The alteration of a rivers flow and sediment transport down stream of a dam often causes the greatest sustained environmental impacts. Life in and around a river evolves and is conditioned on the timing and quantities of river flow

Answer:

Some of the effects of the dam on the water cycle in that region are as follows-

1) The river water carries various type of nutrients which are blocked at the reservoir. as a result of which the number of algae increases that are toxic in nature. This degrades the quality of the water and makes it unfit for drinking.

2) The rate of evaporation is very high when the water is trapped in the dams providing a huge surface area. As a result of which most of the water gets evaporated and is stored in the atmosphere.

3) The deepening of the river bed also occurs, which extends for a long distance below the reservoir dam. This causes the groundwater level to drop down and affects the flood plain areas and the vegetation-covered regions.

A family is skating at an ice rink. The 58.2 kg mother is holding the

MariettaO [177]

Answer:

When I got this question I had to draw it out so if you have to do that, draw 3 stick figures holding hands, one representing the mother, father, and daughter. Then you write their weights on top of them and then draw an arrow pointing from the father to the mother.

Explanation:

use this formula :

$a_{y}$ = $\frac{Fdadshandy}{msys}$

then you fill it in :

$a_{y}$ = $\frac{100N}{35.5kg+58.2kg}$

$a_{y}$ = $\frac{100N}{93.7kg}$

$a_{y}$ = $1.0672$ $m/s^{2}$

then you multiply that with the daughters weight :

$T_{2} x= m_{2} a_{y}$

$T_{2} x = 35.5kg (1.0672 m/s^{2})$

$T_{2} x = 37.89N$

and that's the answer :) : 37.89N

when an element tends to lose its valence electrons in chemical reactions , does it behave more like a metal or nonmetal

Juli2301 [7.4K]

It behaves more like a metal

Explanation:

When an element tends to lose its valence electrons in chemical reactions, they behave more like a metal.

Metals are electropositive.

Electropositivity or metallicity is the a measure of the tendency of atoms of an element to lose electrons.

This is closely related to ionization energy and the electronegativity of the element.

The lower the ionization energy of an element, the more electropositive or metallic the element is .

Metals are usually large size and prefers to be in reactions where they can easily lose their valence electrons.

When most metals lose their valence electrons, they attain stability.

Non-metals are electronegative. They prefer to gain electrons.
