The speed of light in vacuum is 3 x 10^8 m/s. That means in one second it travels 300000000 metres. As we know, in one year, there are 365 days; in each day there are 4 hours; in each hour there are 60 minutes and in each minute there are 60 seconds. Therefore, the distance […]
What are the dimensions of angle,specific heat,heat,latent heat,frequency,charge,potential difference,resistance? Angle does not have any dimension as it is a pure ratio Dimensions of Specific heat = [M0L2T-2K-1] Heat has the same dimensional formula as that of energy [ML2T-2] Latent heat is the heat energy required to convert unit mass of a substance from one state…… Continue reading Dimensions of angle, specific heat, heat, latent heat, frequency, charge, potential difference, resistance.
Shalini asked: How to do calculation in the physics practical(capillary rise method)..how to measure the diameter of the capillary tube? A Travelling Microscope A travelling microscope is used to determine small distance to an accuracy of 0.001 cm. The measurement principle is based on the principle of vernier. In a typical travelling microscope, the main…… Continue reading Physics Practical:: Measurement of diameter of capillary tube using travelling microscope.
