Answer:
B
Explanation:
The Southern Hemisphere reflects a tremendous amount of radiation during the December solstice.
Northern Hemisphere receives more of the Sun’s thermal energy than the Southern Hemisphere. in the situation when the North Pole is tilted toward the Sun.
What is Sun’s thermal energy?One of the most important renewable energy sources is solar thermal energy. Solar thermal systems transform solar energy into heat.
Which may be used directly or converted into electricity for use in any application that can be served by conventional power.
The Northern Hemisphere is located well above the Equator, whilst the Southern Hemisphere is located below it.
The hemispheres include distinct quantities of land, ocean, and sea, as well as varied populations and climate patterns.
When the North Pole is tilted toward the Sun the Northern Hemisphere receives more of the Sun’s thermal energy than the Southern Hemisphere.
Hence option b is correct.

3. A beam of light passes through the air (n=1.00) and enters a diamond (n=2.42) at an angle of incidence of 40 degrees. Use Snell’s Law to find the angle of refraction in the diamond. If the diamond is placed in a tank of water (n=1.33) and the beam of light enters the diamond at the same angle of incidence, what would be the new angle of refraction? Show all work.
Answer:
(a) θ₂ = 15.4°
(b) θ₂ = 28.9°
Explanation:
Snell's Law can be written as follows:
[tex]n_1Sin\theta_1 = n_2Sin\theta_2[/tex]
where,
n₁ = incident index
n₂ = refracted index
θ₁ = Angle of incidence
θ₂ = Angle of refraction
(a)
n₁ = incident index = 1
n₂ = refracted index = 2.42
θ₁ = Angle of incidence = 40°
θ₂ = Angle of refraction = ?
Therefore,
[tex](1)(Sin\ 40^o) = (2.42)Sin\theta_2\\\theta_{2} = Sin^{-1}(0.26561)[/tex]
θ₂ = 15.4°
(b)
n₁ = incident index = 1
n₂ = refracted index = 1.33
θ₁ = Angle of incidence = 40°
θ₂ = Angle of refraction = ?
Therefore,
[tex](1)(Sin\ 40^o) = (1.33)Sin\theta_2\\\theta_{2} = Sin^{-1}(0.4832)[/tex]
θ₂ = 28.9°

A mosquito's wings create a buzzing noise with a frequency of 1050 Hz. If you hear a mosquito buzzing with a frequency of 1034 Hz, at what velocity is the mosquito travelling with respect to you (in m/s)?
NO LINKS
Answer:
5.26 m/s
Explanation:
Given that,
The frequency of mosquito's wings, f = 1050 Hz
The observed frequency = 1034 Hz
We need to find the velocity of the mosquito travelling with respect to you. We have a formula to find it such that,
[tex]v=\dfrac{v}{\dfrac{f'}{f}}-v[/tex]
Where
v is the speed of sound
So,
[tex]v=\dfrac{340}{\dfrac{1034}{1050}}-340\\\\v=5.26\ m/s[/tex]
So, the required velocity is equal to 5.26 m/s/
Un avión despega a las 2:00 p.M en un vuelo de 2500 millas. El avión llega a su destino a las 7:30 p.M. Explicar por qué hay el menos dos momentos durante el vuelo en los que la velocidad del avión es de 400 millas por hora.
Answer:
Por lo tanto, cuando la velocidad promedio del avión es mayor que la velocidad de vuelo posible dada, entonces es posible tener dos puntos durante el vuelo cuando la velocidad es la de la velocidad dada
Explanation:
La hora de despegue del avión, t₁ = 2:00 p.m.
La distancia del vuelo que viaja el avión = 2,500 millas
La hora de llegada del avión al destino, t₂ = 7:30 p.m.
El tiempo de vuelo, Δt = t₂ - t₁
Por lo tanto, Δt = 7:30 - 2:00 = 5 horas 30 minutos = 5,5 horas
La velocidad media del avión,[tex]v_{ave}[/tex] = (Distancia total) / (Tiempo total)
= 2,500 millas / (5,5 horas) = 454. millas por hora
La velocidad promedio se puede encontrar también sumando velocidades individuales y dividiendo el resultado por el número de velocidades sumadas en la suma
Por ejemplo, tenemos;
∴ [tex]v_{ave}[/tex] = (v₁ + v₂ + v₃ )/3
Si durante el vuelo horizontal directo, la velocidad máxima, v₃ = 509 millas por hora, y v₁ y v₂ son puntos donde el avión se mueve en ángulo con la horizontal y, por lo tanto, velocidad horizontal reducida, entonces tenemos;
En el camino hacia arriba sobre una nube con velocidad horizontal v₁
454.[tex]\overline{54}[/tex] = (v₁ + 509)/2
2 × 454.[tex]\overline{54}[/tex] - 509 = 400.[tex]\overline{09}[/tex] = v₁
∴ v₁ = 400.[tex]\overline{09}[/tex] mph ≈ 400 mph
De manera similar, en el camino de regreso a la elevación del vuelo, tenemos v₂ = 400.[tex]\overline{09}[/tex] mph ≈ 400 mph
Por lo tanto, cuando la velocidad promedio del avión es mayor que la velocidad de vuelo posible dada, entonces es posible tener dos puntos durante el vuelo cuando la velocidad es la de la velocidad dada.
If an object that was held steady (0 speed) and then dropped, how many meters would it fall in one second?
Answer:
h = 4.905 m
Explanation:
In order to find the distance covered by the object in 1 second, we can use the second equation of motion:
[tex]h = v_i t + \frac{1}{2}gt^2\\[/tex]
where,
h = distance covered = ?
vi = initial speed = 0 m/s
g = acceleration due to gravity = 9.81 m/s²
t = time = 1 s
Therefore,
[tex]h = (0\ m/s)(1\ s)+\frac{1}{2}(9.81\ m/s^2)(1\ s)^2\\\\[/tex]
h = 4.905 m

