1. Determine which of the following statements are true about momentum. a. Momentum is a vector quantity.
b. The standard unit on momentum is the Joule.
.C. An object with mass will have momentum.
d. An object which is moving at a constant speed has momentum.
.e. An object can be traveling eastward and slowing down; its momentum is westward.
f. Momentum is a conserved quantity; the momentum of an object is never changed.
•g. The momentum of an object varies directly with the speed of the object.
.h. Two objects of different mass are moving at the same speed; the more massive object will have the greatest
momentum
i. A less massive object can never have more momentum than a more massive object.
•j. Two identical objects are moving in opposite directions at the same speed. The forward moving object will have
the greatest momentum.
k. An object with a changing speed will have a changing momentum.
.

spare some change and give it to the poor

explanation:

plz : ((

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.
