Answer:
The magnitude of the magnetic force acting on the wire is zero, because the magnetic field is parallel to the wire.
In fact, the magnetic force exerted by the magnetic field on the wire is
where I is the current in the wire, L the length of the wire, B the magnetic field intensity and the angle between the direction of B and the wire. In our problem, B and the wire are parallel, so the angle is and so , therefore the magnetic force is zero: F=0.
Answer:
The cooling time will not be reduced.
Explanation:
The time to cook is virtually the same in both types, vigorously and gently boiling water.
The reason cooking of spaghetti calls for vigorously boiling water is to keep the pasta agitated so that they do not stick to one another.
The temperature of boiling water is the same for both vigorously boiling water and gently boiling water, therefore there will be little time difference in when the potatoes will cook when it is done with vigorously boiling water than when it is cooked with gently boiling water.
However cooking potatoes in vigorously boiling water may cause the water to dry up on time and the potatoes get burnt.

<h2>Energy remains constant </h2>
Explanation:
Thermodynamic Laws -
- The primary law, otherwise called the Law of Conservation of Energy, expresses that energy remains constant in the overall reaction, it is not created or destroyed.
- The second law of thermodynamics expresses that the entropy increases. after the completion of the reaction of any isolated system
- The third law of thermodynamics expresses that as the temperature reaches towards an absolute zero point the entropy of a system becomes constant.
Standard Electronic potential -
- The standard reduction potential may be defined as the tendency of a chemical species or the reactants to get into its reduced form after the overall reaction.
- It is estimated at volts.
- The more is the positive potential the more is the reduction of the chemical species
Aerobic grow is much more efficient at making ATP because of the presence of oxygen the cycles in the respiration are carried out at an efficient rate which forces the cell to undergo a much large amount of ATP production.
