What is the role of the government in a free market economy? Economists, however, identify six major functions of governments in market economies. Governments provide the legal and social framework, maintain competition, provide public goods and services, redistribute income, correct for externalities, and stabilize the economy. Why government intervention is bad? Government intervention causes more […]
What common properties do Solutions have?
What common properties do Solutions have? Characteristics A solution is a homogeneous mixture of two or more substances. The particles of solute in a solution cannot be seen by the naked eye. A solution does not allow beams of light to scatter. A solution is stable. The solute from a solution cannot be separated by […]
What are hair cells covered by?
What are hair cells covered by? human equilibrium Each has an organ containing hair cells similar to those of the organ of Corti. The utricle and saccule each contain a macula, an organ consisting of a patch of hair cells covered by a gelatinous membrane containing particles of calcium carbonate, called otoliths. Does hair grow […]
What are the charges on the calcium ion?
What are the charges on the calcium ion? Since calcium lost two electrons, it has 20 protons, but only 18 electrons. This makes calcium a positive ion with a charge of 2+. What is the color of calcium nitride? Calcium nitride Names Appearance red-brown crystalline solid Density 2.670 g/cm3 2.63 g/cm3 (17 °C) Melting point […]
Which of the following occupies more volume?
Which of the following occupies more volume? Gases occupy more volume than solids and liquids for the same number of particles because of less inter-molecular force of attraction and more inter-molecular distances. Byjus Asked on June 15, 2016 in Chemistry. Which has maximum volume at STP? Now, it is clear that among the given options, […]
What describes something in nature without attempting to explain it?
What describes something in nature without attempting to explain it? Unlike a theory, a scientific law describes an observed pattern in nature without attempting to explain it. A hypothesis is a possible explanation for a set of observations or answer to a scientific question. What do we call a description of how something works in […]
What 3 places on earth do convection currents occur?
What 3 places on earth do convection currents occur? Convection currents occur within: the atmosphere – wind. the hydrosphere – ocean currents. How convection takes place in the mantle? The mantle is heated from below (the core), and in areas that are hotter it rises upwards (it is buoyant), whereas in areas that are cooler […]
What statement explains the relationship between convection current and plate movements?
What statement explains the relationship between convection current and plate movements? In addition, convection currents occurs because the very hot material at the deepest part of the mantle rises, then cools, sinking again and heating, rising and repeating the cycle over and over again. Thus, all the motion caused by these actions causes plate tectonics […]
What happens when air resistance is increased?
What happens when air resistance is increased? The increase in speed leads to an increase in the amount of air resistance. Eventually, the force of air resistance becomes large enough to balances the force of gravity. At this instant in time, the net force is 0 Newton; the object will stop accelerating. The object is […]
Which rule of Fleming can be used to determine the direction of induced 1 current in the secondary coil if current in the primary coil is changed?
Which rule of Fleming can be used to determine the direction of induced 1 current in the secondary coil if current in the primary coil is changed? Fleming’s Right hand rule – If the forefinger, second (central) finger and thumb of the right hand are stretched at right angles to each other, with the forefinger […]
