Answer:

Some of the effects of a dam on the environment includes;

1) Increase in the amount of the greenhouse gases

2) Removal of the natural wetland and ocean carbon sinks

3) Disruption of the sources of nutrients in the ecosystem

4) Destruction of habitats

5) Raising of the sea levels and waste waters

6) Displace villages and communities

7) Dams have a potential to create flood risk

8) Dams lead to increased water loss due to evaporation and transpiration

9) Dams causes earthquakes

Explanation:

Dams are a source of renewable energy and are a means to prevent floods, however, dams can also have detrimental impact on the climate and the environment.

Answer:

$v = 10.89\ m/s$

Explanation:

given,

radius of loop = 12.1 m

to find the minimum speed transverse by the rider to not to fall out upside down

centripetal force = $\dfrac{mv^2}{r}$

gravitational force = m g

computing both the equation]

$mg = \dfrac{mv^2}{r}$

$v = \sqrt{rg}$

$v = \sqrt{12.1 \times 9.8}$

$v = \sqrt{118.58}$

$v = 10.89\ m/s$

Waves of wavelength 24 cm and amplitude 3.0 em are used to create a standing wave. The distance from one node tothe next in the

NikAS [45]

Answer:

D. 12 cm

Explanation:

A node is a point on a standing wave that does not vibrate.

The nodes of a standing wave are shown in the following sketch.

The red dots are the nodes of the standing wave.

It is observed that the distance between two adjacent nodes is half the wavelength of the wave.

Therefore, if the wavelength of the wave is 24 cm, then the distance from one node to the net must be 24 / 2 = 12 cm.

Hence, choice D is the correct answer.

the temperature of monoatomic gas was increased from t1=27c to t2=177c. by how many times the internal energy of the gas increas

Romashka [77]

The internal energy increases 1.5 times

Explanation:

the internal energy of a mono atomic gas is given by E= 3/2kT

T1= 27⁰C= 27+273=300 K

T2=177⁰C= 177+273=450 K

E1= 3/2 k (300)

E2=3/2 k (450)

so E2/E1=[3/2 k (450)][3/2 k (300)]

E2/E1=450/300

E2= 1.5 E1

so the internal energy increases by a factor of 1.5
