Answer : The frequency decreases by a factor of 2.
Explanation :
Given that the wave travels at a constant speed. The speed of the wave is given as :
Where
υ is the frequency of the wave
and λ is the wavelength of the wave.
In this case, the speed is constant. So, the relation between the frequency and the wavelength is inverse.
If the wavelength increases by a factor of 2, its frequency will decrease by a factor of 2.
Hence, the correct option is (A) " The frequency decreases by a factor of 2 ".
Answer:
15.01 Liters
Explanation:
T₁ = Initial temperature = 25°C = 298.15 K
T₂ = Final temperature = 100°C = 373.15 K
V₁ = Initial volume = 12 mL
Here, pressure is constant so we apply Charles Law
∴ Final volume at 100°C is 15.01 Liters.
Answer:
There are eight planets in our Solar System.

Answer:
c
Explanation:
just trying to follow basic grammar.
The color of light that a star emits is somewhat related to its age, whereas the color of light that we actually <em>observe</em> from a star is related to the speed at which it's moving with respect to us.
