P1v1/t1 = p2v2/t2
p(0.5 m^3)/(20+273 K) = pv2/(45+273 K)
find v2
Answer:
Explanation:
When water droplet condenses on the outer wall of glass of ice , it releases heat equal to mass x latent heat of condensation of water . This heat reaches the ice melting inside glass . Due to this heat , the melting process is accelerated .
Hence the process of melting gets accelerated when water droplet condenses on the outer wall of glass containing mixture of ice and water .
Answer: E) all of the above
Explanation:
Frequency is the number of vibrations in one second. It is also defined as the number of crests that pass a point in a given time.
The frequency and the wavelength has an inverse relationship.
Frequency is measured in cycles per second or Hertz(Hz).
The relationship between wavelength and frequency of the wave follows the equation:
where,
= frequency of the wave
c = speed of light
= wavelength of the wave
Thus all the given statements are true.
Answer:
Leak 1 = 3.43 m/s
Leak 2 = 2.42 m/s
Explanation:
Given that the top of the boot is 0.3 m higher than the leaks.
Let height H = 0.3m and the acceleration due to gravity g = 9.8 m/s^2
From the figure, the angle of the leak 1 will be approximately equal to 45 degrees. While the leak two can be at 90 degrees.
Using the third equation of motion under gravity, we can calculate the velocity of leak 1 and 2
