Voting rates among lower-educated, lower-paid workers are lower than for people with higher socioeconomic status. Workers in low-paying service jobs might find difficulties to get to the polls. Social class may be linked to race and ethnicity because a larger share of racial and ethnic minorities is employed in positions that have no flexibility in work hours or someone to take care of their children. Some people of low socioeconomic status doubt their vote will count because they have seen no evidence of their political power in their communities (a system in which people with more power have the means to perpetuate their power).
Michel Feld is an MIT professor who had an amazing track record of mentoring African-American scientists, which included the astronaut Ronald McNair, who later received his PhD under the supervision of the former. Both of them together came up with the Physics of Karate.
Physics of Karate gives us a close examination on how a karate expert can break wooden and concrete blocks using only his hands, which reveals the remarkable capacity of human body, which has been left unaided, yet it exerted such amount of physical force.
Thus, Michel Feld and Ronald McNair came up with the concept of science and philosophy behind the martial arts.

Explanation:
The answer is D aluminum (density = 2.7g/mc3).
A density (D) of a substance is a quotient of its mass (m) and its volume (V):
D = m/V
It is given:
m = 13.5 g
V = 5 cm³
Therefore:
D = m/V = 13.5/5 = 2.7 g/cm³
Among all choices, only aluminum has density of 2.7 g/cm³.
