What effect do increasing amounts of greenhouse gases have on earth and the organisms that live here?

Physics

pickupchik [31]3 years ago

Answer and Explanation:

The increasing amounts of greenhouse gases causes climate change and global warming, sea level rises and oceans become warmer.

When prolonged into the future and no actions are being taken; drastic droughts will happen which threatens agricultural in an extreme manner, wildlife living in the forests will be pressurized, and animals/organisms living in the ocean will be affected too due to rising temperature causing the reduced Oxygen effects.

The examples include: the melting of Arctic ice endangering the polar bears, fishes and aquatic marines will die at part of the oceans which has higher temperature (lack of oxygen), poorer regions will have adverse impacts on the human being due to agriculture deterioration and lack of proper system and social readiness to adapt to climate change.

To fight climate change, we must reduce carbon pollution (burning of coals which releases large carbon dioxide/monoxide etc.) through setting up of policies by multinational companies, greener business to reduce emissions, and help people to adapt to climate change or at least educate people about climate change.

Answer:

An increase in the greenhouse gases implies an increase in the average temperature of the atmosphere which might lead to extreme weather conditions, rise of sea levels etc It will affects animal food sources and habitats.  

Explanation:

Greenhouse gases covers the earth like a shield or covering. Human activities for example industrialization, deforestation, burning of coal, natural gases and fossil fuels etc adds extra layers of thickness to the already existing greenhouse gases thereby making it impenetrable by heat. This trapped heat is what is responsible for the increased average global temperature.

The effects are numerous and can be detrimental to say the least. When there is an increase in temperature, algae(water plant) which acts as a direct source of food for small fishes dies off which could lead to extinction of smaller fish species which is a direct food source for bigger fishes and the cycle continues which translates into reduced food supply for animals(including man).

Sunshine Corporation is expected to pay a dividend of $1.50 in the upcoming year. Dividends are expected to grow at the rate of
grigory [225]

Answer:

$25

Explanation:

The computation of the intrinsic value of the stock is shown below:

As we know that

Intrinsic value or Price = Dividend ÷ (Cost of equity - growth rate)

where,

Cost of equity or ke  is

= Risk free rate of return  + beta × (Market rate of return - risk free rate of return)

= 6% + 0.75 × (14% - 6%)

= 12 %

So the intrinsic value is

= $1.50 ÷ (12% - 6%)

= $25

The inductor in a radio receiver carries a current of amplitude 200 mA when a voltage of amplitude 2.4 V is across it at a frequ
zzz [600]

Answer:

The value of the inductance is 1.364 mH.

Explanation:

Given;

amplitude current, I₀ = 200 mA = 0.2 A

amplitude voltage, V₀ = 2.4 V

frequency of the wave, f = 1400 Hz

The inductive reactance is calculated;

X_l = \frac{V_o}{I_o} \\\\X_l = \frac{2.4}{0.2} \\\\X_l =12 \ ohms

The inductive reactance is calculated as;

X_l = \omega L\\\\X_l = 2\pi fL\\\\L = \frac{X_l}{2 \pi f}

where;

L is the inductance

L = \frac{12}{2 \pi \times \ 1400} \\\\L = 1.364 \times \ 10^{-3} \ H\\\\L = 1.364 \ mH

Therefore, the value of the inductance is 1.364 mH.

If someone ways 600 newtons and the shoes have an area of 300cm squared, what pressure does he exert on the ground?
lukranit [14]
Pressure = Force / Area

Put your data in front of yourself.

Force = 600 Newtons
Area = 300 cm^2

Firstly you need to convert the area into m^2 and you do this by diving 300 with 10000.

Now you use the formula:-
Pressure = 600/ 0.03
Which comes out to be 20,000 Pa.

Hope this helps!

Before giving an injection, a nurse dabs some alcohol onto the patient`s arm. This makes the patient`s skin feels cold. Explain
mezya [45]

Answer:

Before giving an injection, a nurse dabs some alcohol onto the patient`s arm. This makes the patient`s skin feels cold. Explain Why ?

<em> Evaporative cooling makes this to be possible</em>

Explanation:

The concept

For a liquid to evaporate, there must be a breakdown of the bond between the molecules of the liquid. These bonds are broken when the molecules gain heat energy. So basically evaporation occurs when the molecules of the substance gain energy in form of heat.

Our Scenario

Just like the way our body excretes sweat on a sunny day, alcohol takes energy from the skin to evaporate. The bond holding the molecules of alcohol breaks faster due to its low boiling point and this account why it evaporates faster. The sudden evaporation of alcohol when dabbed on the skin results in quick utilization of heat energy making the skin feel cold for some time.

The utilization of heat energy from the skin results in evaporation cooling which makes the skin feel colder.

A piston-cylinder device initially contains 0.3 kg of nitrogen gas at 160 kPa and 140oC. The nitrogen is now expanded isothermal
irakobra [83]

Answer:

<h2>Work done by the gas is given as</h2><h2>W = 1.72 \times 10^4 J</h2>

Explanation:

As we know that the process is isothermal so here work done is given as

W = nRTln(\frac{P_1}{P_2})

here we know that

n = \frac{w}{M}

n = \frac{300}{28} = 10.7 moles

now we have

W = 10.7 (8.31)(273 + 140) ln(\frac{160}{100})

so we have

W = 1.72 \times 10^4 J
