To solve this problem it is necessary to apply the concepts related to angular resolution, for which it is necessary that the angle is

Where
d = Diameter of the eye
n = Index of refraction
D = Distance between head lights
= Wavelength
Replacing with our values we have that


Using the proportion of the arc length we have to

Where L is the maximum distance, therefore


Therefore the maximum distance from the observer that the two headlights can be distinguished is 12.77km
The Law of the Conservation of Energy is stating that the total mechanical energy is always conserved or in simpler terms, not used or saved.
Answer:
D. When the dense, positive alpha particle passes close to a positive nucleus of gold, the alpha particle repels and hits the screen at point X.
Explanation:
The power required is 30 Watt.
Let us recall that power is defined as the rate of doing work. Hence, we can write as follows;
Power = Work done/ time taken
Now;
work done = Force × distance
Force = 30.0 N
Distance = 10.0 m
work done = 30.0 N × 10.0 m = 300 J
The power expended = 300 J/10.00 s = 30 Watt
