Answer:
6.32 m/s 18.43° northeast
Explanation:
We express the velocity of hawk as:
We consider positive x towards east and positive y due north. So the magnitude is simply the square root of the square components:
≈
And the angle with respect to the east should be with:
Broad questions that we can answer by doing this experiment are <em><u>the effects of electric current</u></em>
<h3>Further explanation</h3>Electric current is the amount of electric charge that flows each unit of time
Electric current occurs due to the movement of electrons due to the difference in potential or voltage (from high potential to low potential) between two points
Electrons will flow through the conducting wire that functions as a conductor
Ohm's Law states that
<em>The potential difference is proportional to the electric current as long as the resistance is constant</em>
A simple electrical circuit consists of a voltage source (battery) and a lamp
Ampermeters to measure the strength of the current, must be installed in series with the load to be measured
By changing the voltage source, with constant resistance from a conductor, different current measurements will be obtained. The greater the voltage, the greater the resulting current.

Answer:
Difference in the angle of refraction = 0.3°
41.04° is the minimum angle of incidence.
Explanation:
Angle of incidence = 38.0°
For yellow light :
Using Snell's law as:
Where,
Θ₁ is the angle of incidence
Θ₂ is the angle of refraction
n₁ is the refractive index for yellow light which is 1.523
n₂ is the refractive index of air which is 1
So,
Angle of refraction for yellow light = sin⁻¹ 0.9377 = 69.67°.
For green light :
Using Snell's law as:
Where,
Θ₁ is the angle of incidence
Θ₂ is the angle of refraction
n₁ is the refractive index for green light which is 1.526
n₂ is the refractive index of air which is 1
So,
Angle of refraction for green light = sin⁻¹ 0.9395 = 69.97°.
The difference in the angle of refraction = 69.97° - 69.67° = 0.3°
Calculation of the critical angle for the yellow light for the total internal reflection to occur :
The formula for the critical angle is:
Where,
is the critical angle
is the refractive index of the refractive medium.
is the refractive index of the incident medium.
n₁ is the refractive index for yellow light which is 1.523 (incident medium)
n₂ is the refractive index of air which is 1 (refractive medium)
Applying in the formula as:
The critical angle is = sin⁻¹ 0.6566 = 41.04°
