The correct response is:
**The balloons will push away from each other.**
Since both balloons are negatively charged, they will repel each other due to the electrostatic force between like charges.

The correct response is:
**Magnetic**
An electrical current produces a magnetic field, which is the basis for the operation of many electrical devices, such as motors and generators.

The correct response is:
**The force of gravity would double.**
The force of gravity between two objects is described by Newton's law of universal gravitation, which states that the gravitational force is directly proportional to the product of the masses of the two objects. If the mass of the Earth doubles, the gravitational force between the Earth and the Sun would also double.

The correct response is:
**The balloon’s charge became negative, and the hair’s charge became positive.**
When the balloon is rubbed against the hair, electrons are transferred from the hair to the balloon. This causes the balloon to gain a negative charge (due to the excess electrons) and the hair to lose electrons, resulting in a positive charge.

The correct response is:
**Evenly distributed on the ball’s surface.**
When a negatively charged plastic rod comes into contact with a conductive object like a rubber ball, the negative charges will distribute themselves evenly across the surface of the ball. This is due to the repulsion between like charges.

The correct response is:
**From the left to the right of the cans.**
When the negatively charged balloon is brought near the can on the left, it will repel the negatively charged electrons within the soda cans. This repulsion causes the electrons in the left can to move away from the balloon, resulting in a net positive charge on the left can and a net negative charge on the right can, causing the negatively charged atoms to move from left to right.
