Answer 1
10-2 N

INCORRECT

0.01 newtons is not close to the weight of an apple. This is more lioke the weight of a paperclip.. return to top























Answer 2
100 Newtons

CORRECT

1 newton is closest to the weight of an apple. Gravity times the mass of an apple should equal close to 1 newton. return to top



























Answer 3
102 Newtons

INCORRECT

100 Newtons is the weight of about 10 kg of mass. The mass of an apple is not close to 10 kg. 100N is more like the weight of a car tire. return to top


























Answer 4
104 Newtons

INCORRECT

10,000 Newtons is equal to about 1000 kg. The mass of an apple is not 1000 kg. 10,000 N is more like the weight of a small car. return to top
