What month do we get more daylight? March Why is there less sun in the winter? During winter, the Northern Hemisphere leans away from the sun, there are fewer daylight hours, and the sun hits us at an angle; this makes it appear lower in the sky. There is less heating because the angled sun’s […]
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 […]
Why is nuclear energy bad?
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? […]
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 […]
What is the difference between the collision-coalescence process and the Bergeron process?
What is the difference between the collision-coalescence process and the Bergeron process? Unlike the Bergeron Process, where precipitation forms under supercooled conditions, the Collision and Coalescence Process typically occurs within relatively warm clouds with tops warmer than -15C. 4) The cloud must be thick enough so that the cloud droplets have enough time to gather […]
Does altitude affect cooking time?
Does altitude affect cooking time? At high altitudes: Air pressure is lower, so foods take longer to cook. Temperatures and/or cook times may need to be increased. Water boils at a lower temperature, so foods prepared with water (such as pastas and soups) may take longer to cook. How do you bake at elevation? High-Altitude […]
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 […]
