Answer:

The contour lines are the third dimension, showing the elevation of an area

Explanation:

Topographic maps are those that shows the topography of a particular area, type of relief and the location of hills and plains. They are provided with the north direction and the index that helps in a better understanding of the maps. They are commonly used by geologists and geographers.

The third dimension of the map i.e the height of the surface features is shown in terms of contour lines. Contour lines are the lines of equal elevations. They are shown by a number that depicts the height at that point from the mean sea level. The high mountains, valleys, and basins are easily identified from these maps.

An object or any location can be represented on a two-dimensional surface like a paper or computer screen. This representation is known as map. Most maps do not take into account the elevation of the object or the location they representing. On the other hand, Topographic maps use contour lines to represent the third dimension and to show elevation change on or below the surface of the earth.

faust18 [17]

Answer:

a)  r = 6122 m and b) v = 32.5 m / s

Explanation:

a) The train in the curve is subject to centripetal acceleration

         a = v2 / r

Where v is The speed and r the radius of the curve

They indicate that the maximum acceleration of the person is 0.060g,

        a = 0.060 g

        a = 0.060 9.8

        a = 0.588 m /s²

Let's calculate the radius

        v = 216 km / h (1000m / 1km) (1 h / 3600 s =

        v = 60 m / s

        r = v² / a

        r = 60² /0.588

        r = 6122 m

b) Let's calculate the speed, for a radius curve 1.80 km = 1800 m

        v = √a r

        v = √( 0.588 1800)

        v = 32.5 m / s

Mars2501 [29]

Answer:

2.72*10-3 Joules

Explanation:

From Newton's second law of motion

F=ma

\tau=I*\alpha

given

\tau= 0.11Nm\\\\I=0.034kgm^2\\\\t= 8s\\\\\alpha=?

\alpha =0.11/0.034\\\\\alpha=3.23 rad/s^2

the angular velocity is

\omega = \alpha/t\\\\\omega =3.23/8\\\\\omega =0.4 rad/s

KE= 1/2*I* \omega^2

KE=1/2*0.034*0.4^2\\\\KE=1/2*0.034*0.16\\\\KE=0.00272\\\\KE=2.72*10^-3J

What is the wavelength of a 2.50-kilohertz sound
Alexxx [7]
The formula v=fλ can be used here.

326=2500*λ

Note the 2500 as 2.5kHz is 2.5 thousand Hz.

λ = 326/2500
= 0.1304m = 0.130m
