Answer:
![2.4 m/s^2](https://tex.z-dn.net/?f=2.4%20m%2Fs%5E2)
Downward
Explanation:
We are given that
Mass of monkey=12.8 kg
Tension=156 N
We have to find the magnitude of the elevator's minimum acceleration.
![T=m(g+a)](https://tex.z-dn.net/?f=T%3Dm%28g%2Ba%29)
Where ![g=9.8 m/s^2](https://tex.z-dn.net/?f=g%3D9.8%20m%2Fs%5E2)
Substitute the values
![156=12.8(a+9.8)](https://tex.z-dn.net/?f=156%3D12.8%28a%2B9.8%29)
![9.8+a=\frac{156}{12.8}=12.2](https://tex.z-dn.net/?f=9.8%2Ba%3D%5Cfrac%7B156%7D%7B12.8%7D%3D12.2%20)
![a=12.2-9.8=2.4 m/s^2](https://tex.z-dn.net/?f=a%3D12.2-9.8%3D2.4%20m%2Fs%5E2)
Hence, the acceleration =![a=2.4 m/s^2](https://tex.z-dn.net/?f=a%3D2.4%20m%2Fs%5E2)
Direction of the elevator's minimum acceleration is downward because the elevator moves downwards.

Answer:
true
Explanation:
ionic compounds do not form molecules
The displacement covered by the worker in the whole trip is 30km.
The easiest way to solve this problem is using the displacement equation:
Δx = x₂ - x₁
A worker covers a distance of 40 km from his house to his place of
work, and 10 km towards his house back. So:
Δx = x₂ - x₁ = 40km - 10km = 30km
