A model is considered to scale if its relative proportions are equal to that of the object its modeling. If a building is twice

as tall as it is wide, then a scale model of the building will also be twice as tall as it is wide regardless of how big the model is relative to the real building.
The picture below is of a relief globe. The height of objects (above or below sea level) on a relief globe use a different scale than their widths and lengths.

Without knowing the scale used for the heights of objects, what could be figured out accurately using this relief globe?

A. Where the highest and lowest places on earth are
B. The kinds of terrain on different parts of the earth
C. How high above sea level a certain mountain is
D. How much later the sun sets on top of a mountain than in a valley

Answer:

The correct option is B.

B. The kinds of terrains on different paths of the earth.

Explanation:

Looking at relief globe, we can clearly see the heights and types different areas of the world. We can not accurately determine the height of any area because we do not know the scale factor. We certainly cannot determine the highest or lowest point on the earth because it is impossible to calculate just from looking at the globs. We cannot find the height of a mountain above sea level or any other height measurement. It is also no where related to time of sun rising and setting in a particular area.

A spool whose inner core has a radius of 1.00 cm and whose end caps have a radius of 1.50 cm has a string tightly wound around t
White raven [17]

Answer:

v₁ = 37.5 cm / s

Explanation:

For this exercise we can use that angular and linear velocity are related

        v = w r

in the case of the spool the angular velocity for the whole system is constant,

They indicate the linear velocity v₀ = 25.0 cm / s for a radius of r₀ = 1.00 cm,

         w = v₀ /r₀

for the outside of the spool r₁ = 1.5 cm

         w = v₁ / r₁1

since the angular velocity is the same we set the two expressions equal

        \frac{v_o}{r_o} = \frac{v_1}{r_1}

        v1 = \frac{r_1}{r_o} \ \ v_o

let's calculate

       v₁ = \frac{1.50}{1.00} \ \ 25.0

       v₁ = 37.5 cm / s

A boy starts from point A and walks 3 meters toward the north, then turns around and walks 6 meters toward the south.
docker41 [41]

Answer:

Total distance traveled = 9 m

Explanation:

Given:

Distance travel towards north = 3 meter

Distance travel towards south = 6 meter

Find:

Total distance traveled

Computation:

Total distance traveled = Sum of total distance

Total distance traveled = Distance travel towards north + Distance travel towards south

Total distance traveled = 3 m + 6 m

Total distance traveled = 9 m
