Answer:
<h3>a stationary electric charge, typically produced by friction, which causes sparks or crackling or the attraction of dust or hair.Static electricity has several uses, also called applications, in the real world. One main use is in printers and photocopiers where static electric charges attract the ink, or toner, to the paper. Other uses include paint sprayers, air filters, and dust removal. Static electricity can also cause damage.Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge.</h3>
Answer:
b) a compound which produces ions dissolved in a solution that conduct electricity.
NaCl is an electrolyte.
Answer:Temperature is a measure of average kinetic energy of particles in an object.
Explanation:
The hotter the substance, higher is the average kinetic energy of its constituent particles. When we heat a substance, the particles that constitute the substance gain some energy and begin to move faster.
The amount of force exerted is 77.7N
<u>Explanation:</u>
Given:
Work done, W = 350J
Distance, x = 4.5m
Force, F = ?
We know,
Work = force X distance
350 = F X 4.5m
F = 77.7N
Therefore, the amount of force exerted is 77.7N
