A train is accelerating at a rate of 2 m/s. If its intital velocity is 20 m/s, what is its veolcity after 30 seconds

80 m/s.

Explanation:

NOTE: This is a physics question. However, the solution to the question given below:

From the question given above, the following data were obtained:

Acceleration (a) = 2 m/s²

Initial velocity (u) = 20 m/s

Time (t) = 30 s

Final velocity (v) =?

The final velocity of the train can be obtained as shown below:

v = u + at

v = 20 + (2 × 30)

v = 20 + 60

v = 80 m/s

Therefore, the final velocity of train is 80 m/s.

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.
