Two locomotives approach each other on parallel track. Each has speed of 95 km/h with respect to the ground. If they are initially 8.5 km apart. How long will it take before they reach each other?

It will take 2.68 minutes for them to reach each other.

Explanation:

We use the two following kinematic equations, making the final position the same (for the moment they meet each other):

locomotive 1 -->  

locomotive 2 -->  

we make the two xf equal, and solve for the time (t) using v = 95 km/h:

converting the hours into minutes by multiplying this value times 60;

t = 2.68 minutes

this means that the temperature of both substances will be equal

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
