Answer:
Force's magnitude
Direction: down (towards the center of the Earth)
Explanation:
Recall that the magnetic force on a conductor of length L carrying a current I in a magnetic field B is given by the equation: 
in the case the magnetic field B and the direction of the current are at 90 degrees from each other (which is our case). The direction of the force will be given by the "right hand rule" associated with the vector product that defines this force.
Since the current is moving East, and the magnetic field of the Earth goes from North to South, the resultant Force vector will be pointing towards the Earth (and perpendicular to the plane defined by the current's direction and the magnetic field B)
The magnitude of the force, is given by the formula above, and given that all quantities to be considered are is SI units, it will result in Newtons (N):
Answer:
1.Oxidation - reduction reactions and proton pumping
2. Phosphorylation reactions and proton pumping
Explanation:
In oxidative phosphorylation, electrons are transferred from donors to acceptors, that is redox reaction.
These redox reactions release energy, which is used to form ATP. In eukaryotes, these redox reactions are carried out by protein complexes within cell's mitochondria, whereas, in prokaryotes, these proteins are located in the cells' intermembrane space. These linked sets of proteins are called electron transport chains.
The have the same number of electron shells
Answer:
- 91499.95 V
Explanation:
Let the mid point is P.
qA = 3.4 pC = 3.4 x 10^-12 C
qB = - 6.10 micro Coulomb = - 6.10 x 10^-6 C
AB = 1.20 m
AP = BP = 0.6 m
Let the potential at P due to the charge at A is VA and the potential at P due to the charge at B is VB.
The potential at P is V
V = VA + VB
V = 0.051 - 91500
V = - 91499.95 V
