physics, electromagnetic radiation refers to the waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays.
Answer:
F = 0.84 [N]
Explanation:
In order to solve this problem we must take into account Newton's second law, which tells us that the sum of all forces applied on a body must be equal to the product of the mass of the body by its acceleration.
F = m*a
where:
F = force [N]
a = acceleration = 1.4[m/s^2]
m = mass = 0.6 [kg]
F = 0.6*1.4
F = 0.84 [N]
Im pretty sure it’s a because it makes more sense you know?.
Answer:
, attractive.
Explanation:
For calculating this force we use the Coulomb Law:

Where
is the Coulomb's constant,
and
the values of each charge and r the distance between them.
Since the Coulomb's constant as I wrote it is in S.I. we have to write all the magnitudes in that system of units, and substitute:

This force is attractive since both charges are of opposite sign.
