The length L (in centimetre) of a copper rod is a linear function of its Celsius temperature C. In an experiment, if `L" "=" "124. 942` when `C" "=" "20` and `L=" "125. 134` when `C" "=" "110` , express L in terms of C.

The dimension of L//C is equivalent to that of ( L to inductance, C to capacitance)

The L.C.M. of 30 and 45 is

If L is the inductance, C is the capacitance and R is the resistance, then Rsqrt(C/L) . has the dimension

A thin rod, length L_(0) at 0^(@)C and coefficient of linear expansion alpha has its two ends mintained at temperatures theta_(1) and theta_(2) respectively Find its new length .

A steel scale measures the length of a copper rod as l_(0) when both are at 20^(@)C , which is the calibration temperature for the scale . The scale reading when both are at 40^(@)C , is :-

When a capacitor is charged then l_(c) = conduction current l_(d) = displacembet current)

A rod of length L is placed along the X-axis between x=0 and x=L . The linear density (mass/length) rho of the rod varies with the distance x from the origin as rho=a+bx. a.) Find the SI units of a and b b.) Find the mass of the rod in terms of a,b, and L.

The total surface area of a cone of radius r/2 and length 2l , is a) 2pir(l+r) b) pir(l+r/4) c) pir(l+r) d) 2pirl

The co-efficient of thermal expansion of a rod is temperature dependent and is given by the formula alpha = aT , where a is a positive constant at T "in"^(@)C . if the length of the rod is l at temperature 0^(@)C , then the temperature at which the length will be 2l is
