Two holes of unequal diameters $d_1$ and $d_2$ $({d_1} > {d_2})$ are cut in a metal sheet. If the sheet is heated
Both $d_1$ and $d_2$ will decrease
Both $d_1$ and $d_2$ will increase
$d_1 $ will increase, $d_2$ will decrease
$d_1$ will decrease, $d_2$ will increase
Suppose there is a hole in a copper plate. On heating the plate, diameter of hole, would
A bimetallic strip consists of metals $X$ and $Y$. It is mounted rigidly at the base as shown. The metal $X$ has a higher coefficient of expansion compared to that for metal $Y$. When the bimetallic strip is placed in a cold bath:
Two marks on a glass rod $10\, cm$ apart are found to increase their distance by $0.08\, mm$ when the rod is heated from $0\,^oC$ to $100\,^oC$. A flask made of the same glass as that of rod measures a volume $1000\, cc$ at $0\,^oC$. The volume it measures at $100\,^oC$ in $cc$ is
A steel tape gives correct measurement at $20^o C$. A piece of wood is being measured with the steel tape at $0^o C$. The reading is $25 \,\,cm$ on the tape, the real length of the given piece of wood must be:
The coefficient of apparent expansion of a liquid when determined using two different vessels $A$ and $B$ are $\gamma_1$ and $\gamma_2$ respectively. If the coefficient of linear expansion of vessel $A$ is $\alpha$, the coefficient of linear expansion of vessel $B$ is
