What is the force of gravitational attraction between an object with a mass of 2kg and another that has a mass of 2kg and a distance between them of 2.5 m

Explanation:

F = 0.000000000042716 or 4.2688e-11

G = 6.67 × 10−11 Nm2 /kg2

m1 = 2kg

m2 = 2kg

R = 2.5 m ⇒ R^2 = 6.25

F =  6.67 × 10^−11 ( 2 * 2) / 6.25

⇒ F = 6.67 × 10^−11 (4) / 6.25

⇒ F = 2.668e-10 / 6.25

∴ F = 4.2688e-11

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
