Students learned that objects can exert forces on other objects without touching. Which three investigations will provide evidence what they have learned. a measuring how close a soda can must be before it rolls toward a balloon that has been rubbed

Yes she is correct. the answer is completely correct

Woah that’s a lot to read xd i’ll try though. i’ll get back t you if. i know the andwer

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.
