Answer:
the minimum thickness (in nm) t = 102.5 nm
Explanation:
t = thickness of the film
n = index of refraction = 1.61
m = order = 1
∝ = wavelength = 330 x 10-9 m
so we have the formula
2nt = m∝
2 (1.61) t = (1) (330 x 10-9)
then...
t = 1.025 x 10-7 m
converting...
t = 102.5 nm
The vector goes from (0,0) to (-5, -5) .C
<h3>How to describe the vector</h3>
From the given graph, trace the point of the arrow.
For y-axis, the arrow is at -5 point
For x-axis, the arrow is at -5 point
The start point of the arrow is at 0 both on the x and y axes.
Thus, the vector goes from the point at (0, 0) and (-5, -5) on the x and y axes respectively.

Answer:
A: The mass would be 250kg
Explanation:
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity.
p= mv
m= p/ v
The explanation to that is:
momentum = mass× velocity
mass= momentum / velocity
