When a person touches an uncharged object, the transfer of electrons between the person and the object can cause a build-up of static electricity. When the charge difference becomes great enough, a spark can occur as the excess charge jumps the gap between the person and the object, equalizing the charge.
What else can I help you with?
Why does a spark occur when a person who is charged touches an uncharged object?
Near the charged object, there is a high charge, near the uncharged object a low charge. As you bring them together the gradient between the two gets steeper and steeper until it is strong enough to pull electrons away from the atoms in the air, ionizing it. The ionized air conducts electricity better, making the gradient steeper still, and a chain reaction occurs. The energy stored is released in a sudden discharge, causing the heat, light and sound of the spark. Lightning follows the same principle.
What rearrangement of electrons on an uncharged object without direct contact without a charged object?
The rearrangement of electrons on an uncharged object without direct contact with a charged object can occur through induction. This process involves bringing a charged object near the uncharged object, which causes a temporary separation of charge within the uncharged object. The closer charged object induces a redistribution of electrons within the uncharged object, resulting in one side becoming more negatively charged while the other becomes more positively charged.
The change of the velocity of an object divided by the time for the change to occur?
That's a pretty good definition of the object's "acceleration".
What changes occur to an object when force is applied on it?
When a force is applied to an object, it can cause the object to accelerate, move, deform, or change its shape. The specific changes that occur depend on factors such as the magnitude and direction of the force, as well as the properties of the object, such as its mass or elasticity.
When you do positive work on an object, what changes occur in the object as a result of your efforts?
When you do positive work on an object, the object's energy increases and its motion or position may change as a result of your efforts.

What are Crush wounds?
They occur when a heavy object falls onto a person, splitting the skin and shattering or tearing underlying structures
What is a noun form?
Where it changes a word into a noun which is the form and the something for example, occur. The noun form of occur is occurrence so it's changing the verb into a noun - person, place and object.
When does resonance occurs?
Resonance can occur when an object vibrates at another objects resonant frequency.
How do shadows occur?
by an object blocking light
What is dependencies in database?
Referentail dependencies occur when an object is referenced in the definition of another object

Occur when a vehicle hits another object?
collision
Where is the force out with no runners on base?
In baseball, a force out can occur when there are no runners on base if a fielder touches the base before the batter-runner reaches it.
What is needed to to facilitate diffusion and active transport?
ATP is needed for these two transport mechanisms to occur.
