Do fountains use a lot of electricity? Water fountains don’t use a lot of electricity, but they can become pricier if you use high-end pumps. Less water and horsepower will reduce electrical consumption, but it’ll also lessen the effect of the fountain. Most water fountains cost less than $50 per month to operate several hours […]
What gas diffuses the fastest?
What gas diffuses the fastest? The rate of effusion for a gas is inversely proportional to the square-root of its molecular mass (Graham’s Law). The gas with the lowest molecular weight will effuse the fastest. The lightest, and therefore fastest, gas is helium. Which gas diffuses faster hydrogen or helium? Graham’s law of diffusion states […]
How does energy crisis affect the economy?
How does energy crisis affect the economy? Lower GDP growth and high inflation in recent years has also been attributed to shortfall in energy supply. As a result of decline in energy supply, new industrial units cannot be opened, rather the existing industrial units are gradually being closed. Energy also impacts unemployment/employment. How did the […]

What is energy in a food web?
What is energy in a food web? Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of […]
How do you collect gas over water?
How do you collect gas over water? A common way to determine the amount of gas present is by collecting it over water and measuring the height of displaced water; this is accomplished by placing a tube into an inverted bottle, the opening of which is immersed in a larger container of water. Why do […]
Which of the following measures is most effective for preventing pulmonary embolism in patients who are recovering from major surgery?
Which of the following measures is most effective for preventing pulmonary embolism in patients who are recovering from major surgery? Using a blood-thinning drug is the most effective way to prevent VTE, particularly after major surgery, even if a patient is walking and using SCDs. What is the major role of neutrophils in acute respiratory […]
What causes deep currents to form?
What causes deep currents to form? Deep ocean currents (also known as Thermohaline Circulation) are caused by: The sinking and transport of large masses of cool water gives rise to the thermohaline circulation, which is driven by density gradients due to variations in temperature and salinity. The earth’s rotation also influences deep ocean currents. What […]
What are 3 factors that can cause a loss of traction?
What are 3 factors that can cause a loss of traction? In winter, loss of traction can occur anytime, anywhere – when going too fast around a corner, when dry conditions quickly change to rain or ice, when parked incorrectly on an icy hill, or applying too much brake (causing the wheels to lock). Any […]
Why is it important to develop cardiovascular fitness early in life?
Why is it important to develop cardiovascular fitness early in life? Improving cardiovascular fitness can reduce your risk of developing heart disease by increasing the efficiency of your heart, lungs, and blood vessels. The easier it is to pump blood through your body, the less taxing it is on your heart. What are 3 physical […]
