Answer:
The magnitude of the force on the wire is 2.68 N.
Explanation:
Given that,
Length of the wire, L = 5 m
Magnetic field, B = 0.37 T
Angle between wire and the magnetic field,
Current in the wire, I = 2.9 A
We need to find the magnitude of the force on the wire. The magnetic force in the wire is given by :
So, the magnitude of the force on the wire is 2.68 N. Hence, this is the required solution.
Answer:
Q = A ⊕ B = (A AND B) + ( not(A) AND not(B) )
Explanation:
AND gates : only output 1 when both inputs are 1
OR gate: only output 1 when either or both of the inputs are 1
NOT gates: takes only one input ad output the opposite of the input
The required circuit should takes two inputs and outputs a 1 if and only if the two inputs are the same signal.
The two possible scenarios : both input are 1's or 0's
Q = A ⊕ B = (A AND B) + ( not(A) AND not(B) )
A B not(A) not(B) A AND B not(A) AND not(B) Q
