By a factor of 32 = 9. In general, surface area (for any two similar objects) is proportional to the square of any linear measurement.
Assuming you are already sure that the two objects are, indeed, similar: You measure corresponding lengths of the two objects, and divide.You measure the lengths of a pair of corresponding sides. The scale factor is the ratio of the two measures.
One of the factors that determine whether water infiltrates is the nature of the surface. Another factor that determines is the elevation of the surface or its shape.
The amount of traction its tires have on the road surface over which they are rolling.
The amount of traction its tires have on the road surface over which they are rolling.
The mass and distance (weight and height) determine the potential energy. A third factor can be the relative motion of the objects, which does not change the potential but may determine its effect.
None of these matter. With no air resistance, they all hit the ground at the same time.
Four factors that determine the location, size, shape, and direction of a gyre are wind, gravity, Coriolis Effect, and topography.
It is 21/23.
It's initial mass. Other smaller factor are also relevant, like the amount of metallicity and the proximity of other large objects.
the vehicle should be similar to other vehicles having routine access to the target area
Divide the factor into the number. If the answer is a whole number, the factor is a factor.
