Answer:
1) Unbalanced
2) Balance
3) Balanced
4) Unbalanced
5) Unbalanced
Explanation:
For 1 and 5, since the objects are not at a constant speed/velocity, their forces must be unbalanced.
For 2 and 3, their speeds are constant so that means the force is balanced. If the bycicle or box started accelerating, that would indicate an unbalanced force
For 4, the speed is constant, but it's direction is not indicating another unbalanced outside force causing it to turn. The force is unbalanced.

Answer:
Explanation:
The probability to find a particle in a 1 dimension box of length is:
Let's recall the wave function of a particle in this candiction will be:
So the propability:
Solving the integral, it is:
We can cancel out <em>a</em> and using n = 10, the probabilty finally will be:
