Explanation:
A. pure water ....................
Answer:
1.884 meters per second
Explanation:
s = d/t
d = C = 2πr = 2π(6) = 37.68 m
t = 20 s
s = (37.68 m)/(20 s)
s = 1.884 m/s
<u>Answer: The model is described by :</u>
The strength of the field increases as you get closer to Earth, as shown by the smaller spaces between the circles.
Explanation :
According to universal gravitational law, the force acting in the universe between two objects is given by :

It is clear that the gravitational force depends directly on the product of masses and inversely on the square of the distance between them.
The given image shows a model of the gravitational field around Earth. The arrows in the image show the direction of the force. Gravitational field depends on the position of objects.
As we move closer to the earth, the force increases and hence the field increase.
So, the correct option is (D) " The strength of the field increases as you get closer to Earth, as shown by the smaller spaces between the circles ".
Answer:
d.all of the above
Explanation:
The physical feature of the planet Earth affect people's activities in the following manner -
- Choice of Occupation - the process of occupation is completely a land depended process , hence any changes on the physical features of Earth , like the climate , temperature , rain etc , will hinder the occupations process .
- Method of transportation - it is also a Climate dependent process , so any change in climate may obstruct the transportation facility .
- Recreational activities - also depends on the physical feature of the planet Earth .
