What is the density of the baseball?
2 answers:
The density of the baseball is
Explanation:
The density of an object is given by the equation
where
m is the mass of the object
V is its volume
For the baseball in this problem, we have:
m = 350 g is its mass
is the volume
Substituting into the equation, we find the density:
Therefore, the ball's density is outside the acceptable range.

<h3>What is diffraction grating?</h3>A diffraction grating is a type of optical instrument obtained with a continuous pattern. The pattern of the diffracted light by a grating depends on the structure and number of elements present.
The given data in the problem is
is the angle formed between the path of the incident light and the diffracted light = 9. 2°
λ is the wavelength of the light=490nm=4.9
N is the number of lines per mm in the diffraction grating=?
n is ordered = 1
The formula for the diffraction grating is;
The number of lines per mm is found as;
Hence the number of lines per mm in the diffraction grating is 326.
