For a projectile launched horizontally, which of the following best describes the downward component of a projectile's velocity? assume air resistance is negligible. a. the downward component of the projectile's velocity is zero. b. the downward component of the projectile's velocity remains a nonzero constant. c. the downward component of the projectile's velocity continually increases. d. the downward component of the projectile's velocity continually decreases. e. the downward component of the projectile's velocity initially decreases and then increases.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

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!
