If the cell is shunted by a 2Ω resistor and the balance is obtained across 40 cm of the wire, then the internal resistance of the cell is View Solution Four identical cells each of emf 2V, are joined in parallel providing supply of current to external circuit consisting of two 15Ω...
What do you mean by emf? What are evanescent waves? How does the interference of water waves differ from the interference of electrons? How are they analogous? Define electrostatic. What is meant by "phase" in wave optics? What is meant by a beam?
What is the definition of interia? What is the formula for a capacity? Define the Bernaullis equation. What is the difference between the meaning of measurement and the value of measurement in physics? What is the use of dimensional analysis?
OR The temperature at which the pressure exerted by molecules leaving a liquid equals the pressure exerted by the molecules in the air above it. A free-for-all of molecules leaving the liquid then ensues. Medical, Chemistry, Technology, Environment, Construction, Physics, NASA, Electrical, ...
With the above in mind, we need to examine whether taking numerous measurements of the temperatures of land, sea, and air can provide us with a precise value for the ‘temperature’ of Earth. Earth’s ‘Temperature’ By convention, climate is usually defined as the average of meteorologica...
