Answer the following question given this paragraph: Two important devices depend on electromagnetic induction: electric generators and electric transformers. Both devices play critical roles in producing and regulating the electric current we depend on in our daily lives. Electric generators use electromagnetic induction to change kinetic energy to electrical energy. They produce electricity in power plants. Electric transformers use electromagnetic induction to change the voltage of electric current. Some transformers increase voltage and other decrease voltage. Q: What type of generators use electromagnetic induction to change kinetic energy to electrical energy? Choices: - conductors - radiators - thermal generators - electric generators A:
electric generators

Answer the following question given this paragraph: There are several different equations that better approximate gas behavior than does the ideal gas law. The first, and simplest, of these was developed by the Dutch scientist Johannes van der Waals in 1879. The van der Waals equation improves upon the ideal gas law by adding two terms: one to account for the volume of the gas molecules and another for the attractive forces between them. Q: Which equation improves upon the ideal gas law by adding two terms: one to account for the volume of the gas molecules and another for the attractive forces between them? Choices: - Heidiger's principle - Pascal's equation - Newton's third law - van der waals A:
(Answer)
van der waals
Ques: Answer the following question given this paragraph: It may be logical to assume that the electrolysis of aqueous sodium chloride, called brine , would yield the same result through the same reactions as the process in molten NaCl. However, the reduction reaction that occurs at the cathode does not produce sodium metal because the water is reduced instead. This is because the reduction potential for water is only -0.83 V compared to -2.71 V for the reduction of sodium ions. This makes the reduction of water preferable because its reduction potential is less negative. Chlorine gas is still produced at the anode, just as in the electrolysis of molten NaCl. Q: Where is chlorine gas produced? Choices: - in the nucleus - carbon cycle - epidermis - at the anode A:
Ans: at the anode

Answer the following question given this paragraph: Refusing one meal won't stunt your growth. But lack of proper food over a period of time can lead to malnutrition. That means, the body is not getting enough nutrients to grow and stay healthy. Kids who are malnourished may not grow as tall as they would otherwise. Q: Lack of proper food over a period of time can lead to what condition, where the body is not getting enough nutrients to grow and stay healthy? Choices: - anemia - mortality - bulimia - malnutrition A:
(A).
malnutrition
Ques:Answer the following question given this paragraph: Diffusion will continue until the concentration gradient has been eliminated. Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient. " The end result of diffusion is an equal concentration, or equilibrium , of molecules on both sides of the membrane. At equilibrium, movement of molecules does not stop. At equilibrium, there is equal movement of materials in both directions. Q: The end result of diffusion is an equal concentration, or equilibrium , of molecules on both sides of what? Choices: - the cell - the organism - the organelle - the membrane A:

Ans:the membrane
Ques:Answer the following question given this paragraph: Q: White light is a mixture of all wavelengths of what? Choices: - gamma radiation - infrared radiation - x-rays - visible light A:

Ans:
visible light
