Answer:
T = 51.25°C
Explanation:
Applying the law of conservation of energy, we get:
where,
m₁ = mass of cold water = 175 g
m₂ = mass of hot water = 125 g
T = Final temperature of the mixture = ?
Therefore,
<u>T = 51.25°C</u>
True.
As the length of the conductor increases, so also the resistance to the flow of current increases along the conductor.
Answer:
ok
Explanation:
post the question and we'll help :)
Wave speed = frequency * wavelength
We need to rearrange this equation because we are finding the wavelength :
Wavelength = wave speed / frequency
To rearrange it, I just divided it by frequency so that wavelength was the subject.
Now, input these numbers into this equation :
Wavelength = wave speed / frequency
Wavelength = 25 / 5
Wavelength = 5m
