a steel rod when measured with a zinc scale both being at 25 degree Celsius appear to be one meter long.if the zinc scale is correct at 0 degree Celsius, what is the actual length of the rod at 0 degree Celsius? [linear expansivity of steel=12*10^-6 /degree C
linear expansivity of zinc=26*10^-6/degree Celsius]
a steel rod was found to be 2 meters long at 20 degree celcious.when measured by a standard brass scale of length 1 meter at 0 degree celcious.find out the length of the same steel rod at 50 degree celcious as measured by the same
An alumium rod when measured with a steel scale both being at 25 degree celcius appears to be 1 meter long. If the scale is correct at 0 degree celcius, what is the true length of the rod at 25 degree celcius? What wull be the
A sample of zinc with a mass of 14g was heated to 98 degree celsius in boiling water and then dropped into a beaker containing 4.5x10^4ng of water at 25 degree celsius. when the water and metal came to thermal equilibrium, the
What volume of 15 degree celsius water must be added to a 1.2KG piece of stainless steel at 85 degree celsius so that the final temperature is 35 degree celsius. assume the container in which the mixing takes place is perfectly
How much thermal energy will flow per hour through a copper rod 5.00 cm in diameter and 1.50 m long, if one end of the rod is maintained at a temperature of 22.5 degree Celsius and the other end at 20.0 degree Celsius?
A rod of mass 4.3 kg and length 4.3 m hangs from a hinge as shown in Figure P9.28. The end of the rod is then given a “kick” so that it is moving at a speed of 2.3 m/s. How high will the rod swing? Express your answer in terms
In the metric system there are two official temperature scales: degree Celsius and kelvin. The kelvin temperature scale is obtained by shifting the Celsius scale so of any heat whatsoever. An equation about the relationship
A steel rod of length 1 m is welded to the end of an aluminum rod of length 2 m (lengths measured at 23 °C). The combination rod is then heated to 198 °C. What is the length of the combination rod at 198 °C? (The linear
95.0 mL of H_2O is initially at room temperature (22 degree C). A chilled steel rod at 2 degree C is placed in the water. If the final temperature of the system is 21.3 degree C, what is the mass of the steel bar?
