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
Answer:
hope this helps
Explanation:
Coating surfaces with oil reduce friction between the surfaces because it is like when lubricating a machine, it makes it run or it makes it become smoother.
Choice-'b' says the formula for kinetic energy in words.
KE = (1/2) · (M) · (S²)
The slope of the illustrated graph would give us the velocity of the object whose motion is plotted in the graph.
<h3>What is velocity?</h3>
Velocity refers to the rate of movement of objects along a particular line. In other words, the velocity of an object is the speed of the object in a specific direction relative to time.
Also, velocity = displacement/time.
In the graph, the slope is given by: Δy/Δx = displacement/time = velocity.
