Answer:
The distance from the Sun to Neptune is 29,41 AU.
Explanation:
We know, from the sentence, that the orbit of Neptune has an average diameter around 8.80*10⁹km.
Now, we can calculate the radius of this orbit, which is equivalent to the distance from thsi planet to the Sun. Let's recall tha the radius is the half of the diameter.
Ok, we know that 1.496*10¹¹m is an AU, therefore we have:
Finally, the distance R is 29,41 AU.
I hope it helps you! :)
The vertical forces present in a boxcars being pulled by a train are weight and pull of air on the boxcars.
The forces exerted on an object can be resolved into <em>horizontal</em> and <em>vertical components.</em>
<em />
The horizontal components of the forces on an object being pulled include the following;
- The frictional force on the object; which tends to reduce the motion,
- force dragging the object forward
- if the object is inclined to an angle, the horizontal component of the weight
This horizontal force is written as;
The vertical component of the force on the object include the following;
- the weight of the object acting downwards
- the pull of air on the object acting upwards
The vertical force on the object is written as;
Thus, the vertical forces present in a boxcars being pulled by a train are weight and pull of air on the boxcars.
