Elena makes a table to organize the functions of electric motor components. which functions belong in the cells marked x and y? component function brush x commutator y a. x: conducts current to the armature and reverses direction of current y: rotates as a result of changing magnetic forces b. x: rotates as a result of changing magnetic forces y: conducts current to the armature and reverses direction of current c. x: allows current to flow into the commutator y: conducts current to the armature and reverses direction of current d. x: allows current to flow into the commutator y: rotates as a result of changing magnetic forces

C. X: Allows current to flow into the commutator

Y: Conducts current to the armature and reverses direction of current

Explanation:

Carbon brush is a motor brush that acts as the conducting block  for current between the stator and the rotor of a motor.It is made of carbon blocks.The brush is held in place using a spring that ensures its contact position with the commutator.The commutator prevents the torque on the motor from reversing whenever the coil is rotating in the magnetic field.

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.  

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
