What are perfect substitutes? A perfect substitute can be used in exactly the same way as the good or service it replaces. This is where the utility of the product or service is pretty much identical. For example, a one-dollar bill is a perfect substitute for another dollar bill. What is the MRS of perfect […]
What are the factors that affect the kinetic energy of the vehicle?
What are the factors that affect the kinetic energy of the vehicle? 1. Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed. Have students complete this demonstration to learn how mass influences an object’s kinetic energy. Does height affect energy? Since the gravitational potential […]
What does temperature of inversion depend on?
What does temperature of inversion depend on? This temperature depends on the temperature of the cold junction and the nature of the material. What is thermo emf? A thermo EMF(E) arises when two metal junctions are maintained at different temperatures. Thermo emf is developed by keeping one juction at 0∘C and varies with temperature and […]
Which of the following is equal to 2 3?
Which of the following is equal to 2 3? Answer:4/6, 6/9, 8/12, 5/10 are equivalent to 2/3. All those fractions obtained by multiplying both the numerator and denominator of 2/3 by the same number are equivalent to 2/3. Which of the following is not equal to the three? Answer. d 34/68 is not equal to […]
What is formula of intensity of light?
What is formula of intensity of light? The intensity is defined as power per unit area, and power is defined as energy per unit time. Thus: I=PA=EΔt1A. How do you measure water intensity? Water Use Intensity (All Water Source) = all water sources divided by the building sq. ft. (not including parking or irrigated area). […]

Which two gases are the most effective at absorbing longwave radiation?
Which two gases are the most effective at absorbing longwave radiation? Greenhouse gases in the atmosphere (such as water vapor and carbon dioxide) absorb most of the Earth’s emitted longwave infrared radiation, which heats the lower atmosphere. Why Earth’s surface does not get hotter and hotter? The Earth does not continue to get hotter and […]
What are the 7 Millennium Problems?
What are the 7 Millennium Problems? Clay “to increase and disseminate mathematical knowledge.” The seven problems, which were announced in 2000, are the Riemann hypothesis, P versus NP problem, Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier-Stokes equation, Yang-Mills theory, and Poincaré conjecture. Who has solved the Navier Stokes equation? Russian mathematician Grigori Perelman was awarded […]
How is power calculated?
Is the focal length of a spherical mirror?
Is the focal length of a spherical mirror? The distance from the pole to the focal point is called the focal length (f). The focal length of a spherical mirror is then approximately half its radius of curvature. What is the focal length for plane mirror? infinity Is Focal Length always positive? The distance from […]
