Choose the correct statement from following.
1 Not all basic laws of physics are universal
2 Conservation laws have a deep connection with symmetries of nature
3 There are four to six fundamental forces in nature that govern the diverse phenomena of the world
4 Physics can generate new technology but new physics cannot come out from technology
Explanation:
B A conservation law is a hypothesis based on observations and experiments. - Conservation of law is a principle that states that a certain physical property does not change in the course of time within an isolated physical system. - Conservation laws have a deep connection with symmetries of nature.

One angstrom \((\AA)\) is equal to:
1 \(10^{-6} \mathrm{~mm}\)
2 \(10^{-7} \mathrm{~mm}\)
3 \(10^{-8} \mathrm{~mm}\)
4 \(10^{-9} \mathrm{~mm}\)
Explanation:
B One angstrom is equal to \(=1 \times 10^{-7} \mathrm{~mm}\) \(\because 1 \AA= 10^{-10} \mathrm{~m}\) \(=10^{-10}\left(10^{3}\right) \mathrm{mm} \quad\left\{1 \mathrm{~m}=10^{3} \mathrm{~mm}\right\}\) \(=10^{-7} \mathrm{~mm}\)

In which physical quantity, maximum percentage change will be observed, when a copper sphere is heated?
1 radius
2 area
3 volume
4 length
Explanation:
C When a copper sphere is heated then maximum percentage change will be observed in its volume. - Change in Area \((\mathrm{A})=4 \pi \mathrm{r}^{2}\) \(\therefore \frac{\Delta \mathrm{A}}{\mathrm{A}}=2\left(\frac{\Delta \mathrm{r}}{\mathrm{r}}\right)=\) Two times the percentage change - Change in volume \(\mathrm{V}=\frac{4}{3} \pi \mathrm{r}^{3}\) \(\therefore \frac{\Delta \mathrm{V}}{\mathrm{V}}=3\left(\frac{\Delta \mathrm{r}}{\mathrm{r}}\right)=3\) times the percentage change in radius So, maximum change will occur in volume, when a copper sphere is heated.
