Marine plants, such as algae, use CO2 to make energy. Ocean fertilization is the introduction into oceans of nutrients that encourage the growth of these plants. How can this technique affect the pH in oceans that already have higher than normal CO2 readings?

Answer:

Explanation:

Geoengineering schemes involving ocean fertilization to affect climate have a low chance of success, according to the first summary for policymakers on the issue.

Failure to tackle rising greenhouse gas emissions effectively has led to intensifying debate on geoengineering – deliberate large-scale schemes to slow the rate at which Earth is heating up. The public debate often mixes opinion with fact so scientists have now released the first summary for policymakers on ocean fertilization, one of the earliest geoengineering proposals. The authors report that the chances of success of using ocean fertilization to deal with climate change is low.

Ocean fertilization involves adding iron or other nutrients to the surface of the ocean to trigger growth of microscopic marine plants.  These plants use dissolved carbon dioxide to grow, which led to the idea that deliberate fertilization of the ocean on a large scale would remove carbon dioxide from the atmosphere.

Lead author of the report Professor Doug Wallace from the Leibniz-Institut für Meereswissenschaften (IFM-GEOMAR) says: “The published findings suggest that even very large-scale fertilization would remove only modest amounts of carbon dioxide from the atmosphere over 100 years”.

For two decades, marine scientists have been carrying out a series of small-scale fertilization experiments to understand how ocean ecosystems respond to environmental change. However the experiments were not designed to address issues relating to geoengineering. Proposals to scale up this approach to slow climate warming or be included within emissions trading schemes to generate carbon credits have stimulated intense debate and criticism amongst scientists and the public.

Lapatulllka [165]

Answer:

Possibly shape.

Explanation:

Because it is ripped in half. As you guys and the questioner can see that there is a wiggly strip down the middle. That also cause of a shape change.

I really hope my answer is right ^_^

iragen [17]

Answer:

it have Potential energy

Explanation:

given data

Drag the pendulum to an angle 30∘

to find out

what form of energy does it have

solution

we know that pendulum start no kinetic energy when it release from any rest position then in starting it have potential energy only so that when pendulum is angle 30∘ at some height from ground so when it start it have potential energy same as in starting.

we know that the total energy is always conserve  

so it have potential energy

Basile [38]

a) 120 s

b) v = 0.052R [m/s]

Explanation:

a)

The period of a revolution in a simple harmonic motion is the time taken for the object in motion to complete one cycle (in this case, the time taken to complete one revolution).

The graph of the problem is missing, find it in attachment.

To find the period of revolution of the book, we have to find the time between two consecutive points of the graph that have exactly the same shape, which correspond to two points in which the book is located at the same position.

The first point we take is t = 0, when the position of the book is x = 0.

Then, the next point with same shape is at t = 120 s, where the book returns at x = 0 m.

Therefore, the period is

T = 120 s - 0 s = 120 s

b)

The tangential speed of the book is given by the ratio between the distance covered during one revolution, which is the perimeter of the wheel, and the time taken, which is the period.

The perimeter of the wheel is:

L=2\pi R

where R is the radius of the wheel.

The period of revolution is:

T=120 s

Therefore, the tangential speed of the book is:

v=\frac{L}{T}=\frac{2\pi R}{120}=0.052R

Naily [24]

Answer:

This type of heat transfer occurs inside materials, typically solid materials. The heat from the fire is passed from molecule to molecule along the length of the material. The fire will generally follow the heat or sometimes the heat from conduction may cause a new fire to ignite elsewhere. The conduction is happening in the walls of the fireplace

LuckyWell [14K]

Answer:

C. 2 N forwards

Explanation:

Net Force in y direction = 0 since the lift force and gravity cancel out. Net force in x direction = 6 N forward - 4 N backwards = 2 N forwards.
