<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.
If we assume that the acceleration is constant, we can use on the kinematic equations:
Vf = Vi + a*t = 15 + 3*4 = 27 m/s
Women have lower centers of gravity, and lower centers of gravity provide more stability.
The correct option is C.
<h3>What is centre of gravity with example?</h3>
The location in a system or body where the weight is equally distributed and all sides are in balance is known as the center of gravity. The middle of a seesaw is an illustration of a center of gravity. the center of mass of an object in a gravitational field that is uniform.
<h3>How can you improve your center of gravity?</h3>
Training your legs and lower body is essential since they contain the biggest muscles in your body, as any competent bodybuilder or strength athlete will tell you. Exercises like squats, lunges, and calf raises should be a regular part of your workout routine if you want to reduce your center of gravity.

Answer:
Balancing of forces,
In the X-direction:
-Tcos4.5^o +Tcos4.5^o=0
In the Y-direction:
Tsin4.5^o +Tsin4.5^o-m*g=0
2Tsin4.5^o=15*9.81
T=(15*9.81)/(2sin4.5^o)
=937.75 N
Therefore, tension in the rope is 937.75 N.
