How do you calculate a cross-sectional area When all you know is resistance resistivity and length?
I think the equation you are looking for is Resistance (ohms) = Resistivity * Length / Area or R=p*L/A. This is the resistance of a circular wire with cross-section of A, length of L, and material with resistivity p. So to get area: Area = Resistivity * Length / Resistance.
How do you calculate resistivity of copper wire?
(rho) or resistivity of a "wire" is calculated using this formule:rho = Resistance x Area / length of materialthe resistivity of copper is 1.7 x 10 -8 ohm/mResistivity is measured in ohm metres, NOT ohms per metre!

Would a full concert hall have different reverberation from an empty hall?
the concert hall has fabric on the walls that absorbs the sound and a gym doesnt
How long did the Danish Halls Stand empty?
the Danish hall or "Herot" stood empty for 12 years or (12 winters)
How long does Herot remain empty?
There is a weeping man.
Why there are fewer echo in the school hall when it is full of children then when it is empty?
The children's bodies absorb much of the sound. When the hall is empty, the sound can bounce back off the walls and ceiling. Lining the hall with polystyrene tiles would have the same effect as when the children were present.
What quantities are needed to calculate an object's resistance?
To calculate an object's resistance, you would need to know the material's resistivity, its length, cross-sectional area, and temperature (if it's a variable). Using these values, you can apply the formula R = ρ * (L/A) to calculate the resistance, where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
Would have the same resistance as a copper wire that is 4 m long and has a cross-sectional area of 0.066 cm2?
A wire with the same resistance as the given copper wire would have the same resistivity as copper. The resistance of a wire is dependent on its resistivity, length, and cross-sectional area. To calculate the resistance of a wire, use the formula R = (resistivity * length) / area; however, without the specific resistivity value, an exact value cannot be provided.
When a sample of germanium and silicon having same impurity density are kept at room temperature then resistivity of both?
The resistivity of germanium will decrease with increasing temperature due to a positive temperature coefficient of resistivity, while the resistivity of silicon will increase with increasing temperature due to a negative temperature coefficient of resistivity. At room temperature, silicon will have a higher resistivity compared to germanium.
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 name is given to the reflected sound waves in a cave or an empty hall?
Ah, what a lovely question! Those reflected sound waves in a cave or empty hall are called echoes. Just imagine the sound bouncing off the walls like a little dance, creating a beautiful harmony of nature. Embrace those echoes, my friend, they add a touch of magic to the world around us.
