How do you read a topographic map?

To read a topographic map you only need to follow the instructions below:

  • Orient your map - Using the compass point the arrow that indicates the north of the map to the same position. Put the compass in a flat place on top of the map for this. Rotate the map until the arrow and the north indication are in the same direction.
  • Find your location on the map - Look around your path to identify landscapes you identify, such as mountains, rivers, or forests. Try to locate these features on the map to find your position on the map.
  • Read the level curves - With the level curves, you will have an idea of ​​the type of terrain that will go through. Remember that the closer the contour lines are, the more inclined the terrain is, and of course the more level the contours are, the flatter it will be. Concentric circles indicate where peaks and hills meet. By convention, the fifth level curve (which indicates multiple values ​​of five) is a bit thicker.
  • Identify the characteristics of the landscape on the map, such as the ridges: Which are the tops of a mountain, so they are the innermost contours of a set of level "rings".

The best way to practice reading a topographic map is to identify the contours of a location that is quite familiar to you. So one of the great secrets to easy learning is to go somewhere we know well and, with a topographic map of the region, identify what each map element wants to identify.

How does the force affect the rocks during collisions? *
Jet001 [13]

In a collision, there is a force on both objects that causes an acceleration of both objects; the forces are equal in magnitude and opposite in direction. For collisions between equal-mass objects, each object experiences the same acceleration.

A 1400 kg car starts from rest on a horizontal road and gains a speed of 61 km/h in 19 s. (a) what is its kinetic energy at the
lana [24]
(a) Let's convert the final speed of the car in m/s:
v_f = 61 km/h = 16.9 m/s
The kinetic energy of the car at t=19 s is
K= \frac{1}{2}mv_f^2= \frac{1}{2}(1400 kg)(16.9 m/s)^2=2.00 \cdot 10^5 J

(b) The average power delivered by the engine of the car during the 19 s is equal to the work done by the engine divided by the time interval:
P= \frac{W}{\Delta t}
But the work done is equal to the increase in kinetic energy of the car, and since its initial kinetic energy is zero (because the car starts from rest), this translates into
P= \frac{K}{\Delta t}= \frac{2.00 \cdot 10^5 J}{19 s}=1.05 \cdot 10^4 W

(c) The instantaneous power is given by
P_i = Fv_f
where F is the force exerted by the engine, equal to F=ma.

So we need to find the acceleration first:
a= \frac{v_f-v_i}{\Delta t}=  \frac{16.9 m/s}{19 s}=0.89 m/s^2
And the problem says this acceleration is constant during the motion, so now we can calculate the instantaneous power at t=19 s:
P_i = Fv=(ma)v=(1400 kg)(0.89 m/s^2)(16.9 m/s)=2.11 \cdot 10^4 W

Hydraulic press is called an instrument for multiplication of force. Why?
Lisa [10]

Answer:

Hydraulic press is called an instrument for multiplication of force. Why? Because it uses Pascal's idea and  principle: F=p*S. If we apply small force to small piston you will generate a pressure. According to Pascal's law pressure is the same everywhere in closed system so the same pressure will act on large piston on the other side too.

Use the drop-down menus to complete the statement.
Nikitich [7]
Classics.

Resistance is equal to relation between voltage and current.

R = \frac{U}{I}

If we express current:

I = \frac{U}{R}

If current is in fact 0 then one of the quantities either voltage or resistance must be equal to zero. Since resistance cannot be equal 0, because that would violate mathematical law that states that division by zero is undefined the only logical conclusion is voltage.

So the answer should be C voltage and B zero.

Hope this helps!
