Answer: 3.69 × 10^27
Explanation:
Amount of energy required = 7.06 × 10^4 J
Frequency of microwave (f) = 2.88 × 10^10 s−1
Planck's constant (h) = 6.63 × 10^-34 Jᐧs/quantum
Recall ;
Energy of photon = hf
Therefore, energy of photon :
(6.63 × 10^-34)j.s× (2.88 × 10^10)s^-1
= 19.0944 × 10^(-34 + 10) = 19.0944×10^-24 J
Hence, number of quanta required :
(7.06 × 10^4)J / (19.0944 × 10^-24)J
= 0.369 × 10^(4 + 24) = 0.369×10^28
= 3.69 × 10^27
Answer: Thus the volume of the balloon at this altitude is 419 L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 751 mm Hg
= final pressure of gas = 495 mm Hg
= initial volume of gas = 340 L
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
Thus the volume of the balloon at this altitude is 419 L
Answer:
92.2 m
Explanation:
Given that:=
The breadth = 304 mm
Height = 0.014 mm
Let Length = x mm
Volume =
Thus,
Volume =
Also, 1 mm³ = 0.001 cm³
So, volume = 0.004256 cm³
Given that density = 2.7 g/cm³
Mass = 1.06 kg = 1060 g
So,
So,
0.004256*x = 392.59
x = 92243.89 mm
Length of foil = 92243.89 mm = 92.2 m
