A copper pot with mass 0.500 kg contains 0.170 kg of water ata temperature of 20.0ºC. A 0.250-kg block of iron at85.0ºC is dropped into the pot. Find the final temperature, assuming no heat loss to the surroundings
Illustrate the formation of stationary waves in stretched strings and thus deduce the laws of transverse waves in stretched string.
The characteristic of a body by virtue of which the body takes its real configuration when external deforming forces are removed is called as elasticity.
Length Contraction is Invisible This series of animations describes that the relativistic length contraction is invisible.
(a) Two 40 g ice cubes are dropped into 220 g of water in a thermally insulated container. If the water was initially at25°C, and the ice came directly from a freezer at -15°C,what

The vapour pressure of a substance at 20.0 o C is 38.1 kPa and its enthalpy of vaporisation is 49.6 kJ mol -1 . Estimate the temperature at which its vapour pressure is 80.0 k
Refractive index: The most important optical measurement for any transparent material is its refractive index (n). The refractive index is the ratio of the speed of light (c)
WHAT ARE THE PROPERTIES OF MAGNETS?
A section through a magnetic circuit of uniform cross-sectional area 2cm 2 is shown in fi gure. The cast steel core has a mean length of 25cm. The air gap is 1mm w
Resistance in Series: In such a combination the resistors give a single path to the passage of current and similar current passes by each of the resistors.
