Please help fast!! ASAP The amount of energy received by a surface depends on the angle of incidence of the incoming light. The angle of
incidence is the angle that a ray of light makes with an imaginary perpendicular line (a normal) extending from the
surface. In this activity, you will answers question based on this and other information
Part A
When we talk about energy from light that a surface receives, we use the word irradiance (E). Irradiance measures the
amount of energy per second (P) that arrives on a surface per unit area (A). As an equation, this idea can be expressed in
this way: E = P/A.
As the angle of the light source moves from 0° to 45°, the illuminated area (A) increases. You can see this increase in the
image. However, although the illuminated area increases, the energy per second (P) from the light is constant. What effect
will an increase in the angle of light, and therefore illuminated area (A), have on irradiance (E)?

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
