What is the formula for calculating resistance if the resistivity is 4.3 10-3 A?
The formula for calculating resistance (R) using resistivity (ρ) is given by ( R = \frac{\rho \cdot L}{A} ), where ( L ) is the length of the conductor and ( A ) is the cross-sectional area. In the given context, if the resistivity is ( 4.3 \times 10^{-3} , \Omega \cdot m ), you would need the length and cross-sectional area of the conductor to calculate the resistance. Without those values, the resistance cannot be determined solely from the resistivity.
What is the formula of calculating weight of a round bar of en1a material if its diameter and length is given?
Density or weight is calculated by mass/volume
How is the width of a box calculated?
To calculate the width of a box, or cube, you need to use the following formula: W = (V) / (LxH) given that (V= volume, L= length, W= width, H= height) and volume, height and length measurements are already given.
How do you find weight if length breadth and height is given?
You aslo need to know the density of the matter being calculated. multiply the density by the volume to get the weight
is it construct two wires of the same length one of copper and one of iron that would have the same resistance at the same temperature?
Yes, it is possible to construct two wires of the same length, one of copper and one of iron, that have the same resistance at the same temperature. The resistance of a wire is determined by its resistivity, length, and cross-sectional area, as given by the formula ( R = \frac{\rho L}{A} ). Since copper has a lower resistivity than iron, the copper wire would need a larger cross-sectional area than the iron wire to achieve the same resistance.
What is the ration to resistance force to effort force?
The mechanical advantage is given by the ratio of resistance force to effort force. It represents the factor by which a simple machine multiplies the force applied to it. Mathematically, it can be calculated as mechanical advantage = resistance force / effort force.
How does the resistance of a wire depend on its dimensions?
The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. This means that for a given material, a longer wire will have higher resistance and a thicker wire will have lower resistance. The relationship is described by the formula: Resistance = resistivity x (length / cross-sectional area).
An electric heater is stretched to increase its length by 25 percent what is the increase in resistance?
The resistance of the electric heater will increase by approximately 56.25% (25% increase in length results in a 56.25% increase in resistance). This relationship is given by the formula: new resistance = (1 + 0.25)^2.
What is formula of cylinder if the base are given?
Neither the area or the volume of the cylinder can be calculated without the length.
What does resistance in wire depend on?
Resistance is directly proportional to the resistivity and length of the conductor, and inversely-proportional to its cross-sectional area. As resistivity is affected by temperature, we can say that temperature indirectly affects resistance.
Urgent I need to know how to find it by 9pm est so i can take the test How do you find the volume of a rectangular box if you were given the areas of the sides r s and t?
The volume is calculated by length*width*height. If you are only the area then you could not solve the problem without be given the length of one of the sides. The area is calculated as length*width.
How can I find the pressure from a given flow rate?
To find the pressure from a given flow rate, you can use the formula: Pressure Flow Rate x Resistance. The resistance is typically provided in the system specifications or can be calculated based on the system's characteristics. By multiplying the flow rate by the resistance, you can determine the pressure in the system.
What is the resistance of a wire with p of .25 a length L of 11.2 and an area A of 1.26?
More data is needed. What is the material of the wire - copper -steel - etc. The physical units associated with the numbers are needed. Are they inches - ohms - etc. These units are needed. Please reformulate your query.
How many unique substrings of length k can be found within the given text?
The number of unique substrings of length k in the text can be calculated using the formula: (n-k1), where n is the length of the text.

What is the formula to find resistance force?
The formula to find resistance force is given by R = F/A, where R is the resistance force, F is the force applied, and A is the area over which the force is applied. This formula is often used in physics and engineering to determine the resistance force in various scenarios.
