An object on earth has a mass of 4 kg. calculate its weight on another planet that has an acceleration due to gravity one-half that of the earth.

Relatively the same work as what Al2006 did, just round off the answer to 20 N.

So,

w₂ = 19.6 ≈ 20 N

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

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!
