Tephra is literally glass. It can be extracted from peat samples by burning off the organic peat. Lapilli is volcanic fragment
A neutral object contains no net charge, but still has many charged particles within the object, it just means that the charges cancel each other out.
Answer:
Explanation:
By definition 
, so we can calculate the total charge that went through the filament since we know the electric current and the time. If the charge of one electron is e, then the total charge will be given by Q=Ne. Combining these equations we get the number of electrons as:
Since the resistivity of tungsten (W) is 
, then resistance can be calculated using the formula:
Where we already obtained the radius from the diameter. Finally the Voltage will be given by the formula:
I think this is about the 5th or 6th time I've seen this question
submitted to Brainly. So far, nobody has yet given us any of
the rest of the question ... the part that tells us something about
the vectors, so that we have some way to know their magnitudes.
So far, nada.
