It took Mason 9.4 - 2.65 = 6.75 minutes to complete the Second Challenge.
Answer:
The answer is the option D
Step-by-step explanation:
we know that
In a right triangle
Applying the Pythagoras Theorem
where
c is the hypotenuse
a and b are the legs
In this problem we have
substitute and solve for b
It's 5 because the fraction when you divide. 23.
Induced emf = -NA (ΔФ/Δt)
N = 1 (assuming its 1 loop), ΔФ = 0.2-0 = 0.2 T, Δt = 0.3 sec, A = 0.12 m^2
Therefore,
Induced emf = -1*0.12*(0.2/0.3) = -0.08 V
