if you add a chunk of zinc to a beaker of acid and zinc shavings to another beaker of acid, the sample with the zinc shavings will react faster. what property causes the increase in rate?

i think a, hope it .

explanation:

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
