Answer:
17.7MN
Explanation:
Given Data
m1 = 5.98 x 10^24 kg
m2= 15,000 kg
R= 6.378 x 10^6 m+575-km
R= 6.378 x 10^3+575*10^3-km
R= 581378m
G = 6.673 x 10-11 N m^2/kg2
This net centripetal force is the result of the gravitational force that attracts the satellite towards the central body and can be represented as
F =GM1M2 / R^2
F =6.673 x 10-11* 5.98 x 10^24*15,000 / 581378^2
F =6.673 x 10^-11* 5.98 x 10^24*15,000 / 581378^2
F= 39.90454*10^13*15,000/ 581378^2
F= 598.5681*10^16/338000378884
F= 17709095.5335N
F= 17.7MN

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
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.

the total resistance of the circuit
The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω
Current: The total circuit current is equal to the sum of the individual branch currents. Resistance: Individual resistances diminish to equal a smaller total resistance rather than add to make the total.
Answer: 3
Explanation: If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

the last option
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.

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.

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.

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.
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.

.- 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.
