<h3><u>Answer;</u></h3>

Oligotrophic lake

A newly formed is most likely <u>oligotrophic lake</u>

<h3><u>Explanation;</u></h3>
  • Trophic state of a lake is determined by the amount of biologically useful nutrients dissolved in the waters of the lake.
  • A lake or a water body may be oligotrophic, eutrophic, mesotrophic and hypereutrophic.
  • An oligotrophic lake is a type of lake that has a low productivity due to low nutrient content in the lake. Waters in these types of lakes are clear due to a limited growth of algae in the lake.

PART ONE
Arte-miy333 [17]

Explanation:

Pressure = force / area

P = (68 kg × 9.8 m/s²) / (2 × (0.04 m)²)

P = 208,250 Pa

Converting to psi:

P = 208,250 N/m² × (0.225 lbf/N) × (0.0254 m/in)²

P = 30.2 psi

Two facing surfaces of two large parallel conducting plates separated by 8.5 cm have uniform surface charge densities such that
elena-s [515]

Answer:

positive plate

E = 5.764 KV / m

W = 490eV or 7.85 * 10^-17 J

E_p = 4.74 *10^(-12) eV

E_k = 490 eV

Explanation:

part a

The potential difference between two plates = 490 V

Distance between two plates = 8.5 cm

Answer: The positive plate is at higher potential because of convention.

part b

Electric Field between the plates

E = V / d

E = 490 / 0.085 = 5.764 KV / m

Answer: Electric Field between the plates E = 5.764 KV / m

part c

Work done by electric field

W = V*q

W = 490 * 1.602*10^-19

W = 7.85 * 10^-17 J

or W = 490 eV

Answer: Work done by electric field W = 490eV or 7.85 * 10^-17 J

part d

Potential Energy of an electron gained:

E_p = m_e * g * d / (1.602*10^-19)

E_p =  9.109*10^-31* 9.81 * 0.085 / (1.602*10^-19)

E_p = 4.74 *10^(-12) eV

Very very small E_p approximately 0

Answer: Potential Energy of an electron gained E_p = 4.74 *10^(-12) eV or 0.

part e

Kinetic Energy of an electron gained:

W - E_p = E_k

E_k = 490eV - 4.74*10^(-12)eV

E_k = 490 eV

Answer: Kinetic Energy of an electron gained E_k = 490 eV
