Static electricity is caused by the build up of charges on surfaces of objects while electric current is the constant flow of electrons along a conductor (the rate of flow of charge).

The question is missing its alternative. Here is the complete question.

Which best describes a difference between electric current and static electricity?

a. Electric current is continuous and static electricity is not continuous.

b. Static electricity is continuous and electric current is not continuous.

c. Electric current involves the movement of electrons, and stattic electricity involves the moment of protons.

d. Static electricity involves the movement of electrons and electric current involves the movement of protons.

Answer: a. Electric current is continuous and static electricity is not continuous.

Explanation: <em>Electric current</em> occurs when there is a flow of electrons (negative charges) in a circuit or conductor. The flow happens when there is a difference of potential between the ends of a circuit. The flow of electrons is non-stop so, electric current is continuous.

<em>Static electricity</em> is due to an imbalance of electric negative charges within or on an object's surface. This imbalance most likely happens by friction and consists of motionless isolated charges. For that reason, static electricity is not continuous.

How does friction make it possible for you to walk across the floor?

Tema [17]

if we are walking on a perfectly smooth ground which has no friction our force would simply cancel out the force reverted by the ground and we would fall.

We need it to help push out feet off the ground

Hope those helps :)

Calculate the maximal friction force for a parked car between the rubber tires and a wet street. Assume the car’s mass is 1600 k

NikAS [45]

Answer:

$Fr=12544N$

Explanation:

1. Find the equation of eht maximal friction force:

The maximal friction force is given by the equation $Fr=usmg$ , where μs is the static friction coefficient, m is the car´s mass and g is the gravitational force.
