Answer:
The atoms are aligned in a particular direction
Explanation:
The atoms become aligned in a particular direction in regions called domains, thus resulting in an overall resultant magnetism due to the spin of the electrons.
Answer:
Explanation:
The 2 equations we need here are, first:
and then once we solve for the acceleration here:
Δx
Solving for acceleration:
and now we will use that in the other equation:
Δx and
36 = 16 + 
Δx and
20 = Δx and
Δx so
Δx = 50 m
Answer: Capacitor
Explanation: A capacitor stores energy as charge in an electrical field between two conducting plates called electrodes which allows the flow of electrons between them.
Answer: 26.6 J
Explanation:
The heat needed to raise the temperature of a solid body, using only a conductive process, has been empirically showed to be equal to the following expression:
Q= c . m. (t2 – t1)
where c= specific heat capacity (in J/gK), m= mass of the solid (in g) ,
and (t2 - t1)= difference between final and initial temperatures.
Replacing by the values, we get:
Q= 0.385 J/gK . 1,550 g. (77.5ºC – 33.0ºC)= 26.6 J
