Imagine that a new planet is discovered with two moons of equal mass: Moon A and Moon B. The mass of the new planet is greater t
han the combined mass of its moons. Moon A is farther away from the new planet than Moon B. What is the planet's gravitational pull on Moon A compared to the planet's gravitational pull on Moon B? The planet's gravity repels Moon A with a greater force than it repels Moon B, which is why Moon A is farther away.
The gravitational pull on Moon B is greater than on Moon A because Moon B is closer to the new planet than Moon A.
The gravitational pull on Moon B is greater than on Moon A because Moon B is farther away from the new planet than Moon A.
The gravitational pull on Moon A is the same as the gravitational pull on Moon B because distance does not affect the planet's gravity.
Answer: The gravitational pull on Moon B is greater than on Moon A because Moon B is closer to the new planet than Moon A.
Explanation:
The gravitational force exerted by the two objects on each other is inversely proportional to the square of the distance between the objects.
F = gravitational force or pull
G = gravitational constant on that planet
M = mass of the object-1
m = mass of object-2(Mass of Moon-A or Moon-B)
r = distance between two objects
With decease in distance 'r' the force between the object increases or vice versa.So, from this we can say that the gravitational pull on Moon-B is more than the gravitational pull on Moon-A because the Moon B is closer than the Moon-A from the new planet.
According to Diagram B, look at the 1600 elevation until you see the descending air line touches it. Then look down at the temperature at the bottom of the graph. It is between 0 degrees to 5 degrees.
The only number that is between that range is 2 degrees C.
Conduction is a form of heat transfer between one body and another. It usually occurs when a warmer object is in contact with a cooler one. Heat generally flows from a region of high temperature to a place at a lower temperature.
Conduction is very pronounced in solid bodies.
The heat transfer causes a net transfer of the average kinetic energy of one body to the other.
Some examples are: heating of iron by a hotter metallic body, the pot hand getting hotter as cooking continues, cooling of ice by touching it.
The correct answer among the choices given is option B. Radioisotopes are isotopes that emit radiation because they have unstable nuclei. These are radioactive isotopes of an element. They are defined as atoms that contain an unstable combination of neutrons and protons.
