Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
When the length and area of cross-section both are doubled then its resistance?
The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.

The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
What is the volume of a 30 pipe?
It depends on what you mean by a 30 pipe. Is 30 the cross sectional area - in which case, what is the length of the pipe? Is 30 the length - in which case, what is the cross-sectional area?
What is the formulla of determining the volume of an object?
Length X width X height= volume Or Cross sectional area X length= volume (Cross sectional area= area of a face if the object)
Cross sectional area of concrete slab?
The cross-sectional area of a concrete slab is the total area of the slab when viewed perpendicular to its length and width. To calculate the cross-sectional area, you multiply the length of the slab by the width of the slab. This measurement is crucial for determining the amount of concrete needed for a project and for ensuring the structural integrity of the slab.
What is the relationship between resistance and cross-sectional area in a conductor?
The relationship between resistance and cross-sectional area in a conductor is inversely proportional. This means that as the cross-sectional area of a conductor increases, the resistance decreases, and vice versa. This relationship is described by the formula: Resistance (resistivity x length) / cross-sectional area.
The magnitude of the resistance of a wire depends on?
Temperature, Length of wire, Area of the cross-section of wire and nature of the material.
State the factors affecting resistance of materials?
The resistance of materials is primarily affected by temperature, material composition, length, and cross-sectional area. As temperature increases, resistance typically increases for most conductors. Additionally, materials with higher resistivity, such as insulators, exhibit greater resistance. The length of the conductor directly impacts resistance, with longer materials having higher resistance, while a larger cross-sectional area reduces resistance.
What are the four factors affecting resistance and how do they affect it?
The four factors affecting resistance are material, length, cross-sectional area, and temperature. Resistance increases with longer length and higher temperature, while it decreases with larger cross-sectional area. The material used also plays a role, with materials like copper having lower resistance compared to materials like steel.
What are the factors affecting the resista nce of a wire?
The factors affecting the resistance of a wire are its length, cross-sectional area, resistivity of the material, and temperature. As the length of the wire increases, the resistance also increases. A larger cross-sectional area decreases resistance, while higher resistivity materials and increased temperature contribute to higher resistance.
What affects the electrical resistance of a body?
The electrical resistance of a body is affected by the material it is made of, its length, cross-sectional area, and temperature. Materials with high resistivity, longer lengths, smaller cross-sectional areas, and higher temperatures will have higher electrical resistance.
