Answer:
Option D: 1.5in in front of the target
Explanation:
The object distance is 
.
Because the surface is flat, the radius of curvature is infinity .
The incident index is 
and the transmitted index is 
.
The single interface equation is 
Substituting the quantities given in the problem,
The image distance is then 
Therefore, the coin falls 
in front of the target
That type of bending is called "diffraction" of waves.
Answer:
241,274.32 inches
Explanation:
How far will he travel if the rear wheel makes 1200 revolutions on the road?
Since the rear wheel makes one revolution in the distance of a circumference of a circle, C with diameter, d = 16 inches
C = πd²/4
So, the distance, travelled in 1200 revolutions is D = 1200 × C = 1200πd²/4
Substituting d = 16 into D, we have
D = 1200πd²/4
D = 1200π(16)²/4
D = 76800π
D = 241,274.32 inches
The answer is <span>It points in the same direction as it would make a compass point. In a magnetic field, t</span>he direction of the magnetic field at any location is described as the direction in which the north pole of a compass needle points at that location.
Answer: c. displacement
Explanation:
Let's begin by stating clear that motion is the change of position of a body at a certain time. So, during this motion, the body will have a trajectory and a displacement.
In the specific case of the displacement, it is defined as the distance in a straight line between the initial and final position (is a vector magnitude).
Therefore:
Displacement s the the change in position relative to an initial location.
