Can somebody help me with this i cannot learn it online, a walk through would be nice :)

Answer: The green house effect is best described by option 4 (Energy given off by earth is reflected off of earth's atmosphere back down to the surface).

Explanation:

The green house effect can be described as the energy given off by earth is reflected off of earth's atmosphere back down to the surface.

When energy from the sun passes through the atmosphere, some are absorbed which keeps the earth surface warm. While the rest is reflected back largely by cloud.

The energy which is emitted from the earth surface is called the infrared radiation. Some of the infrared radiation passess through the atmosphere but most is absorbed and re- emitted in all directions by the greenhouse gas molecules and clouds. This effect warms the earth surface and the lower atmosphere. Therefore this statement (Energy given off by earth is reflected off of earth's atmosphere back down to the surface) is correct about greenhouse effect.

For the greenhouse effect to occur, greenhouse gas molecules are mostly needed. Examples of these gases include:

--> Carbon dioxide (CO2),

--> Water vapor (H2O), and

--> Methane (CH4)

Over the years, the excessive human activities has lead to increase in the greenhouse gas molecules which has negatively affected the greenhouse effects.

Answer:

Fats and waxes are solid at room temperature because they are made of saturated fatty acids. In contrast, oils are mostly unsaturated fatty acids. ... In contrast, unsaturated fatty acids have several kinks in their structure and therefore, are liquid at room temperature.

Answer: Downwards

Explanation: Upwards is only at the start of a thunderstorm when air moves towards the poles. During the mature stage, air moves down towards the equator.

The image of the map is missing, so i have attached it.

Answer:

The air temperature at oribus is warmer than the air temperature at Delphina.

Explanation:

Looking at the map, we can say that he wind will push ocean water that is turning and passing the coasts. Now, as a result, Energy will be transferred from the ocean to the air at Oribus and whereas energy is transferred from the air to the ocean at Delphina. Thus, the air temperature at Oribus will be warmer than that at Delphina.

Answer:

Total distance = 2πr

Total displacement = 0

Explanation:

To Calculate the magnitude of distance and displacement of a body moving in a complete circle, we must come to these facts that:

The distance = circumference of the circle which is equal to the product of 2 ,pi and radius r

That is

Circumference = 2πr

Since velocity is changing and not constant, it is a vector quantity. Likewise displacement is a vector quantity.

The total displacement will be equal to zero.

Therefore, total distance is equal to the circumference of a circle while total displacement is equal to zero.

Answer:

B. the same forest as the force of the table pushing up on the object of interest

Answer:

60 kWh

Explanation:

The computation of the annual energy consumption in KW-h is shown below:

As we know that

1 kw = 1000 w

So, for 1400 W it would be

= 1,400 ÷ 1,000

= 1.4 kW

Now the number of hours it used in a year

= 7 minutes × 365 days ÷ 60 minutes

= 42.58333 hours

So in one year it used

= 1.4 kW × 42.58333

= 59.61 kWh

= 60 kWh

Answer:

E = 7200 J = 7.2 KJ

Explanation:

The electric field due to a sphere is similar to the electric field due to a point charge. It is calculated by the use of the following formula:

[tex]E = \frac{kq}{r^2}\\[/tex]

where,

E = Electric Field = ?

k = Coulomb Constant = 9 x 10⁹ Nm²/C²

q = charge on sphere = 2 μC = 2 x 10⁻⁶ C

r = distance from the center of the sphere to the location = 5 cm = 0.05 m

Therefore,

[tex]E = \frac{(9\ x\ 10^9\ Nm^2/C^2)(2\ x\ 10^{-6}\ C)}{(0.05\ m)^2}[/tex]

E = 7200 J = 7.2 KJ

Answer:

Waves; wavelength; electromagnetic energy; ultraviolet light.

Explanation:

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Sound travels faster through solids than it does through either liquids or gases.

Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

Hence, sound and light are both found as waves, with a variety of wavelength. The sun, a source of light waves specifically, releases a type of electromagnetic energy. It can be found as UVA or UVB types. These lights give off different levels of ultraviolet light, some of wich can be harmful.

Additionally, the ultraviolet spectrum is divided into three categories and these are; UVA, UVB and UVC.

Following are the response to the fill in the blanks:

Therefore, the answer is "Waves, wavelength, electromagnetic energy, ultraviolet light".

Answer:

x = 0.78 m = 78 cm

Explanation:

Applying the law of conservation of energy to the spring-mass system, we can write the following equation:

[tex]Kinetic\ Energy\ at\ Mean\ Position= Potential\ Energy\ at\ extreme\ position\\\frac{1}{2}mv^2 = \frac{1}{2}kx^2\\\\x^2 = \frac{mv^2}{k}\\\\x = \sqrt{\frac{mv^2}{k} }[/tex]

where,

x = maximum displacement = ?

m = mass = 3.6 kg

v = speed at mean position = 5.2 m/s

k = spring constant = 160 N/m

Therefore,

[tex]x = \sqrt{\frac{(3.6\ kg)(5.2\ m/s)^2}{160\ N/m} }\\\\[/tex]

x = 0.78 m = 78 cm

Answer:

The charge on each end of the wire produces what we call an electric field. The electric field makes negative electrons want to travel towards the positive end of the wire (the end with not enough electrons).

the answer is d because it's going to positive.
