Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that the friction force on two boxes is given as
Now we know by Newton's II law
so we have
Part b)
For block B we know that net force on it will push it forward with same acceleration so we have
Part c)
If Alex push from other side then also the acceleration will be same
So for box B we can say that Net force is given as

Metallic bonds! Hope this helps!! :))
Answer:
the previous correct answer is b
Explanation:
When the circuit is closed in the system, a current is induced that follows the lenz law, which opposes the change that is occurring and therefore the coil increases and the idicidal current in the ring must reach the maximum oppositing is the current of the coil, so quiet force is repulsion
Consequently, the previous correct answer is b
Answer:
α = 1.875 rad/s²
t = 8 s
Explanation:
α = ω²/2θ = 15²/(2(60)) = 1.875 rad/s²
t = ω/a = 15 / 1.875 = 8 s
