Answer:
Identify the object to be analyzed. For some systems in equilibrium, it may be necessary to consider more than one object. Identify all forces acting on the object. Identify the questions you need to answer. Identify the information given in the problem. In realistic problems, some key information may be implicit in the situation rather than provided explicitly.

The maximum acceleration the truck can have so that the refrigerator does not tip over is 4.15 m/s².
<h3>What will be the maximum acceleration of the truck to avoid tipping over?</h3>
The maximum acceleration is obtained by taking clockwise moments about the tipping point of rotation.
Clockwise moment = Anticlockwise moment
Ft * 1.58 m = F * 0.67 m
where
- Ft is tipping force = mass * acceleration, a
- F is weight = mass * acceleration due to gravity, g
m * a * 1.58 = m * 9.81 * 0.67
a = 4.15 m/s²
The maximum acceleration the truck can have so that the refrigerator does not tip over is 4.15 m/s².
In conclusion, the acceleration of the truck is found by taking moments about the tipping point.

The wavelengths of the constituent travelling waves CANNOT be 400 cm.
The given parameters:
- <em>Length of the string, L = 100 cm</em>
<em />
The wavelengths of the constituent travelling waves is calculated as follows;
![L = \frac{n \lambda}{2} \\\\n\lambda = 2L\\\\\lambda = \frac{2L}{n}](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7Bn%20%5Clambda%7D%7B2%7D%20%5C%5C%5C%5Cn%5Clambda%20%3D%202L%5C%5C%5C%5C%5Clambda%20%3D%20%5Cfrac%7B2L%7D%7Bn%7D)
for first mode: n = 1
![\lambda = \frac{2\times 100 \ cm}{1} \\\\\lambda = 200 \ cm](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7B2%5Ctimes%20100%20%5C%20cm%7D%7B1%7D%20%5C%5C%5C%5C%5Clambda%20%3D%20200%20%5C%20cm)
for second mode: n = 2
![\lambda = \frac{2L}{2} = L = 100 \ cm](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7B2L%7D%7B2%7D%20%3D%20L%20%3D%20100%20%5C%20cm)
For the third mode: n = 3
![\lambda = \frac{2L}{3} \\\\\lambda = \frac{2 \times 100}{3} = 67 \ cm](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7B2L%7D%7B3%7D%20%5C%5C%5C%5C%5Clambda%20%3D%20%5Cfrac%7B2%20%5Ctimes%20100%7D%7B3%7D%20%3D%2067%20%5C%20cm)
For fourth mode: n = 4
![\lambda = \frac{2L}{4} \\\\\lambda = \frac{2 \times 100}{4} = 50 \ cm](https://tex.z-dn.net/?f=%5Clambda%20%3D%20%5Cfrac%7B2L%7D%7B4%7D%20%5C%5C%5C%5C%5Clambda%20%3D%20%5Cfrac%7B2%20%5Ctimes%20100%7D%7B4%7D%20%3D%2050%20%20%5C%20cm)
Thus, we can conclude that, the wavelengths of the constituent travelling waves CANNOT be 400 cm.

Answer:
forces that are equal in size and opposite in direction. Balanced forces do not result in any change in motion. unbalanced. forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion.
