Find the approximate change in volume V of a cube of side 5m caused by increasing its side length by 2%.

A closed pipe of length 1 m emits the fundamental note. What is the percentage change in the frequency when the temperature is changed from 30^@C" to "45^@C.

To increase the length of brass rod by 2% its temperature should increase by (alpha = 0.00002 "^(@)C^(-1)) a) 800 degree C b) 900 degree C c) 1000 degree C d) 1100 degree C

A metal rod lenth L_(0) whose coefficient of linear expansion alpha = 10^(-3) ^(0)C^(-1) is heated such that its temperature changes by 1000K assuming alpha is constant during the temperature change (e =2.7) . Which of the following statements are true

The coefficient of linear expansion of a rod of length 1 m, at 27^@C , is varying with temperature as alpha = 2/T unit (300 K le T le 600 K) , where T is the temperature of rod in Kelvin. The increment in the length of rod if its temperature increases from 27^@C to 327^@C is

Coefficient of thermal expansion of a wire varies with temperature T as alpha = 1.6 xx 10^(-6) T , where T is temperature in degree Celsius. If the length of wire is 10 m at 0^@C , what is the change in length of wire (in mm), when its temperature is raised to 25^@C ?

The length of steel rod exceeds that of a brass rod by 5 cm. If the difference in their lengths remains same at all temperature, then the length of brass rod will be: ( alpha for iron and brass are 12xx10^(-6)//^(@)C and 18xx10^(-6)//^(@)C , respectively)

The length of s steel rod exceeds that of a brass rod by 5 cm. If the difference in their lengths remains same at all temperature, then the length of brass rod will be: ( alpha for iron and brass are 12xx10^(-6)//^(@)C and 18xx10^(-6)//^(@)C , respectively)
