What is the blue wire in a light fixture? The blue wire is the hot wire for the ceiling fan light fixture. The ceiling fan motor does not have a ground wire. What is the blue wire in headphones? Usually red wires are the right audio channel and blue wires are the left audio channel. […]
Why is the atmosphere essential for life?
Why is the atmosphere essential for life? Atmosphere is very important for sustaining life: It contains various gases like O2, CO2, N2 which are required for various life processes by plants and animals. (ii) gas is used by plants to prepare food by the process called photosynthesis (iii) Oxygen is required for burning, combustion and […]
Are greenhouse gases good or bad?
Are greenhouse gases good or bad? The greenhouse effect is a good thing. It warms the planet to its comfortable average of 59 degrees Fahrenheit (15 degrees Celsius) and keeps life on earth, well, livable. Without it the world would be a frozen, uninhabitable place, more like Mars. Why is greenhouse gas bad? Greenhouse gases […]
How does the angle of deviation depends on the refracting angle of the prism?
How does the angle of deviation depends on the refracting angle of the prism? The angle of deviation (δ) increases with the increase in the angle of prism (A). What is the angle of deviation when angle of incidence is 60? Answer. The angle of deviation will be 60° only. As refracted ray goes strainght […]
What happens if you breathe in volcanic ash?
What happens if you breathe in volcanic ash? Inhalation of volcanic ash can be very detrimental to human health, due to the harmful aerosols and poisonous gases the ash is made up of. Health effects inlcude respiratory problems, eye problems, and skin irritiation. One long-term effect of volcanic ash is silicosis. How dangerous is ash […]
Which layer is closest to space?
Which layer is closest to space? Layers of Earth’s Atmosphere exosphere—contains few particles that move into and from space. exobase—the lower boundary of the exosphere. thermosphere—temperature increases with height. The International Space Station orbits Earth in this layer. mesopause—the boundary between the mesosphere and the thermosphere; the coldest place on Earth. What layer are satellites? […]
What are the limitations of capture-recapture?
What are the limitations of capture-recapture? Mark / Recapture Techniques These techniques have a number of limitations: The animal usually needs to be captured to be marked, which may injure it, or alter its behaviour pattern. The mark used may harm the animal – for example a dot of a particular paint may turn out […]
What is an example of mutation in evolution?
What is an example of mutation in evolution? Even deleterious mutations can cause evolutionary change, especially in small populations, by removing individuals that might be carrying adaptive alleles at other genes. Figure 2: The history of the gray treefrog, Hyla versicolor, is an example of mutation and its potential effects. What is the most common […]
When you have a plane determined by 3 points how do you calculate the normal vector?
How do you find acceleration without time?
How do you find acceleration without time? If the acceleration is constant, it is possible to find acceleration without time if we have the initial and final velocity of the object as well as the amount of displacement. The formula v2=u2+2as where v is the final velocity, u is the initial velocity, a is the […]
