<h2>
Answer: 1.22 × 10⁻¹ m</h2>
<h3>Explanation:</h3>
Wavelength = Speed of Light ÷ Frequency
= (2.99 × 10⁸ m/s) ÷ ( 2.45 × 10⁹ /s)
= 1.22 × 10⁻¹ m
The wavelength of a light of frequency 2.45 × 10⁹ /s is 1.22 × 10⁻¹ m.
<u>Notes:</u>
Hz ≡ /s
Answer : The temperature in degree Celsius and Kelvin is, respectively.
Explanation :
The conversion used for the temperature from Fahrenheit to degree Celsius is:
where,
= temperature in Fahrenheit
= temperature in centigrade
The conversion used for the temperature from degree Celsius to Kelvin is:
where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in Fahrenheit is, 130
Now we have to determine the temperature in degree Celsius.
Now we have to determine the temperature in Kelvin.
Therefore, the temperature in degree Celsius and Kelvin are,
I had this quiz too. The answer is carbon, hydrogen, oxygen. Hope this helps!
D. More heat is given off then is put into the reaction