The main reason for using light years, however, is because the distances we deal with in space are immense. If we stick to miles or kilometers we quickly run into unwieldy numbers just measuring the distance to the nearest star: a dim red dwarf called Proxima Centauri that sits a mere 24,000,000,000,000 miles away!

The standard cell potential (E°cell) for the reaction below is +0.63 V. The cell potential for this reaction is __________V when the concentration of Zn2+ = 1.0 M and the
concentration of Pb2+ = 2.0 x 10-4 M.
Pb2+(aq) + Zn(s) ---> Zn2+(aq) + Pb(s)
Answer:
0.52 V
Explanation:
From Nernst equation;
Ecell =E°cell - 0.0592/n log Q
E°cell = +0.63 V
[Zn2+] =1.0 M
[Pb2+] = 2.0 x 10-4 M
n = 2
Ecell = 0.63 - 0.0592/2 log[1.0/2.0 x 10-4]
Ecell = 0.63 - 0.11
Ecell = 0.52 V

300 grams of ethanol is heated with 14640 Joules of energy to reach a final temperature of 30 °C. What was the initial temperature of the ethanol? The specific heat of ethanol is 2.44 J/g·°C.
Answer:
10 °C
Explanation:
Applying
q = cm(t₂-t₁)............... Equation 2
Where q = heat energy, c = specific heat of ethanol, m = mass of ethanol, t₁ = initial temperature, t₂ = Final temperature.
Given: c = 2.44 J/g.°C, m = 300 g, q = 14640 J, t₂ = 30°C
Substitute into equation 2 and solve for t₁
14640 = 2.44×300(30-t₁)
14640 = 732(30-t₁)
732(30-t₁) = 14640
(30-t₁) = 14640/732
(30-t₁) = 20
t₁ = 30-20
t₁ = 10 °C
Answer:
30°C

Explain how a manufacturing business might participate in the ""resource disposal"" aspect of resource management.
Answer:
Resource disposal or waste disposal is a crucial aspect of resource management.
Businesses in the manufacturing sector must develop a model of operations that allows an endless loop of internal recycling of waste and or processing waste resources into commercial resources.
A good example would be when an abattoir processes the internal organs of cows and goats with some waste gotten from rice mill into can food for dogs and canines. Waste from this secondary process can either be converted into organic manure to be sold to farmers or processed further for consumption at carnivorous fish farms.

Please help me with a speech.The topic of my speech is Passion.
Answer:
Explanation:
Passion
For me, standing on the summit of Mt Everest was the result of following a process. The process of mountaineering. I love mountaineering. I am passionate about it. I love the months of planning for an expedition, the months of sweating and training to prepare my body physically. The meticulous preparation of my equipment. Most of all I love the huge mental challenge I have to overcome before each climb to confront my own fear. All these reasons are why I climb, they are why I climbed Mt Everest and that is why I continue to climb.
Passion is an enormously powerful force. It gives us the strength to get through hard times and setbacks. It gives us strength to overcome our fears, to ignore what other people think of us, to be disciplined and make sacrifices in pursuit of our dreams. Passionate people do not want to take shortcuts – they consider that ‘learning the process’ is an important part of the journey.
In mountaineering it’s easy to spot those who are not passionate about the process. They want to stand on top of the mountain but they are not really interested in the process of climbing the mountain. I feel for these people. Success without hard work is a hollow, empty feeling. They never last long in the sport.
Just as in life, successful mountaineers are the ones who are passionate. They are not there just to stand on the summit. Their passion gives them the energy to work the hardest, fight the longest, and in the words of Winston Churchill “never, never. never give-up”.
