Answer:
From the given options, the option (D) is correct. Because Al is the aluminium which is located in period 3 of the periodic table.
Explanation:
We know that the 3rd period contains 8 elements which are as follows:
- sodium
- magnesium
- aluminium
- silicon
- phosphorus
- sulfur
- chlorine, and
- argon
The sodium and magnesium, the first 2 elements, are members of the s-block of the periodic table, while the rest of the members are the elements of the p-block.
Thus, from the given options, the option (D) is correct. Because Al is the aluminium which is located in period 3 of the periodic table.
Answer:
current is 4.23 A
Explanation:
Given data
force f1 = 0.030 N
current I = 2.7 A
force f2 = 0.047 N
to find out
the new current
solution
we know that force = flux density(B) × current(I) × length(L) ...............1
f1 = BL × current
so BL = 0.030/ 2.7 = 0.011111
now put BL and f2 in equation 2 we get current
force = flux density(B) × current(I) × length(L)
0.047 = 0.01111 × current
current = 0.047 / 0.01111
current is 4.23 A
