Answer:
464.8 nm
Explanation:
The second wavelength of light can be calculated using the next equation:
<u>Where:</u>
<em>λ : is the wavelength of light</em>
<em>x: is the distance from the central maximum</em>
<em>d: is the distance between the spots </em>
<em>L: is the lenght from the screen to the bright spot</em>
For the first wavelength of light we have:
(1)
For the second wavelength of light we have:
(2)
By entering equation (1) into equation (2) we have:
Therefore, the second wavelength is 464.8 nm
I hope it helps you!
Hey there,
Your correct answer would be 30kg.
450 = m × 15 or also 450/15=m.
Hope this helps.

Answer:
The correct degree of precision is 272.94 g.
Explanation:
Precision : It is defined as the closeness of two or more measurements to each other.
For Example: If you weigh a given substance five times and you get 2.7 kg each time. Then the measurement is said to be precise.
Level of precision is determined by the maximum number of decimal places.
In the given figure, the value of mass of object is 280 g. From the given options we conclude that the 272.94 g is more close to 280 g and has maximum number of decimal places. So, 272.94 g measurement is said to be precise.
Therefore, the correct degree of precision is 272.94 g.
