Answer:
0.82 m/s^2
Step-by-step explanation:
Given data
initial velocity=20m/s
Final velocity= 30m/s
Time = 12.2s
Applying the formula
a= v-u/t
a= 30-20/12.2
a= 10/12.2
a= 0.819
a=0.82 m/s^2

Step-by-step explanation:
Answer: [H+] = 10^-7.2
Step-by-step explanation:
Given that the PH of the solution = 7.2
Using the formula pH = –log[H+]. To get the H+ concentration from the pH, raise both sides by the base of 10. Then we have
10^ -pH = H+. with pH of 7.2,
Thus the answer to this problem is
[H+] = 10^-7.2
