The image shows a model of the gravitational field around Earth. An illustration of the earth with concentric circles going out away from the earth and radial lines going out away from the earth. On each radial line is an arrow pointing toward earth.
Which best describes the model?

The field exerts an attractive force only outside of the ring of arrows that point toward Earth’s surface.
The field exerts an attractive force only within the ring of arrows that point toward Earth’s surface.
The strength of the field increases as you get farther from Earth, as shown by the larger spaces between the circles.
The strength of the field increases as you get closer to Earth, as shown by the smaller spaces between the circles.

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
