Answer:
The ballon has a negative charge. They will attract each other because opposite charges attract. On the other hand, two charged balloons repel each other. Each has a negative charge, and charges that are the same repel one another.

Explanation:
Force may be defined as the cause of motion and deformation. When a force is applied to an object, the object either moves or changes shape or both. In most cases, it is not possible to detect the deformation by naked eyes at the molecular or atomic level. Deformation occurs no matter how small.
For example, a car moving along a straight and horizontal highway, experiences an engine force Fe, while being opposed by an overall frictional force, Ff ( road friction as well as air resistance). If the car is moving to the right and to the right is taken to be the positive direction, then Fe acts to the right and Ff acts to the left. The net force is ΣF = Fe - Ff .
Answer:
The speed of the electron is v = 1.01 x 10¹⁵ m/s
Explanation:
Given data,
The mass of the electron, m = 9.11 x 10⁻³¹ kg
The radius of the circle, r = 2.00 x 10⁻² m
The force acting on electron, F = 4.60 x 10⁻¹⁴ N
The speed of the electron, v = ?
The centripetal force of the electron is given by
F = mv² / r
∴ v² = Fr/m
v =√(Fr/m)
Substituting the given values in the above equation,
v =√( 4.60 x 10⁻¹⁴ x 2.00 x 10⁻² / 9.11 x 10⁻³¹ )
v = 1.01 x 10¹⁵ m/s
Hence, the speed of the electron is v = 1.01 x 10¹⁵ m/s

There are three main factors that affect wave formation: wind velocity, fetch, and duration.
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
