Read these sentences from paragraph 1: in every dark hour of our national life, a leadership of frankness and vigor has met with that understanding and support of the people themselves which is essential to victory. i am convinced that you will again give that support to leadership in these critical days. why does president roosevelt include these sentences in his speech? question 24 options: a) to reaffirm the public’s fear of a perilous future in which they will all suffer material and financial loss. b) to support the idea that he cannot do anything to the situation. c) to illustrate to the sheer might and power of the united states government. d) to reassure the country of his credibility and emphasize the importance of standing united behind the government.

i don't know that i agree with that but what's the question ?

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.
