What are the Factors that determine resistance value of electrical material?
The factors that determine the resistance value of an electrical material are its length, cross-sectional area, temperature, and resistivity. A longer material will have higher resistance, while a larger cross-sectional area will result in lower resistance. The resistance of a material also changes with temperature, with most materials increasing in resistance as temperature rises. Finally, resistivity is an intrinsic property of the material that determines how strongly it resists the flow of electricity.
On Earth which forces tend to slow an object down?
The main forces that tend to slow an object down on Earth are friction, air resistance, and gravity. Friction occurs when the object moves against a surface, air resistance is the drag force experienced as an object moves through the air, and gravity pulls the object downward.
What force slows objects moving through the air?
Air resistance
What is the sudden movement of electrical charges from one one object to another?
The sudden movement of electrical charges from one object to another is known as an electrical discharge. This can occur due to a build-up of static electricity or during a lightning strike.
What does it mean for an object to have electrical charge?
When an object has electrical charge, it means that it has an imbalance of positive or negative electrons. This imbalance creates an electric field around the object that can interact with other charged objects. Objects with the same charge repel each other, while objects with opposite charges attract each other.
Which one of the following does not affect the electrical resistance of a body?
The color of the body does not affect its electrical resistance. Electrical resistance is determined by factors such as the material, dimensions, and temperature of the body. The color of an object is related to its appearance and does not have a direct impact on its electrical properties.
What do you understand by term resistance?
The electrical resistance of an object is a measure of its opposition to the passage of a steady electric current. An object of uniform cross section will have a resistance proportional to its length and inversely proportional to its cross-sectional area, and proportional to the resistivity of the material.Discovered by Georg Ohm in the late 1820s,[1] electrical resistance shares some conceptual parallels with the mechanical notion of friction. The SI unit of electrical resistance is the ohm, symbol Ω. Resistance's reciprocal quantity is electrical conductance measured in siemens, symbol S.
What three factors affect how much electrical resistance an object has?
Any load would do or anything that has resistance. Which is pretty much everything you can hook up to a circuit. For example, lightbulb, buzzer, resistor etc.
How does air resistance affect the acceleration of a falling object-How does air resistance affect the acceleration of a falling object?
It reduces the acceleration of the falling object due to friction.
What freature of an object does not affect air resistance?
The internal composition or material of an object does not affect air resistance. Air resistance is mainly determined by an object's size, shape, and speed when moving through air.
What feature characteristic of an object does not affect air resistance?
The feature characteristic of an object that does not affect air resistance is the object's mass. Air resistance is determined by the object's shape, size, and speed through the air, but not its mass.
What variables can affect an object floating?
Air Resistance
What are the factors that affect the speed of an object in free fall with air resistance?
The factors that affect the speed of an object in free fall with air resistance are the object's mass, the surface area of the object, the density of the air, and the gravitational force acting on the object.
What resistance to the motion of an object?
Inertia.
What are the Factors that determine resistance value of electrical material?
The factors that determine the resistance value of an electrical material are its length, cross-sectional area, temperature, and resistivity.

The resistance of a material also changes with temperature, with most materials increasing in resistance as temperature rises. Finally, resistivity is an intrinsic property of the material that determines how strongly it resists the flow of electricity.
What is the correct definition of resistance?
Resistance refers to the opposition a material or object offers to the flow of electric current. It is measured in ohms and is influenced by factors like material composition, length, and cross-sectional area. Resistance is a key property in determining the behavior of electrical circuits.
What three variables affect peripheral resistance to blood flow?
Resistance is determined by three properties: the lengthand cross-sectional area of a material, and its resistivity. Since resistivity is affected by temperature, you could say that temperature indirectly affects resistance.
