Answer:
sun, earth, capitol building, human, atom
Explanation:
Gravity is directly proportional to the size of an object. Therefore, the object with the most mass will have the greatest force of gravity. We know this from the equation. 
Explanation:
Activation energy and reaction rate
The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. ... The released energy helps other fuel molecules get over the energy barrier as well, leading to a chain reaction.
Answer:
its a compass rose or a temperature that tells how is it hot or cold or it is to u where to go when needed like a map.And the angles is 6
Explanation:
Answer:
B. 2.77 x
N
Explanation:
The required force can be calculated by:
F = 
Where F is the force between the particles, K is the coulomb's constant (9 x
),
is the charge on the first particle,
is the charge on the second particle and
is the distance between the particles.
So that:
F = 
= 
= 2.7692 x
The force between the particles is 2.77 x
N.
