Question
A spherical shell rolls down a plane inclined at $30^{\circ}$ to the horizontal. What is its acceleration ?
✓

Answer

The acceleration of the spherical shell, $\mathrm{a}=\frac{3}{5} \mathrm{~g} \sin \theta=0.6 \mathrm{~g} \sin 30^{\circ}=0.6 \mathrm{~g} \times \frac{1}{2}=0.3 \mathrm{~g} \mathrm{~m}$

There are different types of shielding available like electrical and accoustic shielding apart from magnetic shielding discussed above. Electrical insulator functions as an electrical barrier or shield and comes in a wide array of materials. Normally the electrical wires used in our households are also shielded. In case of audio recording it is necessary to reduce other stray sound which may interfere with the sound to be recorded. So the recording studios are sound insulated using acoustic material.
