Hii friends !
which conclusion is supported by the data in the table?

a. an increase in the mass of an object causes the same decrease in the gravitational force.

b. an increase in the distance between the objects causes the same decrease in the gravitational force.

c. an increase in the distance between the objects causes a greater change in the gravitational force than the same increase in mass.

d. an increase in the mass causes a greater change in the gravitational force than the same increase in the distance between the objects.

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]
