In the first case, once equilibrium is established,
mg = kx
135 = k(0.21) [Converted to SI units]
k = 135/(0.21)

In the second case, similarly when reaching equilibrium,
mg = kx
mg = [(135)(.449)]/(0.21)
mg = weight of the electronic equipment = approximately 289 N.

Answer:

F= 288.7 N

Explanation:

According to Hooke's Law

"the strain or deformation experienced by an elastic body is directly proportional to the stress applied to it."

We can calculate the spring constant using Hooke's Law:

F = k*x

therefore,

k = F/x

k = 135N/0.21m

k = 643 N/m

When the fish stretches the spring by 0.449m, its weight would be

F =k*x

F= 643N/m * 0.449m

F= 288.707 N

In what processes do proteins in the electron transport chain participate?
kicyunya [3294]

Answer:

1. Reactions involving oxidation and reduction along with proton pumping

2. Reactions involving phosphorylation and proton pumping

Explanation:

During oxidative phosphorylation, there is a transfer of electrons from donors to acceptors, which constitutes a redox reaction.

These redox reactions liberate energy that is utilized to produce ATP. In eukaryotic cells, these reactions are performed by protein complexes found in the mitochondria, while in prokaryotic cells, the proteins are positioned in the intermembrane space of the cells. These interconnected protein complexes are referred to as electron transport chains.
