The answer is thermocol as Y is ice and thermocol is a bad conductor of heat.

Ans 14:

Class : Class 8
C. of course

Ans 15:

Class : Class 7
Since ''y'' is ice ,thermocol is the only material from the following which will prevent the ice from melting.

Ans 16:

The correct answer is 'd'. M/s^2 or metre per second square. That is because the formula for acceleration is change in velocity /time. The SI unit of velocity is m/s (as it is displacement /time) and the SI unit of time is second. So the SI unit of acceleration is m/s/s which can also be written as m/s^2
