Which is better oxygen tank or oxygen concentrator? Oxygen concentrators are portable and easy to use and are thus better than oxygen cylinders. Although at Rs 40,000-Rs 90,000, they are more expensive than cylinders (Rs 8,000-20,000), they require very minimal maintenance. Will low oxygen make you tired? You’ll develop low blood oxygen levels, a condition […]

Does altitude affect cooking time? At high altitudes: Air pressure is lower, so foods take longer to cook. Temperatures and/or cook times may need to be increased. Water boils at a lower temperature, so foods prepared with water (such as pastas and soups) may take longer to cook. How do you bake at elevation? High-Altitude […]

What is the type of relationship between current and potential difference? The current in a circuit is directly proportional to the electric potential difference impressed across the circuit and inversely proportional to the resistance of the circuit. What is potential difference unit? The potential difference between points A and B, VB – VA, is defined […]

How do we develop our identity? Building a strong sense of self Define your values. Values and personal beliefs are fundamental aspects of identity. Make your own choices. Your decisions should, for the most part, primarily benefit your health and well-being. Spend time alone. Consider how to achieve your ideals. Can we change our identity? […]

Why is nuclear energy bad? Nuclear energy produces radioactive waste A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years. Is nuclear energy safe? […]

Is it possible for a heat engine to operate without rejecting any waste heat to a low temperature reservoir explain? It is not possible for a engine to operate without rejecting any waste heat to a low temperature reservior. It violates the second law of thermodynamics, the operation of a heat engine a low temperature […]

Which two factors are needed to calculate the velocity of an object? The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is a physical vector quantity; both magnitude and direction are needed to define it. Speed, the […]
