Answer:
Sources of electrical current
Step-by-step explanation:
Based on the information given the reason why
He/ She places a compass at different positions on a wall until the compass needle change to a direction was because the construction worker
was most likely using the compass to find the Sources of an ELECTRICAL CURRENT or where the ELECTRICAL CURRENT originated from reason been that ELECTRICAL CURRENT is the movement of electric charge from cathode to anode .
Answer:
12.05
Reason:
8.6
+3.45

12.05
Don’t forget to carry the one to the left
6+4= 10 carry the one to the left.
8+3+1 = 8+4 =12
Answer 12.05
n(A-B) denotes elements which are in A but not in B
n(Au B) denotes elements in A and B
n(AnB) denotes elements that are common in A and B
Now I will add one more set
n(B-A) which denotes elements in B but not in A
So, n(AuB) = n(A-B) + n( B-A) +n(AnB)
70 = 18 +n(B-A) + 25
70 = 43 + n(B-A)
n(B-A) = 70-43
n(B-A) = 27
So, n(B) = n( B-A) + n( AnB)
= 27+25
= 52
