Displacement is the final position of the object minus the initial position of the object.
Xf - Xi. Displacement is not the distance of the object. If you go to the right 10m and to the left another 10m, your displacement is 0m. But your distance is 20m
Sawmills rely on electricity to run the cutting blade.
Answer:
is the minimum gap between the slabs
Explanation:
Given:
- length of the concrete highway,

- coefficient of thermal expansion,

- range of temperature variation,

<u>Now form the equation of thermal expansion:</u>



Since each slab of the highway expands by the above length so the minimum gap between the slabs to prevent buckling:


is the minimum gap between the slabs
