Answer:
The force increases because it is part of a Newton’s third law pair of forces with the force that the star exerts on the planet.
Explanation:
Force between two objects can be expressed by an equation:
F = G • m1 • m2 / r^2,
where m1 and m2 are objects' masses, r is the distance between them, and G is a gravitational constant.
That means that greater the masses or lesser the distance, the force will be greater, and vice versa.
This force exists between any two objects, but is generally extremely weak, so it's best observed with big and large objects with great mass, such as planets and stars.
This force, whatever its magnitude may be, always works on both objects, following the third Newton's law.
So, whatever the force the stat exerts on the planet is, the planet will exert the same amount of force on the star.
Answer:
A
Explanation:
because it can share and remain with ither electrons
Answer:
D. Phototropism
Explanation:
Plants, like every other living organism, responds to external stimulus. In this question, the stimulus is LIGHT from the sun entering through the window sill. The plant is responding positively to the light stimuli by growing towards the direction where the light is coming from. This exhibit is called PHOTOTROPISM.
Phototropism, comes from two words viz photo- meaning light and tropism- meaning movement. Hence, phototropism is the growth of an organism (plant in this case) in response to a light stimulus. The case described in this question is POSITIVE PHOTOTROPISM because the growth occurs towards the light source.

Answer:
Explanation:
Chemical properties of atoms relies solely on the number of electrons they contain, more particularly, the valence or outermost electrons in the orbit round the nucleus of an atom.
A neutral atom is one that has not gained or lost electron or even shared electrons with any other atom.
On close examination of how electrons are distributed in the orbits of an atom, we can know if an atom will gain or lose electrons in a reaction. This is very important in determining the chemical properties of an atom.
