What is easier rolling or sliding? When an object rolls over the surface of another object ,the resistance to its motion is called rolling friction. It is always easier to roll than to slide an object over another object.So rolling friction is much less than the sliding friction. Why is sliding faster than rolling? 25ex2 […]
How wages are determined?
How wages are determined? Just as in any market, the price of labor, the wage rate, is determined by the intersection of supply and demand. When the supply of labor increases the equilibrium price falls, and when the demand for labor increases the equilibrium price rises. What are the factors affecting wages and salary? The […]

How do kinetic energy heat and temperature affect each other?
How do kinetic energy heat and temperature affect each other? The thermal energy, or heat, of an object is obtained by adding up the kinetic energy of all the molecules within it. Temperature is the average kinetic energy of the molecules. Absolute zero is the temperature where molecular motion stops and is the lowest possible […]
How do I figure out how much soil I need for a raised bed?
How do I figure out how much soil I need for a raised bed? How to find soil volume for square or rectangular beds Measure the length, width and height of your bed. (Unless the boards are very thick, don’t worry about inside/outside measurements.) Multiply all the measurements together: 6 x 3 x 1.4 = […]
How has plate tectonics affect evolution?
How has plate tectonics affect evolution? Plate tectonic processes such as the redistribution of continents, growth of mountain ranges, formation of land bridges, and opening and closing of oceans provide a continuous but moderate environmental pressure that stimulates populations to adapt and evolve. Why are plate tectonics important to the ocean? Earth’s oceans might not […]

If you have carpeted floors, or work in a carpeted office, wearing rubber soled shoes greatly increases your chance of experiencing static shock. Opt for leather-soled shoes instead. Does wearing rubber slippers prevent electric shock? In answer to the second question, […]
What is the principle of electric iron?
What is the principle of electric iron? An electric iron is based on the principle of heating effect of current that heat is produced in the nichrome wire used in the iron due to the current flowing through it. Which coating is best for iron? Which soleplate is best for ironing? Stainless steel soleplates have […]
