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).

The terminal velocity is not dependent on which one of the following properties? the drag coefficient 1 the force of gravity 2 c

ahrayia [7]

<h2>Answer: the falling time</h2>

Explanation:

When a body or object falls, basically two forces act on it:

1. The force of air friction, also called<em> </em><u><em>"drag force"</em></u> $D$ :

$D={C}_{d}\frac{\rho V^{2} }{2}A$ (1)

Where:

$C_ {d}$ is the drag coefficient

$\rho$ is the density of the fluid (air for example)

$V$ is the velocity

$A$ is the transversal area of the object

So, this force is proportional to the transversal area of the falling element and to the square of the velocity.

2. Its <u>weight </u>due to the gravity force $W$ :

$W=m.g$

(2)

Where:

$m$ is the mass of the object

$g$ is the acceleration due gravity

So, at the moment <u>when the drag force equals the gravity force, the object will have its terminal velocity:</u>

$D=W$ (3)

${C}_{d}\frac{\rho V^{2} }{2}A=m.g$ (4)

$V=\sqrt{\frac{2m.g}{\rho A{C}_{d}}}$ (5) This is the terminal velocity

As we can see, there is no "falling time" in this equation.

Therefore, the terminal velocity is not dependent on the falling time.

A 12 oz can of soda is left in a car on a hot day. In the morning the soda temperature was 60oF with a gauge pressure of 40 psi.

Neko [114]

In this case, volume of the can remains constant. The relationship between pressure and temperature at constant volume is given by:

P/T = Constant

Then
$\frac{ P_{1} }{ T_{1} } = \frac{ P_{2} }{ T_{2} }$

Where
P1 = 40 psi
P2 = ?
T1 = 60°F ≈ 289 K
T2 = 90°F ≈ 305 K (note, 363 K is not right)

Substituting;
$P_{2} = \frac{ P_{1} T_{2} }{ T_{1} } = \frac{40*305}{289} =42.21 psi$

100 Points!!!

Kaylis [27]

(1) The image of an object placed further from the lens than the focal point will be upside down and smaller than the object.

(2) When light rays reflect, they bounce back.

(3) Images formed by a concave lens will look magnified.

(4) When light rays enter a different medium, they bend.

<h3>1.0 Object placed further from the lens than the focal point</h3>

The image of an object placed further from the lens than the focal point will be diminished and inverted.

Thus, the correct answer will be "upside down and smaller than the object".

<h3>2.0 What is reflection of light?</h3>

The ability of light to bounce back when it strike a hard surface is known as refection.

<h3>3.0 Image formed by concave lens</h3>

A concave lens is diverging lens is usually virtual, erect and magnified.

<h3>4.0 Refraction of light</h3>

The change in speed of light when it travels from medium to another medium is known as refraction. Refraction is also, the ability of light to bend around obstacles.
