Answer:
n₁ > n₂.
prisms are made of glass with refractive index n₂ = 1.50, so the fluid that surrounds the prism must have an index n₁> 1.50
Explanation:
Total internal reflection occurs when the refractive index of the incident medium the light is greater than the medium to which the light is refracted, let's use the refraction equation
n₁ sin θ₁ = n₂ sin θ₂
the incident medium is 1, at the limit point where refraction occurs is when the angle in the refracted medium is 90º, so sin θ₂ = 1
n₁ sin θ₁ = n₂
sin θ₁ = n₂ / n₁
We mean that this equation is defined only for n₁ > n₂.
In our case, for the total internal reflection to occur, the refractive incidence of the medium must be greater than the index of refraction of the prism.
In general, prisms are made of glass with refractive index n₂ = 1.50, so the fluid that surrounds the prism must have an index n₁> 1.50
Answer:
it is the 3rd answer choice
Answer:
Displacement
Explanation:
An object exhibiting simple harmonic motion, the restoring force is directly proportional to the displacement of the object. The direction of direction of the force is in opposite direction of the displacement. It is given by :

k is the spring or force constant
x is the displacement
So, the correct option is (b) "displacement".
Answer:
t=67.7s
Explanation:
From this question we know that:
Vo = 6m/s
a = 1.8 m/s2
D = 1500m
And we also know that:
Replacing the known values:
Solving for t we get 2 possible answers:
t1 = -44.3s and t2 = 67.7s Since negative time represents an instant before the beginning of the movement, t1 is discarded. So, the final answer is:
t = 67.7s
Answer:
q = -7.691 ×
C
so magnitude of charge is 7.691 ×
C
and negative sign mean charge is negative potential
Explanation:
given data
electric potential = −2.36 V
distance = 2.93 mm = 2.93 ×
m
to find out
What are the sign and magnitude of a point charge
solution
we know here that electric potential due to charge is
V =
..............................1
here k is coulomb force that is 8.99 ×
Nm²/C² and r is distance and q is charge and V is electric potential
put here all value we get q in equation 1
V = 
-2.36 = 
q = -7.691 ×
C
so magnitude of charge is 7.691 ×
C
and negative sign mean charge is negative potential
