<u>Answer:</u>
<h2>
Cold, Salty water.</h2>
<u>Explanation:</u>
The cold, salty ocean water is denser than the warmer water. Because of higher density, cold water sinks into the bottom of the ocean while warm water remains at the surface.
The sinking of the cold water at depth moving away from the surface generates deepwater currents by a process called upwelling. These deepwater currents bring the nutrient-rich water at the surface providing food and nutrients to marine life.
Answer:
Explanation:
Mass of moon = m
Mass of planet =M
We know that gravitational force given as
Given that force is zero so
F=F'
It is combination of two ideas that could help explain about electric charges of an atom.

Answer: acceleration a = 25m/s^2
Explanation:
Given that:
The plane travels with constant acceleration
x1 = 241.22 m at t1 = 3.70 s
x2 = 297.60 m at t2 = 4.20 s
x3 = 360.23 m at t3 = 4.70 s.
We need to calculate the velocity in the two time intervals.
Interval 1:
Average Velocity v1 = ∆x/∆t = (x2 - x1)/(t2-t1)
v1 = (297.60-241.22)/(4.20-3.70) = 112.76m/s
Interval 2:
Average Velocity v2 = ∆x/∆t = (x3-x2)/(t3-t2)
v2 = (360.23-297.60)/(4.70-4.20)
v2 = 125.26m/s
Acceleration:
Acceleration a = ∆v/∆t
∆v = v2-v1 = 125.26m/s-112.76m/s = 12.5m/s
∆t = change in average time of the two intervals = (t3-t1)/2 = (4.70-3.70)/2 = 0.5s
a = 12.5/0.5 = 25m/s^2
