1.
Firstly removing off one strip and it leaves electrons behind, so the strip becomes positively charged.
2. The roll however is not negatively charged because it is "earthed " by the hand holding it, thus excess negatives repel each other away through the hand.
3.Tearing off the next strip and once more it leaves electrons behind, the new strip is also positively charged and will repel the first strip.
4. Then, tear two strips apart and one will leave electrons behind on the other. Meaning that one strip is positive and the other is negative and they will attract each other.

Answer:
fixed cost $231220
Explanation:
given data:
quantity of skl mask = 22,940
skl mass rate = $19 each
variable cost = $6 per unit
therefore
Contribution/unit of ski mask = 19 - 6 = $13
for 22940 ski masks, total cost = (22940*13) = 298220
Depreciation cost $67000
fixed cost is = 298220 - 67000 = $231220
