Are forests helping in the fight against climate change answers? The negative values of annual NEE show that this forest is a carbon sink, because more CO2 is being removed from the atmosphere via photosynthesis than is returning via decomposition and respiration. This suggests that forests are helping to reduce the total CO2 in the […]
What is an unknown resistance?
What is an unknown resistance? Your unknown resistance is . between D and B points denote voltage drop across a Galvanometer. Now, change R2 variable resistor and tune it until the Galvanometer shows zero deflection. Once the Galvanometer shows zero deflection, the value of R2 is noted and hence unknown resistance can be known by […]
Which force pulls objects to the ground?
Which force pulls objects to the ground? Gravitational force Which forces act on a skydiver who is falling at terminal velocity? As the skydiver gains speed, their weight stays the same but the air resistance increases. There is still a resultant force acting downwards, but this gradually decreases. Eventually, the skydiver’s weight is balanced by […]
What happens when humidity reaches 100 %?
What happens when humidity reaches 100 %? When relative humidity reaches 100 percent or is saturated, moisture will condense, meaning the water vapor changes to liquid vapor. Thus, the saturation level of air is related to the air’s temperature. As air temperature increases (or becomes warmer), more water remains in a gas phase. What happens […]
Why you are interested in a particular career?
Why you are interested in a particular career? Example: “I’m interested in this job because I can see that, in this role, my skills could help solve this problem within your company. I also see an opportunity for me to learn and grow these skills, so we both would benefit personally, professionally, and financially. What […]
Is solar power renewable?
Is solar power renewable? Solar energy is the cleanest and most abundant renewable energy source available, and the U.S. has some of the richest solar resources in the world. Will we ever run out of solar energy? Solar energy is a renewable resource, meaning it won’t ever run out or be in short supply. Solar […]
Is a Kelvin hot or cold?
Is a Kelvin hot or cold? The Kelvin scale is similar to the Celsius scale. Zero degrees is defined as the freezing point of water in the Celsius system. However, the zero point in the Kelvin scale is defined as the coldest possible temperature, known as “absolute zero”. Absolute zero is –273.15° C or –459.67° […]
Are the polar caps melting?
Are the polar caps melting? North Polar ice cap melting The area covered by sea ice ranges between 9 and 12 million km2. According to the National Snow and Ice Data Center, “since 1979, winter Arctic ice extent has decreased about 4.2 percent per decade”. How long will it take for polar ice caps to […]
Can you die on an escalator?
Can you die on an escalator? As a result, there does not currently exist a national system for recalling defective escalator parts. Although there appears to be a glaring lack of oversight, escalator-related deaths in the United States are actually quite rare – according to the National Library of Medicine. Which is the world’s shortest […]
