Which scenario is an example of a scientific way of thinking? A. A scientist makes a judgment that rocks are more interesting to
study than living organisms because they tell more about Earth's
history
B. A scientist decides that taking rocks from national parks is wrong
because later park visitors will not be able to see them.
C. A scientist collects different kinds of rocks and then takes them to
museums where the public can appreciate them.
D. A scientist makes a judgment that a rock sample is volcanic
because of the rock's texture and mineral composition,
SON

- measure reactants precisely. ( first choice)

- stir to the reaction take place. ( second choice)

- wait patiently until the reaction completes. ( fourth choice)

- make sure to recover as much copper as possible. ( last choice)

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
