The acceleration on an object is proportional to the resultant force and inversely proportional to the mass of the object
<h3>Further explanation </h3>Newton's 2nd law explains that the acceleration produced by <em>the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object </em>
∑F = m. a
F = force, N
m = mass = kg
a = acceleration due to gravity, m / s²
Newton's equation shows that the greater the net force applied to an object, the greater the acceleration, conversely the greater the mass of the object, the smaller the object's acceleration.

Answer:
714 nm
Explanation:
Using the equation: nλ=d<em>sin</em>θ
where
n= order of maximum
λ= wavelength
d= distance between lines on diffraction grating
θ= angle
n is 1 because the problem states the light forms 1st order bright band
λ is unknown
d= or 0.0000014 (meters)
sin(30)= 0.5
so
(1)λ=(0.0000014)(0.5)
=0.000000714m or 714 nm
