged and Left for Dead. But, sad to relate, my dear children, he did hit the Cricket, straight on its head. With a last weak “cri-cri-cri” the poor Cricket fell from the wall, dead! […]
How do you make something dissolve faster?
How do you make something dissolve faster? Stirring — With liquid and solid solutes, stirring brings fresh portions of the solvent in contact with the solute. Stirring, therefore, allows the solute to dissolve faster. How does temperature affect dissolution rate? Temperature. Heating up the solvent gives the molecules more kinetic energy. The more rapid motion […]
Can ch3oh form hydrogen bonds?
What happens if you never pay off debt?
What happens if you never pay off debt? If you default on a credit card, loan, or even your monthly internet or utility payments, you run the risk of having your account sent to a collection agency. These third-party companies are hired to pursue a firm’s unpaid debts. You’re still liable for your bill even […]
What type of energy is wave energy MCQs?
What type of energy is wave energy MCQs? This set of Energy Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Wave Energy”. Explanation: Kinetic energy that results from the oscillation of water is called wave energy. Wave energy is derived from wind energy, which derives in turn from solar energy. What is a wave […]
