Answer:
a). Determine the magnitude of the gravitational force exerted on each by the earth.
Rock:
Pebble:
(b)Calculate the magnitude of the acceleration of each object when released.
Rock:
Pebble:
Explanation:
The universal law of gravitation is defined as:
(1)
Where G is the gravitational constant, m1 and m2 are the masses of the two objects and r is the distance between them.
<em>Case for the rock </em><em>:</em>
m1 will be equal to the mass of the Earth and since the rock and the pebble are held near the surface of the Earth, then, r will be equal to the radius of the Earth .
Newton's second law can be used to know the acceleration.
(2)
<em>Case for the pebble </em><em>:</em>
In which it is the plane in which charges move. for example in electromagnetic waves polarization<span> means the plane in which electrons oscillate. ... it is the distribution of electric charges (electron) in an object. </span>induction<span> of charges takes place in some insulators just by some mechanical interaction such as rubbing</span>

The student's conclusion shows experimental bias
Just because most of nis classmates like puffed cereal ,it is inappropriate to conclude puffed cereal is better than oats cereal
Answer:
can a fire have a shadow?
Yes it can actually.
edit:Fires can have shadows because they contain hot air and soot, and not because they contain light.
