Answer: yes because all densities can be simplifed it just depends on the number.
Answer:
2.30 × 10⁻⁸ N if the two electrons are in a vacuum.
Explanation:
The Coulomb's Law gives the size of the electrostatic force
between two charged objects:
,
where
is coulomb's constant.
in vacuum.
and
are the signed charge of the objects.
is the distance between the two objects.
For the two electrons:
.
.
.
The sign of
is negative. In other words, the two electrons repel each other since the signs of their charges are the same.
The only electromagnetic wave that human eye can see or sensitive are those of visible light waves. These are colors representing the color of rainbow(red, orange, yellow, green, blue, and violet). Red, which appears in the outermost shell of the rainbow, has the longest, wavelength, around 620-750 nm

Answer:
W_apparent = 93.1 kg
Explanation:
The apparent weight of a body is the weight due to the gravitational attraction minus the thrust due to the fluid where it will be found.
W_apparent = W - B
The push is given by the expression of Archimeas
B = ρ_fluide g V
ρ_al = m / V
m = ρ_al V
we substitute
W_apparent = ρ_al V g - ρ_fluide g V
W_apparent = g V (ρ_al - ρ_fluide)
we calculate
W_apparent = 980 50 (2.7 - 0.8)
W_apparent = 93100 g
W_apparent = 93.1 kg
