Answer:
the sign of these carriers is POSITIVE
Explanation:
In the effect, he found the charge carriers that were subjected to two forces, one electric and the other magnetic.
F = F_e + F_m = q E + q v x B
bold indicates vectors
The electric field goes to the east, therefore the current also has this direction, the vector product of the velocity of the charge carriers towards the east and the magnetic field upwards, using the right hand rule a magnetic force is created towards the north if the carriers are positive.
In the exercise they indicate that the north side has a higher potential than the south side, therefore there must be an accumulation of carriers on this side that create an electric field (Hall) that is put to the magnetic force until reaching equilibrium when the total force is zero.
Therefore the sign of these carriers is POSITIVE
That would be newton's. You'll be studying or have studied about newton's laws of physics. Both will help you. Hope this helps!
Answer:
See the explanation below
Explanation:
Many of the advantages are due to higher power generation efficiency compared to other forms of power generation.
For example, a smaller amount of uranium compared to carbon or oil is needed to produce the same amount of energy.
Nuclear power plants can be installed in isolated and safe places far from the cities and not necessarily near a river, as if it happens in hydroelectric plants.
A nuclear power plant can supply power to large metropolises, ensuring a level of reliability of 98%, compared to thermoelectric and hydroelectric power plants.
Its working fuel is uranium or plutonium, energy that is used to heat bars that are immersed in water generating steam. The amount used of radioactive material (uranium or plutonium) is very small compared to fossil fuels such as coal and oil.

your all problems will be solved.
in this case the answer is 5 km per hr</span>
Answer:
Newton's 3rd law of motion
Explanation:
According to the question, Newt noticed that It hurt his body more when he Jumped off a high diving board than It did when he Jumped off the lower board. What law of newton is this and why
By the time Newt want to jump, for him to do so, he has to push himself against the ground according to the Newton's 3rd law of motion.
The law states that in every action, there will be equal and opposite reaction.
The force at which he pushes himself against the ground will determine the force at which he will carry himself to jump off the high diving board.
The reaction towards the high diving board will be greater than the reaction towards the low diving board.
Therefore, Newt will hurt his body more when he Jumped off a high diving board than It did when he Jumped off the lower board. And the law of newton that is responsible for this is Newton's third law of motion.
