Answer:
They diverge on refraction
Explanation:
When parallel light rays strike a concave lens, they will diverge that is they spread out .
Concave lens is also known as diverging lens, which means that when parallel rays of light strike on it, the lens spreads out the light rays ( that is it diverges the rays of light) that are refracted through it.
At the middle of concave lens is thinner.
When light is passes through the lens they diverge it or spread out.
The concave lens causes light rays to bend away or diverge from its axis since the concave lens is a diverging lens.
PART A)
Here we know that
potential difference across the wire is

resistance of wire is

now by ohm's law



Part b)
Power rating is defined as rate of electrical energy
it is defined as

now we have


Answer:
Compression- pushing together
Refraction- pulling apart
Wavelength- the length of the wave

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:
Because in order for work to be done on an object, the object must be moving. Why isn't work being done on a barbell when a weight lifter is holding the barbell over his head? Work is maximized when force is applied in the same direction that the object is moving. ... In order to do work faster, more_is required.
