Answer:
C) upward
Explanation:
The problem can be solved by using the right-hand rule.
First of all, we notice at the location of the negatively charged particle (above the wire), the magnetic field produced by the wire points out of the page (because the current is to the right, so by using the right hand, putting the thumb to the right (as the current) and wrapping the other fingers around it, we see that the direction of the field above the wire is out of the page).
Now we can apply the right hand rule to the charged particle:
- index finger: velocity of the particle, to the right
- middle finger: direction of the magnetic field, out of the page
- thumb: direction of the force, downward --> however, the charge is negative, so we must reverse the direction --> upward
Therefore, the direction of the magnetic force is upward.
Answer:
yes every action as an equal and and opposite reaction. if you throw a tool then it will give you a reaction and you will move back.
Explanation:
According to Newton's third law of motion, when two bodies interact between them, appear equal forces and opposite senses in each of them.
To understand it better:
Each time a body or object exerts a force on a second body or object, it (the second body) will exert a force of equal magnitude but in the opposite direction on the first.
So, if you as an astronaut in the described situation throw your tool in the direction that you are traveling (in the opposite direction of the space station), according to Newton's third law, you will be automatically moving towards the station
Thrust adalah kekuatan atau dorongan. Ketika sistem mendorong atau mempercepat massa dalam satu arah, ada dorong (force) hanya besar dalam arah yang berlawanan. Dalam matematika dan fisika, ini dijelaskan oleh hukum kedua dan ketiga Isaac Newton. Dorong digunakan untuk menggambarkan seberapa baik jenis mesin berjalan. Hal ini dapat digunakan untuk berbagai jenis mesin seperti mesin roket, pesawat (baling-baling) mesin, dan mesin jet.
Thrust diukur dalam "pon dorong" di AS dan di Newton dalam sistem metrik. 4.45 Newton dorong sama dengan 1 pon dorong. Satu pon dorong adalah berapa banyak dorong yang dibutuhkan untuk menjaga satu pon objek tak bergerak melawan gaya gravitasi di bumi.
