The gravitational pull between two objects depends on their mass and distance. What is meant by distance?(1 point)
How close the two objects are located, meaning that closer objects have a stronger gravitational pull than objects farther apart.
How close the two objects are located, meaning that closer objects have a stronger gravitational pull than objects farther apart.
The height of an object above the ground, meaning that an object will fall faster as the height above the ground increases.
The height of an object above the ground, meaning that an object will fall faster as the height above the ground increases.
The length of the object, meaning if the object is longer it will exhibit more gravitational pull than if it is short.

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
