Answers
0.045=n*1.6*10^-19
divide both sides by 1.6
0.028125=n*10^-19
divide both sides by 10^-19
0.028125*10^19=n
2.8125*10^17=n

Answers
Answer: Refraction.
Explanation: The lenses are used to "transmit" the light that hits the lens in a certain way.
The phenomena in which the light penetrates a medium (where the medium, in this case, is the lens) is called diffraction.
Reflection would be more related to mirrors, difraction is the change of the velocity of the light waves when they are in different mediums, and interference refers to the interaction between two coherent waves (it can be destructive interference, where the waves cancel each other, or constructive interference, where the waves add to each other)

The force of 27 N acts horizontally, so its horizontal component is 27 N.
The force of 81 N acting at an angle needs to be resolved into its horizontal and vertical components. The horizontal component is given by 81 N * cosθ, where θ is the angle between the force and the horizontal direction. Since the angle is not specified in the question, we cannot determine the exact value of the horizontal component without that information.
Once we have the horizontal components of the forces, we can calculate the net horizontal force acting on the block by summing up all the horizontal components. In this case, the only horizontal force is the force of 27 N, so the net horizontal force is 27 N.
Using Newton's second law, F = ma, where F is the net force and m is the mass of the block, we can solve for the acceleration.
a = F / m
a = 27 N / 2.2 kg
a ≈ 12.27 m/s^2
Therefore, the magnitude of the resulting acceleration of the block is approximately 12.27 m/s^2.

Final answer:
Solar flares can be excluded from a list of interactions among Earth's spheres because they are not directly related to interactions among the geosphere, hydrosphere, atmosphere, and biosphere.
Explanation:
The event that can be excluded from a list of interactions among Earth's spheres is A solar flares. Solar flares are not directly related to interactions among Earth's spheres, which include the geosphere, hydrosphere, atmosphere, and biosphere.
On the other hand, volcanic eruptions, fracking for natural gas, and hurricanes are all examples of interactions among Earth's spheres. Volcanic eruptions involve the release of gases and materials from the geosphere into the atmosphere. Fracking for natural gas involves extracting resources from the geosphere and potentially impacting the hydrosphere. Hurricanes involve interactions between the atmosphere and the hydrosphere, resulting in powerful storms.
Therefore, the correct answer is A solar flares.
