When the water molecules of the ocean become heated, they expand. ... Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity. To relate this to ocean currents, the higher the salinity of ocean water, the more dense it becomes. THIS IS NOT FROM MY OWN WORDS, IF YOURE TYPING THIS DOWN PLEASE REPHRASE IT A BIT!! :)
From the computation, the magnitude of the drag force when the skydiver reached terminal speed is 784 Newtons.
<h3>How to calculate the magnitude</h3>
From the complete information, the skydiver has a mass of 80kg and jumps off a plane. The free-fall acceleration is also given as 9.80m/s².
Therefore, the weight of the skydiver will be:
W = mass × acceleration
W = 80 × 9.80
W = 784N
In conclusion, the magnitude of the drag force due to air resistance is 784N.

Answer:
In Piaget's developmental theory, several explanations were used to describe the growth of children. For the child who expects his mother to tell him who is in the picture although she is not there, the child is experiencing;
Object Permanence
Object permanence refers to a child's ability to know that something continues to exist even though it cannot be seen or heard at the time.
In the child's case above, even though his mother is in another room outside of his view, he still recognizes that his mother is there and calls out to her.
Object permanence has been developed in this child.
