Answer:
No.
Explanation:
- According to Faraday's law, the induced emf in the circuit is given by :
, it is proportional to the rate of change of magnetic flux.
- In this case, a short piece of wire that is not attached to anything and move it up and down in a magnetic field. It means that the circuit is not completed here. It is an open circuit. For the induction of current, a circuit must be completed.
- Hence, no current will induce.
I think the correct answer from the choices listed above is the third option. The magnetic quantum number of an electron (m) designates the orientation in space of the orbital (electron cloud). <span>This number divides the subshell into individual orbitals which hold the electrons; there are 2l+1 orbitals in each subshell. </span>

Answer:
4.0 m/s²
Explanation:
Draw two free body diagrams, one for the cart and one for the hanging mass.
The cart has one force acting on it in the x direction: tension to the right.
The hanging mass has two forces acting on it in the y direction: tension up and weight down.
The hanging mass accelerates downward, so if we take up to be positive, then the acceleration is negative.
Apply Newton's second law to the hanging mass:
∑F = ma
T − m₂g = m₂(-a)
T − m₂g = -m₂a
Apply Newton's second law to the cart:
∑F = ma
T = m₁a
Substitute and solve for a:
m₁a − m₂g = -m₂a
m₁a + m₂a = m₂g
(m₁ + m₂) a = m₂g
a = m₂g / (m₁ + m₂)
Given m₁ = 2.3 kg and m₂ = 1.6 kg:
a = (1.6 kg × 9.8 m/s²) / (2.3 kg + 1.6 kg)
a = 4.0 m/s²
