List 5 plants or animals that the emporer penguin eats
Answer:
Emperor penguins are near the top of the Southern Ocean’s food chain. They have a varied menu that changes with the season. Some prey items are more important than others. One of the most frequently eaten prey species is the Antarctic silverfish Pleuragramma antarcticum. They also eat other fish, Antarctic krill and some species of squid. Most prey items are small. Since they are very cold when ingested, their small size makes it easier to bring food up to body temperature to digest it.

What was the runoff from precipitation on the property for areas with vegetation and roofed or paved areas over the past four months? What percent of total precipitation ran off of the property? Include data tables in your answer. Would you expect this percentage to be the same for the properties of other students in the class? Why or why not? What factors decide the percentage of runoff?
Answer:
Higher percentage of runoff water is absorbed by the vegetation whereas 100 % of water runoff on the roofed area.
Explanation:
Higher percentage of runoff water is absorbed by the vegetation and very little amount of runoff water is received on the end of vegetative cover while on the other hand, 100 percent of precipitation water runoff on the surface of roofed or paved area because no water is absorbed by the roof due to its solid surface. The percentage of runoff depends on the factors such as rainfall intensity, slope, soil water storage capacity, and infiltration rate.

Which of these does not represent a direct transfer of carbon
1.Air to trees
2.Giraffe to tree
3.Tree to giraffe
Answer:
The correct answer is - 2. Giraffe to trees.
Explanation:
In the carbon cycle, the movement of carbon is represented how it moves from one sphere to other and how it transfer among the different organism. The carbon moves from air to the trees in the form of carbon dioxide that is used by trees for the production of glucose by the process of photosynthesis through stomata.
The movement of the carbon among trees to different herbivores including giraffe is transferred by the eating of the leaves or fruits of the tree that carries glucose or starch. The transfer of carbon through giraffe does not take place directly but takes the release of carbon dioxide by the process of cellular respiration to the atmosphere.
The electric potential 5.54 m from
a charge is -3680 V. What is the
value of the charge?
Include the sign, + or - .
(The answer is *10^-6 C. Just fill in
the number, not the power.)
Answer:
q = - 2.26 x 10⁻⁶ C
According to answering format:
q = - 2.26
Explanation:
The potential at a distance r from a charge q is given as follows:
[tex]V = \frac{kq}{r}[/tex]
where,
V = Potential = -3680 V
k = Colomb's Constant = 9 x 10⁹ Nm²/C²
r = distance = 5.54 m
Therefore,
[tex]-3680\ V = \frac{(9\ x\ 10^9\ Nm^2/C^2)q}{5.54\ m}\\\\q = \frac{(-3680\ V)(5.54\ m)}{9\ x\ 10^9\ Nm^2/C^2}[/tex]
q = - 2.26 x 10⁻⁶ C

Based on the information in the graph, why is energy released during the fusion of hydrogen (H) into helium (He)?
A. The hydrogen-1 nuclei (H - 1) are more stable than the helium-4 (He - 4) nucleus is, because they have less binding energy per nucleon than the helium has.
B. There are fewer nucleons in a helium-4 (He-4) nucleus than there are in four hydrogen-1 (H - 1) nuclei, so there is more energy released per nucleon when helium forms.
C. The hydrogen (H) nuclei are lower in energy than the helium (He) nucleus is, so more energy is stored in a helium nucleus.
D. The helium (He) nucleus is more stable than the hydrogen (H) nuclei are, because more mass is converted into binding energy in helium.
Answer:
D
Explanation:
Just had the same question and couldnt find and answer so i guessed. heres the answer no lol!
Answer: D.The helium (He) nucleus is more stable than the hydrogen (H) nuclei are, because more mass is converted into binding energy in helium.

.- Una esfera hueca de acero a 28°C tiene un volumen de 0.4 m³, calcular a) ¿qué volumen final tendrá a -6°C en m³ y en litros? B) ¿Cuánto disminuyó su volumen en litros?
Answer:
Ve respuesta abajo.
Explanation:
Para hacer esto, podemos asumir que la presión es constante, pues es un proceso adiabatico, por tanto se aplica la ley de Charles a presión constante:
V₁/T₁ = V₂/T₂ (1)
De ahí podemos despejar V₂, ya que conocemos las condiciones iniciales de temperatura y volúmen, y la temperatura final:
V₂ = V₁ T₂ / T₁ (2)
Las temperaturas deben estar en grados Kelvin, y solo es cuestión de sumarle 273 al valor de la temperatura dada en °C:
T₁ = 28 + 273 = 301 K
T₂ = -6 + 273 = 267 K
El volúmen podemos pasarlo a litros ahora o al final. En este caso, podemos dejarlo en m³ como está y luego pasarlo a Litros. Resolviendo tenemos:
V₂ = 0.4 * 267 / 301
V₂ = 0.35482 m³Pasando este volumen a Litros, sabiendo que 1 m³ son 1000 L:
V₂ = 0.35482 * 1000
V₂ = 354.82 LFinalmente para saber cuanto disminuyó el volumen en Litros, pasemos el volumen inicial a Litros y luego se hace la resta con el volumen final:
V₁ = 0.4 * 1000 = 400 L
V₁ - V₂ = 400 - 354.82
V₁ - V₂ = 45.18 LEsto es lo que disminuyó. Espero te ayude.

