Is water Vapour is a greenhouse gas? Water vapor is the most important greenhouse gas. It controls the Earth’s temperature.” It’s true that water vapor is the largest contributor to the Earth’s greenhouse effect. Because these gases are not condensable at atmospheric temperatures and pressures, the atmosphere can pack in much more of these gases […]
Do I need a flare gun on my boat?
Do I need a flare gun on my boat? Boaters must have current dated US Coast Guard-approved day and night signals for all boats operating on coastal and open bodies of water. If operating at night, one electric distress light or three combination day/night red flares are required. Can the Coast Guard search your boat? […]
What makes a sample representative?
What makes a sample representative? A representative sample is a subset of a population that seeks to accurately reflect the characteristics of the larger group. For example, a classroom of 30 students with 15 males and 15 females could generate a representative sample that might include six students: three males and three females. What percentage […]
What are the 3 types of genetic variation?
What are the 3 types of genetic variation? For a given population, there are three sources of variation: mutation, recombination, and immigration of genes. What would happen if there was no genetic variation? Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk […]
Does Salt stay dissolved in water?
Does Salt stay dissolved in water? When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. What is the solution of salt and […]

Which two factors affect the wind and pressure system of an area?
Which two factors affect the wind and pressure system of an area? The two factors that affect the wind and pressure of an area are: latitudes:At the higher latitudes the pressure is high and the air settle down. Temperature:When the temperature is high there will be low pressure and the air rises and when the […]
Why is the motion of a pendulum an example of simple harmonic motion?
Why is the motion of a pendulum an example of simple harmonic motion? because even at large amplitudes there is restoring force pulling the pendulum toward mean position and its acceleration is directly proportional to the displacement. … Why does SHM occur? Simple Harmonic Motion (SHM) is defined as an oscillation whose restoring force is […]
