B.) They have no effect on air temperature over land on the coast.
Explanation:
The statement that ocean surface currents do not have any effect on air temperature over land on the coast is very incorrect.
In fact, ocean surface currents shapes the coast a whole lot.
- There is a constant interaction between the ocean surface current and the air masses on land.
- They interact by simple convection through which heat is transferred from one point to the other.
- During the day, air masses moves from the land to the ocean because air around the coast are hotter and less dense.
- They are quickly replaced by colder and less denser air from the ocean.
- At night the reverse is the case.

<span>C. free electrons. Plasma is made up of atoms. The atoms have had some or all of the electrons stripped away. The nuclei are positively charged and are called ions. The ions roam freely. Gases are made up of both molecules and atoms.</span>
Answer:
Flooding of roads near the coast
Explanation:
-Storms surges have the potential to harm lives and property via storm surge, heavy rain or snow causing flooding or road impassibility, lightning, wildfires, and vertical wind shear.
-The significantly high amounts of rainfall during storms leads to flooding of coastal regions , roads included thus rendering them impassable.
<span>If the swimmer is swimming perpendicular to the current, it will take her 66m / 0.42 m/s = 157.14 seconds to cross the river. At the same time, the current will be taking her downstream at a rate of 0.32 m/s. So, when she reaches the opposite bank, her total downstream distance traveled will have been 0.32*157.14 = 50.28 meters.</span>
Use the formula for kinetic energy.
KE=1/2mv^2
KE=1/2*(82kg)*(2.8m/s)^2
KE=321.4 J
The answer is C
