Displacement is zero. Displacement is in reference to the starting and ending positions, so starting and ending in the same place would cause a net displacement of zero. Distance, however, is not zero. It is a measurement of the total amount moved, so if the object left the starting position, the distance is automatically not zero.
We are given the resistance and voltage of this lamp and we are asked to find the current; the equation that relates these together is Ohm’s Law, V = IR. Simply plug and solve:
V = IR
(220 V) = I(484 Ohms)
I = 0.4545 Amps
The lamp has a current of 0.4545 Amps passing through it under these conditions.
Hope this helps!
Answer:
C
Explanation:
It is also better so scientists know that the data is accurate and that the results will be reliable. If an investigation is replicable, somebody else can use it. In order for others to achieve the same results scientists also have to be able to collect the same data ...
