Answer:

2. F g decreases to 1/9

Explanation:

The formula for calculating the Force of gravity between two masses separated by a distance is expressed as;

F = GMm/d² ... 1

If the distance is tripled, the new force will be;

F1 = GMm/(3d)²

F1 = GMm/9d² ... 2

Divide equation 1 by 2

F/F1 = GMm/d²÷GMm/9d²

F/F1 = GMm/d²×9d²/GMm

F/F1 = 1 * 9

F = 9F1

F1 = 1/9 F

<em>This means that the new force decreases to 1/9</em>

Answer:

0.56 km/s

Explanation:

We will define a single system of units for measurement, for this case meters per second [m/s]. That is, we must convert the rest of units such as centimeters per second and kilometers per second to meters per second.

$560[\frac{cm}{s}]*(\frac{1m}{100cm} )=5.6[m/s]\\0.56[\frac{km}{s}]*(\frac{1000m}{1km} )=560[m/s]$

Therefore the speed of 0.56 [km/s] is the greatest of all
