A wire that is 0.36 meters long moves perpendicularly through a magnetic field at a speed of 0.21 meters/second. The induced emf
2 answers:
Answer:
Magnetic field strength,
Explanation:
Given that,
Length of the wire, l = 0.36 m
Speed with which the wire moves in a magnetic field, v = 0.21 m/s
The induced emf produced in the wire is 0.45 volts,
It is a case of motional emf. When a wire moves in a magnetic field with velocity v, an emf is induced in the wire. It is given by :
B is the magnetic field strength
or
So, the magnetic field strength is 6 N/A. Hence, this is the required solution.

The balanced chemical equation representing the process of photosynthesis is:
The reactants in the process of photosynthesis are and H
and the products of the reaction are glucose
and oxygen
. Oxygen is the nonpolar covalent gas which is released in the process of photosynthesis. The reactant
is a nonpolar covalent gas while the other reactant water
has polar covalent O-H bonds.
In the balanced chemical equation, the number of each type of element must be equal on both sides of the reaction.
Answer:
4) Each cytochrome has an iron‑containing heme group that accepts electrons and then donates the electrons to a more electronegative substance.
Explanation:
The cytochromes are <u>proteins that contain heme prosthetic groups</u>. Cytochromes <u>undergo oxidation and reduction through loss or gain of a single electron by the iron atom in the heme of the cytochrome</u>:
The reduced form of ubiquinone (QH₂), an extraordinarily mobile transporter, transfers electrons to cytochrome reductase, a complex that contains cytochromes <em>b</em> and <em>c₁</em>, and a Fe-S center. This second complex reduces cytochrome <em>c</em>, a water-soluble membrane peripheral protein. Cytochrome <em>c</em>, like ubiquinone (Q), is a mobile electron transporter, which is transferred to cytochrome oxidase. This third complex contains the cytochromes <em>a</em>, <em>a₃</em> and two copper ions. Heme iron and a copper ion of this oxidase transfer electrons to O₂, as the last acceptor, to form water.
Each transporter "downstream" is <u>more electronegative</u><u> than its neighbor </u>"upstream"; oxygen is located in the inferior part of the chain. Thus, the <u>electrons fall in an energetic gradient</u> in the electron chain transport to a more stable localization in the <u>electronegative oxygen atom</u>.
