Answer:
The answer is Temperature.
Net force is basically the force an object has when changing direction, so the answer would be D.
Answer:
The final velocity, , is gd.
Explanation:
The condition here is a free falling object. Thus from the third equation of motion under free fall, we have;
= + 2gs
where is the final velocity of the object, is the initial velocity of the object, g is the gravitational force and s is the height.
Since the object falls from a height of d, then = 0 m/s, and s = d.
So that;
= 0 + 2gd
= 2gd
= 2gd
When the distance is , = 0 m/s.
Then;
= 2g
= g x d
When the object falls through the height , then the final velocity is gd.
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton. meter (N. ... One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m
Ptolemy believed in the theory that the earth was the center of the universe (geocentric) and it is not moving in the center while Copernicus later proposed otherwise, in his heliocentric theory he believed that the sun was the center of the universe but it was not moving. Both theories were influenced by their observation of how the light shade from the sun changes during the day, and also through observation of other celestial bodies whose light intensity changes which made them arrived to the conclusion that they are not equidistant nor stationary with respect to earth.
