bonded pairs of electrons, lone pairs of electrons.
Answer:
See the explanation below.
Explanation:
We know that density is defined as the relationship between mass and volume.
where:
m = mass [kg]
V = volume [m³]
Therefore Ro is given in:
![[kg/m^{3} ]](https://tex.z-dn.net/?f=%5Bkg%2Fm%5E%7B3%7D%20%5D)
According to the net force, the acceleration of the book is 16.47 m/s².
We need to know about force to solve this problem. According to second Newton's Law, the force applied to an object will be proportional to mass and acceleration. Hence, it can be written as
∑F = m . a
where F is force, m is mass and a is acceleration
From the question above, we know that
m = 3 kg
g = 9.8 m/s²
F1 = 20 N
Find the net force
∑F = F1 + W
∑F = 20 + m . g
∑F = 20 + 3 . 9.8
∑F = 20 + 29.4
∑F = 49.4 N
Find the acceleration
∑F = m . a
49.4 = 3 . a
a = 16.47 m/s²
