Yes, a doorknob is typically made of metal, which is a good conductor of heat. This means that it can transfer heat from one object to another, such as when you touch a hot doorknob and feel the heat from the other side.
Cotton string is an insulator, meaning it does not conduct electricity well. Its properties make it suitable for use in applications where electrical conductivity is not desired.
To find the mass of an object, you can use a balance or a scale. Place the object on the balance or scale, and it will give you a measurement of the object's mass.
You would not use the object's mass to find its acceleration. Acceleration is determined by the force acting on an object, as given by Newton's second law of motion (F = ma), not by the object's mass alone.
You can use science texts to represent forces of an object by describing the magnitude, direction, and type of force acting on the object. For example, you can explain the gravitational force pulling an object downwards with a specific value in newtons, or describe the contact force exerted by a surface on the object in a given direction. Use relevant equations or diagrams to support your explanations.
An electrical charge is attracted to a conducter (ie a material which conducts such as copper) therefore you can either use something more conductive leading away, or insulate the object.
a good conducter of electricity needs what object to work