Healthy human lungs look pink and spongy from the outside. The left lung is a little smaller than the right lung to make room for the heart. The lungs and heart are both protected by the rib cage. In the lungs, each main bronchus branches off into many smaller bronchi. The bronchi become smaller and smaller, and the smallest bronchi are called bronchioles. There are about 30,000 bronchioles in each lung, each about the same thickness as a strand of hair. The inhaled air eventually ends up in tiny air sacs called alveoli at the end of each bronchiole. There are about 300 million alveoli in each lung. They are covered with capillaries, tiny blood vessels that are only one cell thick. Oxygen travels from the alveoli through the capillaries to the bloodstream, heart and other cells
Which of these best represents the progression of bronchi, bronchioles and alveoli in the lungs?
A tree trunks that become smaller branches and twigs
B a tight flower bud that has opened into a full bloom
C whole apples that are sliced into separate wedges

Explanation:
A 110 kg football player running with a velocity of 5.0 m/s hits another stationary football
player who has a mass of 90 kg. Upon impact, the first player immediately stops, thus propelling
the second player backwards. What is the final velocity of the second player?
Answer:
The final velocity of the second player is 6.1 m/s.
Explanation:
The final velocity of the second player can be calculated by conservation of linear momentum (p):
[tex] p_{i} = p_{f} [/tex]
[tex] m_{a}v_{a_{i}} + m_{b}v_{b_{i}} = m_{a}v_{a_{f}} + m_{b}v_{b_{f}} [/tex] (1)
Where:
[tex]m_{a}[/tex]: is the mass of the first football player = 110 kg
[tex]m_{b}[/tex]: is the mass of the second football player = 90 kg
[tex]v_{a_{i}}[/tex]: is the initial velocity of the first football player = 5.0 m/s
[tex]v_{b_{i}}[/tex]: is the initial velocity of the second football player = 0 (he is at rest)
[tex]v_{a_{f}}[/tex]: is the final velocity of the first football player = 0 (he stops after the impact)
[tex]v_{b_{f}}[/tex]: is the final velocity of the second football player =?
By solving equation (1) for [tex]v_{b_{f}}[/tex] we have:
[tex] 110 kg*5.0 m/s + 0 = 0 + 90 kg*v_{b_{f}} [/tex]
[tex] v_{b_{f}} = \frac{110 kg*5.0 m/s}{90 kg} = 6.1 m/s [/tex]
Therefore, the final velocity of the second player is 6.1 m/s.
I hope it helps you!

Because cosmic distances are so vast, astronomers use light-years as their unit of distance. One light-year is defined as _______________________. The nearest star is a little more than ____ light-years away from us. When we see light from a galaxy 2 million light-years away, it has taken _______________ to reach us. Light from the Sun takes ___________ to reach us.
Answer:
Because cosmic disaster are so vast, astronomers use light-years as their unit of distance. One light-year is defined as the distance a beam of light travels in one year. The nearest star is a little more than 4.37 light-years away from us. When we see light from a galaxy 2 million light-years away, it has taken 2 million Earth years to reach us. Light from the Sun takes approximately 8.4269 minutes to reach us
Explanation:
i) One light-year is defined as the distance a light beam travels in a time of one Earth year. One light year is equivalent to 6 × 10¹² miles or 9.7 × 10¹² km
ii) The distance to the nearest star = 4.37 light-years
iii) When a star located in a galaxy that is 2.3 million light years away is seen, it has taken 2.3 million light years to reach us
iv) The distance of the Sun to the Earth = 151.58 million kilometers
The speed of light, c = 299792.458 km/s
The time it will take light to reach us from the Sun, 't', is given as follows;
t = 151.58 × 10⁶ km/(299792.458 km/s) ≈ 8.4269 minutes.

¿Cuál de la plantas generadoras de electricidad te parece que tiene mas respeto por el medio ambiente?
what happens to an electromagnetic wave as it passes from space to matter?
(no keyboard spam or links)
I'll give brainiest
Answer:
When an electromagnetic wave passes from space to matter, some part of the energy is absorbed by the matter and it increases its energy. The wave may reflect and some part may pass through the matter depending on the amount of energy they have. The amplitude of the wave decreases if some parts of it are reflected.
Electromagnetic radiation is one of the many ways that energy travels through space. The heat from a burning fire, the light from the sun, the X-rays used by your doctor, as well as the energy used to cook food in a microwave are all forms of electromagnetic radiation. While these forms of energy might seem quite different from one another, they are related in that they all exhibit wavelike properties.
