Answer:
Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. The first kind of energy to be recognized was kinetic energy, or energy of motion. In certain particle collisions, called elastic, the sum of the kinetic energy of the particles before collision is equal to the sum of the kinetic energy.
Explanation:
The answer is people debated the ethics of this experiment
Answer:
The correct answer would be - the number of times the student was able to squeeze the clothespin or rate of clothespin squeezing.
Explanation:
The dependent variable is the variable that depends on the change in the independent variable and measured or needs to be found in a scientific experiment or investigation.
In this experiment, the independent variable would be an exercise to found the effect on the change of the rate of clothespin squeezing or the number of times the students are able to squeeze the clothespin.
Thus, the correct answer would be - the rate of clothespin squeezing.
