Newton's universal law of gravitation states that all objects attract each other with a force directly proportional to their masses and inversely proportional to the square of the distance between their centers. When considering objects on the surface of the Earth, the force is directly proportional to the product of the mass of the object and the acceleration due to gravity at the Earth's surface. Since the Earth is larger than any other object under consideration, the object is drawn toward the Earth.

Explanation:

The magnitude of the gravitational force between two objects is given by  Newton's universal law of gravitation:

F=G\frac{m_1 m_2}{r^2}

where :

G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2} is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

This force is always attractive.

At the Earth's surface, this can be rewritten as

F=mg

with

g=\frac{GM}{R^2}

where M is the mass of the Earth, R is its radius, and m the mass of the object.

g is called acceleration due to gravity and it is the value of the acceleration due to the force of gravity of any object near the Earth's surface (its value is approximately 9.81 m/s^2. Since the Earth is much more massive than any other object, the object is attracted towards the Earth (so, it accelerates towards it); the Earth is also attracted by the object, however, being its mass so large, its acceleration is negligible.

Which organelle sends out microtubules that connect to DNA during Metaphase?
katrin [286]
Hey friend!
You stuck?

The organelle that sends out microtubules that connect to DNA during Metaphase are called centrioles. The connect to the DNA during metaphase, during that process they determine the position of the nucleus.  


Hope this helps! :)

Why is the Calvin cycle also called the light-independent reactions?<br>​
Slav-nsk [51]

Answer:

These reactions are also called the light-independent reactions because they are not directly driven by light. ... Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
