Answer:
Explanation:
we know that for ideal gag we have
pV =nRT
Since volume, gas constant R and T are constant, so we have
n = 0.289 mole
hence mass removed
Answer:
Explanation:
As we know that the magnitude of electric field intensity is given as
now we know that intensity of the wave is given as the product of energy density and speed of the wave
so intensity is the energy flow per unit area per unit of time
so the energy that flows through the area of 0.0259 m^2 in 11.7 s is given as
