D. All of the above.
These are all places you could get information from, therefore making them all sources.
Answer:
They could lose their magnetism if they are dropped too hard or banging against something (the ground)
Explanation:
the domains may bump out of alignment. hope this helps ! :)
Answer:
Complete the following table. Be sure to include units in your answer.
Explanation:
all you have to do is mautiply them
Explanation:
a) The height of the ball h with respect to the reference line is
so its initial gravitational potential energy 
is
b) To find the speed of the ball at the reference point, let's use the conservation law of energy:
We know that the initial kinetic energy 
as well as its final gravitational potential energy 
are zero so we can write the conservation law as
Note that the mass gets cancelled out and then we solve for the velocity v as
Answer:
3V
Explanation:
From the question given above, we can see clearly that the resistors are arranged in parallel connection. Hence, the same voltage will pass through the resistors i.e
Total voltage = voltage of 3 Ω = voltage of 6 Ω
From the question given above,
The total voltage = 3 V
Therefore,
Voltage of 3 Ω = total voltage
Voltage of 3 Ω = 3V
Thus, option 3 gives the correct answer to the question.
