<h2>Without being able to look into the Earth, a scientist would not be able to determine if this region has karst topography, is a false statement</h2>

Explanation:

  • Karst topography can be observed by looking into the earth’s external surface structures like barren rocky grounds, caves, underground rivers, sinkholes and other karst landscapes.
  • Karst topography results due to erosion of limestone by the excavation of underground water. When rainwater erodes the soft rocks like limestone it begins to slowly dissolve in water.
  • Over repeated erosion, only the rocky cliffs remain on the surface. When an underground river emerges from sinkholes in a karst landscape, the rocky remains form caves.
  • So by studying these external surfaces itself, the scientist can determine if a region has karst topography

KATRIN_1 [288]

Answer:

B = 62.9 N

Explanation:

This is an exercise on Archimedes' principle, where the thrust force equals the weight of the  liquid

         B = ρ g V

write the equilibrium equation

         T + B -W = 0

         B = W- T               (1)

use the density to write the weight

         ρ = m / V

        m = ρ V

         W = ρ g V

substitute in  1

         B = m g -T

         B = \rho_{body} g V - T

To finish the calculation, the density of the material must be known, suppose it is steel  \rho_{body} = 7850 kg / m³

calculate

         B = 7850 9.8 1.20 10⁻³ - 29.4

          B = 92.3 - 29.4

          B = 62.9 N

A youngster having a mass of 50.0 kg steps off a 1.00 m high platform. If she keeps her legs fairly rigid and comes to rest in 1
attashe74 [19]

The average act on her during the deceleration is 4.47 meters per second.                                                                

<u>Explanation</u>:

<u>Given</u>:

youngster mass m = 50.0 kg

She steps off a 1.00 m high platform that is s = 1 meter

She comes to rest in the 10-meter second

<u>To Find</u>:

The average force and momentum

<u>Formulas</u>:

p = m * v

F * Δ t = Δ p

vf^2= vi^2+2as

<u>Solution</u>:

a = 9.8 m/s

vi = 0

vf^2= 0+2(9.8)(1)

vf^2 = 19.6

vf = 4.47 m/s .

Therefore the average force is 4.47 m/s.
