The closest refractive index to the one observed is that of rayon, about 1.51. Therefore, the fiber is likely from the suspect's shirt.
Answer:
A.)
Explanation:
Because you didn't add anything or take anything away.
Answer:
5.0 m/s
Explanation:
The horizontal motion of the salmon is uniform, so the horizontal component of the salmon's velocity is constant and it is
where u is the initial speed and . The horizontal distance travelled by the salmon is
where d = 1.95 m and t is the time needed to reach the final point.
Re-arranging for t,
(1)
Along the vertical direction, the equation of motion is
where:
y = 0.311 m is the final height reached by the salmon
h = 0 is the initial height
is the vertical component of the initial velocity of the salmon
is the acceleration of gravity
t is the time
Substituting t as found in eq.(1), we get the equation
and we can solve this formula for u, the initial speed of the salmon:
The distance of the object from the lens is 3.12 cm.
<h3>What is magnification?</h3>
Magnification is the process of of enlarging an apparent size of an object.
<h3>Object distance</h3>
The object distance is calculated using the following lens formula;
where;
- M is the magnification
- V is the image distance
- U is object distance
Thus, the distance of the object from the lens is 3.12 cm.

Answer:
Explanation:
As we know that
E = 1.8 kV/mm
now we know that electric field between the plated of capacitor is given as
now we will have
now we have
now we have area of the plates of capacitor
