The charge on the droplet must be 
Explanation:
In order for the oil droplet to be in equilibrium, the force of gravity acting on it (the weight, acting downward) must be equal to the electrical force acting upward.
The gravitational force is:
which is equivalent to the weight of the droplet.
The electric force is given by:
where
q is the charge on the oil droplet
is the magnitude of the electric field
Since the two forces must be equal,
And solving for q,

The answer is convection. There are three main types of heat transfer: conduction, convection, and radiation. Among the three, convection is the one that involves heat transfer through a flowing material or medium. Conduction involves the direct contact between two surfaces at different temperatures, while radiation involves heat transfer through electromagnetic waves.
Answer:
Types of Mechanical Energy
There are two types of energy: potential and kinetic.
Potential energy is energy that is stored in an object due to its position. This type of energy is not in use but is available to do work. For example, the book possesses potential energy when it is stationary on the top of the bookshelf.
Ep=m*g*h (m - mass, g - gravitaional acceleration (Earth mean value g=9, 81 m/(s2), h - height from the zero or referent level) s2=s*s
Kinetic energy is energy that is possessed by an object due to its motion. For example, if the book were to fall off the shelf, it would possess kinetic energy as it fell. All energy is either potential or kinetic.
Ek=(m*v2)/2 v2=v*v
The law of the conservation of energy states that energy is neither created nor destroyed. Instead, it is simply transferred from one type of energy to another, or from one form of energy to another. The difference between mechanical energy and kinetic energy is that kinetic energy is a type of energy, while mechanical energy is a form of energy.
Answer:
you can find your own happiness by being different. Standing out. Everyone is a follower these days, so maybe by making your own decisions without influence from anybody. Idk, I tried.
