A=dv/ dt
a=(v2-v1)/(t2-t1)
a=(60-50)/(10-0)
a=10/10
a=1
it's acceleration is 1 km/s^(2) or 1000 m/s^(2)
Hope I can help u

False. A buffering solution consists of a WEAK acid such as CH3COOH, C5H5N, or ammonia. <span>A buffering solution resists pH change upon the addition of an acidic or basic components. It can neutralize little amounts of added acid or base, thus maintaining the pH of the solution relatively stable. The correct answer is letter "B. false"</span>
