It is given to us that the velocity of an object in meters per second varies directly with time in seconds since the object was dropped, as represented by the table (which is not given to us). The acceleration due to gravity is the constant of variation. Now, we know, from basic physics that the value of the acceleration due to gravity in the SI unit is 9.8 m/s^2. Therefore, the second option is the correct option. 
11/12 because 1/6= 2/12 and 3/4= 9/12 and when u add them u get 11/12
To do this first add the sunny days and rainy days together.
6+7= 13
now subtract the number of cloudy days from 13
13-4= 9
Hope this helped :)
The answer is 2............
