How is oxygen maintained in the atmosphere? The balance of oxygen and carbondioxide is maintained in the atmosphere by the oxygen released by plants during photosynthesis and carbondioxide released by human,animals etc. in the atmosphere. The balance of oxygen and carbondioxide is made due to respreration and photosinthesis. How did we get oxygen in our […]
Why are fair weather predictions sometimes incorrect?
Why are fair weather predictions sometimes incorrect? Answer Expert Verified 2) The atmosphere always changes with natural disasters occurring such as pollutants in the air that make forecasting difficult. 3) Most of the times meteorologists base their forecasts on probability. Because of differences in the climate, those temperatures are not the same, so errors occur. […]

Which metal is used to make car bodies?
Which metal is used to make car bodies? The main materials used for making cars, parts and components, along with future trends, are steel, aluminum, magnesium, copper, plastics and carbon fibers. The prime reason for using steel in the body structure is its inherent capability to absorb impact energy in a crash situation. What is […]
How do I calculate simple interest?
Which way does current flow?
Which way does current flow? The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite […]

How is energy transferred from one object to another?
How is energy transferred from one object to another? The two ways that energy can be transferred are by doing work and by heat transfer. Can an object have work? In the physics sense, work is never something an object has. It is only something that one object does to another. Work changes the amount […]
