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 […]
How do you increase surface area?
How do you increase surface area? The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder. How can you increase the surface area of water? Surface tension is the energy […]
What is the best form of power?
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\(\overline{v}\\\) […]
Why does temperature increase with mass?
Why does temperature increase with mass? If density increases ,volume decreases and if density decreases , volume increases. So density*volume=mass remains same as before. Gravitational pressure increases the more mass there is, and that pressure creates energy that increases temperature. Why does it take longer to heat up a larger volume of water? Simple: you’re […]
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 […]
What are the 3 main map projections?
What are the 3 main map projections? This group of map projections can be classified into three types: Gnomonic projection, Stereographic projection and Orthographic projection. What are the 5 map projections? Top 10 World Map Projections Mercator. This projection was developed by Gerardus Mercator back in 1569 for navigational purposes. Robinson. This map is known […]
What phase comes after the new moon?
What phase comes after the new moon? waxing crescent What is the correct order of the moon phase? The 8 moon phases in order are New moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full moon, Waning Gibbous, Last Quarter, and finally Waning Crescent. The moon has phases the wanes, waxes, and even sometimes we can’t […]
Is 50 hp enough for a motorcycle?
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 […]
