Condensation does not effect the temperature of the area, condensation is the product the temperature difference between an object and the area it is in
Answer:
Statement 1 and 3 are correct.
Explanation:
1. The mass moves downward, so the net acceleration of the block is straight downward.
2.The mass is sliding through the globe, so only the force of gravity is acting on the mass which pulls it in downward direction. The force of gravity has two components [mg sin∅] and [mg cos∅].

Answer:
Δλ = 3*10⁻³ m.
Explanation:
- At any wave, there exists a fixed relationship between the speed of the wave, the wavelength, and the frequency, as follows:

where v is the speed, λ is the wavelength and f is the frequency.
- Rearranging terms, we can get λ from the other two parameters, as follows:

- Since v is constant for sound at 343 m/s, we can find the different wavelengths at different frequencies, as follows:


- The difference between both wavelengths, is just the difference between (3) and (4):

⇒ Δλ = 3*10⁻³ m.
Answer:
1.9 s
Explanation:
We are given that
Length of cable=l=15 m
We have to find the time you have to move out of the way.
We know that
Time period,T=
Where g=
By using the formula


Time you have to move out

Hence,time you have to move out of the way=7.77 s
