Why does doubling the mass of an object double its weight, but doubling its distance
from the center of Earth reduces its weight fourfold? Hint: think of the affects of
gravity and distance
The weight is half the gravitational force between the object and Earth
The weight is equal to the gravitational force between the object and Earth, and the
gravitational force is inversely proportional to the distance squared between the object and
Earth
The weight is directly proportional to the square of the gravitational force between the object
and Earth
The weight is two times the gravitational force between the object and Earth

Homework Origins and How Question Bank Helps
Who Invented Homework?
Homework dates back to the late 19th century, often being credited to an Italian educator named Roberto Nevilis as its creator. Nevilis introduced homework-like assignments as an extra means of reinforcing education outside school hours; although homework-type assignments existed prior to Nevilis. Indeed, ancient civilizations such as Greeks and Romans utilized similar strategies of reinforcing learning outside classroom hours. While Nevilis formalized this practice into homework as we know it today; its meaning has significantly evolved with different cultural and educational influences shaping its current meaning over time.
Does Homework Help Students Learn?
Yes, homework can be a useful tool for reinforcing what children learn in the classroom, but its efficacy is dependent on numerous things. According to research, homework that is purposeful and balanced can help students acquire crucial skills such as time management, critical thinking, and problem solving. However, excessive or badly designed schoolwork can cause stress and exhaustion. Homework works best when it is designed to reinforce key concepts, foster independent thinking, and provide opportunities for personal reflection. So, while homework can be beneficial, the trick is determining the appropriate amount and manner to help pupils learn without overwhelming them.
