<span>Thermocline is a layer between
warm water from the ocean’s surface and cool water from below the ocean. In here,
the temperature decreases rapidly from the warmer layer to the colder layer. A thermocline forms due to the heat of the sun
heating the ocean’s surface. Because of the difference in density between warm
and cooler ocean water, cooler ocean water sinks and warmer ocean water floats.
This is caused due to the heat and mass transfer between particles of the
ocean. The answer is letter C. The sun’s radiation does not extend below a
certain depth; therefore, deeper ocean water is colder than surface water.</span>

What is the volume of a right cylinder with a circumference of 25π in and a height of 41.3 in? Explanation: The formula for the volume of a right cylinder is: V = A * h, where A is the area of the base, or πr2. Therefore, the total formula for the volume of the cylinder is: V = πr2h.
Answer:
It is given that power = 5000 W for 120 V and resistance is per 1000 ft of wire. The wire is 750 ft away from 120 V source. We need find the voltage delivered to this load.
Resistance of 750 ft wire, =
Using Ohm's Law:
Voltage delivered to the load,
First speed = 20km/h
Time = 3 hours
Distance = 3×20
<h3> = <u>60 km</u></h3>
Second speed = 30km/h
Time = 4 hours
Distance = 4×30
<h3> = <u>120 km</u></h3>
Total distance = 60+120 = <u>180km</u>
Total time = 3+4 =<u> 7 hours</u>
Average speed = 180/7
<h3> = <u>25.71</u><u> </u><u>km</u><u>/</u><u>h</u></h3>

Answer:
Force,F =
Explanation:
Given that,
Charge 1,
Charge 2,
Negative charge is 0.002 m north of a positive charge, distance between charges, d = 0.002 m.
Let is the magnitude of electrical force applied by q₁ on q₂. We know that the electrical force is given by the formula as follows :
So, the electrical force applied by q₁ on q₂ is towards north.
