Help please K12 Mechanical Energy Quiz! Which statement is true regarding the ping-pong ball at the bottom of the ramp in the experiment, “Rolling Along”?

Question 1 options:

A. No energy was involved in this experiment.

B. Only potential energy from the ball coming down the ramp will be given to the ping-pong ball at the bottom of the ramp.

C. The kinetic energy of the ball coming down the ramp will be given to the ping-pong ball at the bottom of the ramp.

D. All kinetic energy remains with the ball that is coming down the ramp- none of it transfers to the ping-pong ball at the bottom.

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.

Acm ruler with main graduations from 1 to 10 from left to right there are 10 secondary graduations between each of the main graduations there is a line that begins. at the left end of the ruler 10 secondary graduations to the left of the “1 main graduation the right end of the line ends on the eighth secondary graduation to the right of 3 how long is the line
