Answer : The car’s acceleration is, 2m/s^2

Solution :

Acceleration : It is defined as the change in the velocity of an object with respect to the time.

Formula used :

a=\frac{v_{final}-v_{initial}}{t}

where,

a = acceleration of car = ?

v_{final} = final velocity of car = 40 m/s

v_{initial} = initial velocity of car = 10 m/s

t = time taken = 15 s

Now put all the given values in this formula, we get the acceleration of car.

a=\frac{40m/s-10m/s}{15s}=2m/s^2

Therefore, the acceleration of car is, 2m/s^2

.​Find the pH if the [H3O+1] is 6.2  10-10 M
pishuonlain [190]

Answer:

The pH is 9,21.

Explanation:

The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and higher than 7 to 14 basic. It is calculated as

pH = -log (H 30+)

pH= -log (6,2 x 10^-10)

<em>pH=9,21</em>
