Ionic solutes are considered strong electrolytes. What does this mean for the conductivity of the solution?
A) Strong electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.
B) Strong electrolytes dissolve and do not dissociate in water providing no charged ions to conduct electricity.
C) Being a strong electrolyte refers the type of bonding and has no bearing on conducting electricity.
D) Strong electrolytes do not dissolve in water and can not conduct electricity.
ANSWER:
A) Strong electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.

Answer:
C . All of the different types of electromagnetic waves
Answer:
a) F = 1.26 10⁵ N, b) F = 2.255 10³ N, c) F_ {soil} = 3078 N
Explanation:
For this exercise we will use the relationship between momentum and moment
I = Δp
F t = p_f -p₀
a) with stiff legs, final speed is zero, initial velocity is down
Ft = 0-p₀
F = m v / t
let's calculate
F = 84.0 6.82 / 4.56 10⁻³
F = 1.26 10⁵ N
b) bending the legs
let's calculate
F = 84.0 6.82 / 0.254
F = 2.255 10³ N
c) It is requested to calculate the force of the ground on the man
∑ F = F_soil -W
F_soil = F + W
F_ {soil} = 2.255 103 + 84 9.8
F_ {soil} = 3078 N
B. Venus hope this helps have a great day
