Which of these is not an example of how the use of resources has changed? car companies have developed hybrid cars. cars still largely rely on oil. more wind farms are present in the united states. more products are made from recycled materials.

Your answer should be B.) Cars still largely rely on oil. This is because it shows no sign of a change of using our resources as we have almost always used oil.

Hybrid Cars show that we are adapting to our resources and allows cars to rely less on oil

Wind power allows as a substitution for resources like Coal and Oil

Products are being made from Recyclables (used items), instead of other resources

This clearly shows that the answer should be B.) Cars still largely rely on oil.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
