What is action spectrum and absorption? The absorption spectrum indicates the wavelengths of light absorbed by each pigment (e.g. chlorophyll) The action spectrum indicates the overall rate of photosynthesis at each wavelength of light. It is a graphical representation of the amount of light of different wavelengths absorbed by a pigment. Which pigments are most […]
What force keeps a bicycle wheel from flying off?
What force keeps a bicycle wheel from flying off? Another idea you should know about in order to understand a gyroscope is centripetal force. This is a force that pulls on an object that is spinning around another object and keeps it from flying off in a straight line. Why is a rotating bicycle wheel […]
How does the population affect pollution?
How does the population affect pollution? Emissions do increase as population increases, but not as fast. As the population of a city increases, the emissions also increase, but the per capita emissions decrease. The monetized damage value of emissions, which represents the impact of pollution, grows as the city grows. Do you see the high […]
How much activity is considered active?
What are the 4 methods of heat loss?
What are the 4 methods of heat loss? The body loses heat through: Evaporation of water from your skin if it is wet (sweating). Radiation (similar to heat leaving a woodstove). Conduction (such as heat loss from sleeping on the cold ground). Convection (similar to sitting in front of a fan or having the wind […]
How much energy does a geothermal heat pump use?
How much energy does a geothermal heat pump use? Geothermal heat pumps don’t generate heat — they just transfer it from the ground into your home. For every 1 unit of energy used to power your geothermal system, on average 4 units of heat energy are supplied. How much land do you need for geothermal […]
What are the problems with DNA evidence?
What are the problems with DNA evidence? DNA evidence is only as reliable as the procedures used to test it. If these procedures are sloppy, imprecise, or prioritize particular results over accuracy, then the so-called “DNA evidence” they produce cannot be a trustworthy basis for a conviction. What are the 4 basic steps of DNA […]
How does the four subsystem interact with each other?
How does the four subsystem interact with each other? The geosphere has four subsystems called the lithosphere, hydrosphere, cryosphere, and atmosphere. Because these subsystems interact with each other and the biosphere, they work together to influence the climate, trigger geological processes, and affect life all over the Earth. Why are the earth’s spheres important? Earth […]
What era of the universe are we in?
What era of the universe are we in? Stelliferous Era This is the current era, in which matter is arranged in the form of stars, galaxies, and galaxy clusters, and most energy is produced in stars. Stars will be the most dominant objects of the universe in this era. Massive stars use up their fuel […]
How can electric force be reduced?
How can electric force be reduced? Inverse relationships are common in nature. In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. What are the 2 factors the […]
