What is the purpose of units?
What is the purpose of units? For most quantities a unit is necessary to communicate values of that physical quantity. For example, conveying to someone a particular length without using some sort of unit is impossible, because a length cannot be described without a reference used to make sense of the value given. What are […]

Renewable resources include solar energy, wind, falling water, the heat of the earth (geothermal), plant materials (biomass), waves, ocean currents, temperature differences in the oceans and the energy of the tides. What are the importance of renewable resources? THE IMPORTANCE OF RENEWABLE ENERGY They differ from fossil fuels principally […]
What is the direction of the electric field caused by the charge at point P?
What is the direction of the electric field caused by the charge at point P? The magnitude of the electric field E produced by a charged particle at a point P is the electric force per unit positive charge it exerts on another charged particle located at that point. The direction of the electric field […]
Do we see in black and white at night?
Do we see in black and white at night? Sensing Light Both rods and cones are sensitive to light. When it gets dark the cones lose their ability to respond to light. The rods continue to respond to available light, but since they cannot see color, so to speak, everything appears to be various shades […]
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 […]
Is active or passive transport faster?
Is active or passive transport faster? Active transport is a rapid process. Passive transport is a comparatively slow process. What are the 4 methods of passive transport? The rate of passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. […]
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 are the two essential conditions for work done by a force acting on an object?
What are the two essential conditions for work done by a force acting on an object? For work to be done, it is essential that some force is applied to the object and the object displaces from its initial position. If these two conditions are satisfied, then the work is done. So, work done= force […]
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 […]
