The vacuum layer will prevent heat losses due to conduction and convection completely as it will provide no medium for these phenomena.
P waves<span> are produced by all earthquakes. They are compression </span>waves<span> that </span>form <span>when rocks break due to pressure in the Earth. S </span>waves<span> are secondary </span>waves<span> that are also created during an earthquake. They travel at a slower speed than the </span>p-waves<span>.
S waves are the waves that come after the earthquake and P waves

Answer:
c. 98 W
Explanation:
= initial power delivered by bulb at initial temperature = 40 W
= initial temperature of filament = 2000 K
Now the temperature of filament of the bulb rises
=Final power delivered by bulb at higher temperature
= Final higher temperature of filament = 2500 K
As per Stefan's law, the power delivered by the bulb depends directly on fourth power of the temperature. hence we can write
