Why is nuclear energy bad? Nuclear energy produces radioactive waste A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years. Is nuclear energy safe? […]
Which two factors are needed to calculate the velocity of an object?
Which two factors are needed to calculate the velocity of an object? The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is a physical vector quantity; both magnitude and direction are needed to define it. Speed, the […]
Is it possible for a heat engine to operate without rejecting any waste heat to a low temperature reservoir explain?
Is it possible for a heat engine to operate without rejecting any waste heat to a low temperature reservoir explain? It is not possible for a engine to operate without rejecting any waste heat to a low temperature reservior. It violates the second law of thermodynamics, the operation of a heat engine a low temperature […]

Does the human body use neptunium?
Does the human body use neptunium? Some is also retained in the liver. Several studies report “relatively high concentrations” of neptunium in adrenal glands of laboratory animals. No health effects specific to exposure from neptunium “have been observed” in human beings. Where is neptunium commonly found? Source: Miniscule concentrations of neptunium-237 and neptunium-239 are found […]
Does higher pressure mean more flow?
Does higher pressure mean more flow? Flow rate is the effect. Higher pressure causes increased flow rate. If the flow rate increases, it is caused by increased pressure. What is the relation between speed and flow rate? Flow rate and velocity are related by \(Q=A\overline{v}\\\) where A is the cross-sectional area of the flow and\(\overline{v}\\\) […]

What is the substance of matter? substance: A form of matter that has constant chemical composition and characteristic properties. It is composed of one type of atom […]
What are the types of radio stations?
What are the types of radio stations? Different types of radio Conventional FM: As previously mentioned, conventional FM is a popular technology in analog radio. MPT1327: Perhaps the most widely used analog trunking technology today is called MPT 1327. Tetra: As the world becomes more digital, a number of digital radio technologies have emerged. Who […]
What is one effect of the uneven heating of Earth caused by the sun?
What is one effect of the uneven heating of Earth caused by the sun? Usually when we talk about uneven heating of the Earth’s surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and […]
