What is the god Mars animal? God Symbols for Mars. The wolf is a sacred animal and symbol for the god […]

Is there a way to oxygenate blood without lungs? ECMO stands for extracorporeal membrane oxygenation. The ECMO machine is similar to the heart-lung by-pass machine used in open-heart surgery. It pumps and oxygenates a patient’s blood outside the body, allowing the heart and lungs to rest. On which side of the heart is low in […]

What is value of theta? Theta is a measure of the rate of decline in the value of an option due to the passage of time. It can also be referred to as an option’s time decay. The conventional way to define the trig functions is to start with an acute angle that is an […]

Can anything be smaller than an atom? In physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles. Particle physics and nuclear physics study these particles and how they interact. What […]

What are three benefits of being multicellular? List of Pros of Multicellular Organisms. Intelligence and Evolution. Bigger Is Better. Less Stress Equals A Longer Lifespan. Cells Can Take Care Of Each Other. More Energy Is Needed For Normal Functioning. Infection Becomes A Possibility When Multicellular. Takes Longer To Reach Maturity And To Breed. How do […]

How does a straw work in terms of pressure? A straw works because when you suck the air out of the straw, it creates a vacuum. This causes a decrease in air pressure on the inside of the straw. Since the atmospheric pressure is greater on the outside of the straw, liquid is forced into […]

Why does the US not use A4? Replacing every sign in the entire US road system would be an obscene cost. Updating the paper system would probably need to be done around the same time to A4, causing a disconnect between all printed documents in the US from this year into the next several. What […]

What will show Tyndall effect? 1) salt solution 2) milk 3) copper sulphate solution 4) starch solution. The Tyndall effect is the mechanism in which the particles in a colloid scatter the rays of light that are directed at them. All colloidal solutions and some very fine suspensions exhibit this effect. What is Tyndall effect […]

Why does voltmeter read 0? o If there is no source of electricity or resistance between the connections of the voltmeter it will read zero, since no potential difference exists between the two points. Is EMF equal to voltage? Emf is not a force at all; it is a special type of potential difference. To […]

What is the work done when 0.5 mole of methane? Hence, the amount of work done is +2494 J. How much energy is released if 0.5 mole of methane is burned? The molar mass of methane is 16 g/mole, so burning methane will release (810 kJ/mole) / (16g/mole) = about 51 kJ/g fuel burned. What […]
