Marcus is conducting an experiment to investigate the distance an object will move. To do this, he uses a baseball and a bat. He predicts the ball will travel different distances depending on how hard he hits the ball with the bat. Which of the following observations is Marcus most likely to make? The force of motion of the baseball bat was the same for a strong and weak force.

The size of the ball affected the motion, but the size of the force did not affect it.

When a stronger force was applied to the ball, the ball traveled a longer distance.

When a weaker force was applied to the ball, the ball traveled a longer distance.

i am guessing it will be the "When a stronger force was applied to the ball, the ball traveled a longer distance."  but im not entirely sure :)

C

Explanation:

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
