Answer:
Social media and the internet at large played an important role in the facilitation of interaction and communication among people who participated in political protests. These protesters made use of social media to organize both pro and anti-governmental demonstrations, pass information to members about the activities of the protests, and also raise both global and local awareness of how the events unfolded.
The utilization of social media in political movements helped in providing opportunities for activists in the formation of online identities for the protest groups. In this light, social media helped in the promotion of competition in the political systems and dialogue.

Answer:
C. mass
Explanation:
Properties such as conductivity and density are usually normalized, so usually do not depend on sample size. While the amount of heat required to melt a sample will depend on its size, the actual melting point temperature does not.
Of the items on your list, "mass" is the one that depends on sample size. In fact, we usually describe the size of a sample in terms of its mass.
The time it takes for 1g of strontium-90 to decay to 250 mg is; 57.6 years
<h3>What is the half life of an element?</h3>
The formula for half life is;
A(t) = A₀ * (¹/₂)^(t/t_1/2)
Where;
A(t) is amount left after t years
A₀ the initial quantity of the substance that will undergo decay;
t_1/2 is the half-life of the decaying quantity.
We are given;
t_1/2 = 28.8 years
A₀ = 1 g
A(t) = 250 mg = 0.25 g
Thus;
0.25 = 1 * (¹/₂)^(t/28.8)
log 0.25 = (t/28.8) log (1/2)
-0.60206 = (t/28.8) * -0.3010
t = 2 * 28.8
t = 57.6 years
