The true statement according to Newton's laws of motion is; "there is no net force on the block during the 2nd second as zero net force keeps the motion constant."
According to the Newton first law of motion, an object will continue in its state of rest or uniform motion unless it is acted upon by a net force. The action of a net force leads to an acceleration.
In the 2nd second of the journey, there is no net force on the block hence the block continues to move at constant velocity.

Answer:
fem = -0.126 V
Explanation:
Faraday's law is
fem =
where the flow is
Ф = B . A = B A cos θ
bold letters indicate vectors.
In this case, the normal to the area is parallel to the magnetic field, so the angle is zero and the cos0 = 1
fem =
in this case they indicate that to carry the loop from outside to inside the field in Δt = 5 s, so we can change them by variations
fem =
let's calculate
fem = - 0.7 (0.9 -0) / 5
fem = -0.126 V
Answer:
163.5m
this is how far the doggo would go
(In theory)
If I'm wrong I apologize
1. Current means flow of electrons and electrons are negative charged and so are attracted to the positive end of the battery and repelled by the negative end.
2. When battery is connected in a circuit that lets the electron flow through it, they flow from negative to positive.
3. When negative terminal of cell is connected to other negative terminal of the cell in a particular circuit then, current will not flow in circuit as electrons cannot flow from negative to negative terminal.
