By the force of universal attraction

Explanation:

The gravitational attraction of a large body (planet) on an object on its surface can be calculated with the same equation of universal gravitation

F = G m1 m2 / r²

Where G is the Universal gravitation costing 6.67 10⁻¹¹ N m²/Kg², m1 the mass of the planet, r the distance that we can take equal to the average radius of the planet and m2 the mass of the object that we can leave out, what remains of the equation is called acceleration of the planet's gravity, let's write the equation explicitly

g = G m1 / r²

We look for the data of the two planets, for the earth, they are 5.98 10²⁴ kg and 6.37 10⁶ m for their mass and radius, respectively; for Uranus we have 8.68 10²⁵ Kg and 2.54 10⁷ m; Let's calculate the values of the acceleration of gravity for each

Earth

g = 6.67 10 -11 5.98 10 24 / (6.37 10 6) 2

g = 9.87 m / s

Uranus

g2 = 6.67 10 -11 8.68 10 25 / (2.54 10 7) 2

g2 = 8.97 m / s

We can see that the gravity of Uranus is less than the gravity of the earth.

This could be intuited since the force of gravity depends on the inverse of the square of the distance and only proportionally with the mass.

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
