Explanation:

The movement of deep ocean currents is mainly caused by:?

Answers

The relationship between the density of ocean water and the formation of deep currents. Difference in the tempature and salinity and the resulting differences in density cause variations int he movement of deep currents. For example, the deepest current , The Antarctic Bottom Water, is denser than the North Atlantic Deep Water. Both currents spread across the ocean floor as they flow toward eachother. Because less dense water always flows on top of denser water, The north Atlantic Deep Water flows on top of the Atlantic Bottom Water when the currents meet.

What is the acceleration due to gravity of a feather? Is it smaller than that of an iron ball?

Answers

A hammer and a feather will fall with the same constant acceleration if air resistance is considered negligible. This is a general characteristic of gravity not unique to Earth, as astronaut David R. Scott demonstrated on the Moon in 1971, where the acceleration due to gravity is only 1.67 m/s2.

Final answer:

The acceleration due to gravity is the same for all objects near the surface of the Earth, regardless of their mass. The effect of air resistance may make it appear that the acceleration of a feather is smaller than that of an iron ball.

Explanation:

Acceleration due to gravity refers to the rate at which an object falls toward the Earth under the influence of gravity. The value of acceleration due to gravity varies depending on the location and mass of the object.

In general, the acceleration due to gravity is the same for all objects near the surface of the Earth, regardless of their mass. This means that the acceleration due to gravity of a feather is the same as that of an iron ball. However, due to the difference in air resistance, a feather will experience a much smaller net force compared to an iron ball, which may give the illusion of a slower acceleration.

Therefore, the acceleration due to gravity of a feather is not smaller than that of an iron ball, but the effect of air resistance makes it appear so.
