According to newtons 3rd law, every force has an equal and opposite force, which means that the answers for a and b should be the same.
you might be knowing the equation of F which is
F = G(m1)(m2)/(r^2) (<em> this formula may be wrong, look it up on google)</em>
G is the universal gravitation constant, just google for the exact value, the value should be something like 6.67E-11
m1 is the mass of an apple
m2 is the mass of an orange
r is the distance between them ( should be squared)
Answer:
Preoperational
Explanation:
According to Piaget's theory of cognitive development, the preoperational stage is the second stage. This stage includes children between the age group of 2 to 7 years. Children can understand conservation tasks and learn to manipulate various symbols during this stage.
So, the answer is the preoperational stage.
Answer:I think it’s because both can provide heat and cold
Explanation:
Answer:
Planet C
Explanation:
The figure of the problem is missing: find it in attachment.
The magnitude of the gravitational force between two objects is given by the equation:

where
G is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between the objects
In this problem, we have four planets around planet X, and the mass of each planet is proportional to its size in the figure.
As we can see from the previous equation, the magnitude of the gravitational force is proportional to the mass of the planets: therefore, the planet with largest mass will exert the largest gravitational force on planet X.
From the figure, we see that planet C has the largest size, so the largest mass: therefore, planet C exerts the greatest gravitational force on planet X.
Mass of the milkyway galaxy :

The magnitude of the mass of the Milky Way galaxy = 
<h3>Can galaxies recycle stars?</h3>
Galaxies do not appear to have sufficient matter inside them to keep shaping modern stars at the rates that they do. Presently, astronomers have caught a universe within the act of reusing fabric that it already tossed out, which may clarify the discrepancy. New perceptions give the primary coordinate evidence of gas streaming into distant galaxies that are effectively making infant stars, offering support for the "galactic recycling" theory.
