The answer would be oceanography.
Explanation:
Resistance = Resistivity * Length / Area
= 30 * (1/3) / (1/4)
= 40x.
Hence the resistance of the constant wire is 2 * 40 = 80 ohms.
Answer:
(a)
(b)
Explanation:
Hello.
(a) In this case, since the initial volume is 18.5 dm³ and the final volume is 21 dm³ (18.5 +2.5), we can compute the work at constant pressure as shown below:
Which is negative as it expands against the given pressure.
(b) Moreover, of the process is carried out reversibly, the pressure can change, therefore, we need to compute the work via:
Whereas the moles are computed from the given mass of argon:
Thus, the work is:
Regards.
Answer:
D. Community members, teachers
Explanation:
The Highscope curriculum encourages community members to have a very active role in the learning of each child, helping in their development. The activities are child-initiated and guided by parents and community members in general, having a role of partners, contrary to the role that they traditionally had as supervisors.
