Answer:
Option C - the angle of refraction is greater than the angle of incidence
Explanation:
Snell's law of refraction states that;
n1 sinθ1 = n2 sinθ2
Where;
n1 is refractive index of incidence medium
θ1 is angle of incidence
n2 is Refractive index of refraction medium
θ2 is angle of refraction
For This question, n1 = 1.5 and n2 = 1.33
Thus;
1.5 sinθ1 = 1.33 sinθ2
Rearranging, we have;
sinθ1/sinθ2 = 1.33/1.5
We know from trigonometry, that sin 0 = 0 and sin 90 = 1. So, as θ approaches 0°, the value of sinθ decreases while as it approaches 90°,the value of sinθ increases.
Thus, by inspection, we can say that the value of the denominator is higher than the numerator.
Thus, θ2 is greater than θ1
So, the angle of refraction is greater than the angle of incidence
Radius of Earth is given as
now here the height from the surface of earth is same as that of radius
now here the acceleration due to gravity at this height is given as
now the force of gravity on the given object will be
<em>so the force of gravity on it is 1.225 N</em>
Dude you gotta rewrite that I have no idea what the question is
Ignoring air resistance, the Kinetic energy before hitting the ground will be equal to the potential energy of the Piton at the top of the rock.
So we have 1/2 MV^2 = MGH
V^2 = 2GH
V = âš2GH
V = âš( 2 * 9.8 * 325)
V = âš 6370
V = 79.81 m/s
Exosphere is the answer . I have done this lesson in my physics class it's exosphere.
