Answer:
A liquid will flow only sideways and down
Explanation:
Answer:
5.12
Explanation:
5.22 x 10 - 3 = [?] x 10 - 2 (move - 2 to the other side with changed sign)
5.22 x 10 - 3 + 2 = [?] x 10 (divide both sides by 10)
[?] = (5.22 x 10 - 1) / 10
[?] = 5.12
7.5 × 10¹⁹ Electrons flow through a point in a wire in 3.00 s if there is a constant current of i=4.00a.
Q = I × t------------Equation 1
Where Q = charge flowing through the wire, I = current, t = time
Given: I = 4.00 A, t = 3.00 s
Substitute these values into equation 1
Q = 4.00× 3.00
Q = 12.00 C.
But,
1 electron contains 1.6×10⁻¹⁹ C
therefore,
12.00 C = 12.00/1.6×10⁻¹⁹ electrons
= 7.5 × 10¹⁹ Electrons
