Electrons move from the sweater to the balloon. The sweater becomes positively charged, while the balloon becomes negatively charged.
Explanation:
- Sweater is a conductive material, which means it readily gives away its electrons.
- Consequently, when you rub a balloon on Sweater, this causes the electrons to move from the Sweater to the balloon's surface.
- The rubbed part of the balloon now acquired a negative charge. Objects made of rubber, such as the balloon, are basically electrical insulators, meaning that they resist electric charges flowing through them.
- This is why only part of the balloon may have a negative charge (where the wool rubbed it) and the rest may remain neutral after electrostatic process.
If the mass of an object doubles, the weight of the object also doubles
If the mass of an object halves, the weight of the object also halves
Explanation:
The mass of an object is an intrinsec property of the object that gives a measure of the "amount of matter" in the object. Mass is indipendent from the location of the object.
On the contrary, weight gives a measure of the force of gravitational attraction felt by the object in a gravitational field. Weight is dependent on the location.
The mass and the weight of an object are related by the following equation:

where:
W is the weight of the object
m is its mass
g is the acceleration of gravity
We see from the formula that the weight of an object is directly proportional to its mass. This means the following:
- If the mass of an object doubles, the weight of the object also doubles
- If the mass of an object halves, the weight of the object also halves

Answer:
Aristotle was blind, therefore could not see change in positions. Aristotle could see no detectable change in the positions of the stars, thought Earth was immovable.
