The image shows a model of the gravitational field around 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.

the answer is D "The strength of the field increases as you get closer to Earth, as shown by the smaller spaces between the circles"

Explanation:

The model is described by :

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 ".

we need to know the time interval during which the force acts. impulse of force = momentum change

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s.
