Answer:
True.
Explanation:
According to Lenz's law, the induced current in a circuit always flows to oppose the external magnetic field through the circuit. This statement is true.
The Faraday's law of induction is given by :
Here, negative sign shows that the direction of induced emf is such that opposes the changing current that is its cause.
Hence, the statement is true.
Therefore, elements whose atoms can have the same number of valence electrons are grouped together in the periodic table of the elements. As a general rule, a main group element (except hydrogen or helium) tends to react to form a closed shell, corresponding to the electron configuration s2p6.

Answer:
d. 32.0 rad
Explanation:
The angular speed, denoted by ω can be calculated thus;
ω = θ /t
Where;
ω = angular speed in radians/sec
θ = angle in radians
t = time in seconds
∆ω = final ω - initial ω
ω = 12.00 rad/s - 4.00 rad/s
ω = 8.00 rad/s
Hence, using ω = θ/t
8.00 = θ/4
θ = 32.00rad
