What will happen to the resistance of a wire if it is stretched to increase its length by 4 times?
Assume that the increase in length is achieved by uniform reduction in the cross-sectional area of the wire. Then an increase in length by 4 times will result in the cross sectional area being reduced to a fifth of it original value. This will increase the resistance to five times its previous value.
What happens to the acceleration if the force applied is increase three times?
it is tripled
How many times does the volume of a sphere increase if the radius is tripled?
The new volume is 3^3 = 27 times as much.
What is the effect on the volume of a cube if its side length is tripled?
The volume increases to 33 = 27 times as much.
What will happen to the resistance of a wire if it is stretched to increase its length by 2 times?
Actually resistance is directly proportional to the length provided area remains constant. But as we stretch the wire only its volume would remain constant. So its area is to be decreased as length increases. V = pi r^2 * L Now we have R = K * L / pi r^2 Multiplying numerator and denominator by L we get R = K/V * L^2 So resistance is found to be proportional to square of length Hence as length gets increased by 2 times, its resistance value would increase by 4 times.
What happens to the area of a rectangle when the length and width are 3 times as big as they were before?
When the length and width are tripled, the area becomes (3 x 3) = 9 times as much as before.
What are mathematical relationship between resistance and specificconductivity constant?
Cell constant(C) = Resistance(R) X Specific Conductivity(K)
How many times is the period of the pendulum increased or decreased when its length is increased four times?
Time period is directly proportional to the square root of the length So as we increase the length four times then period would increase by ./4 times ie 2 times.
Is there a direct correlation between increase in coil wraps and electrical resistance of a guitar pickup?
There is a direct relationship between the length of wire (thus the number of times the wire is wrapped) and the electrical resistance of the guitar pickup, measured at the two output terminals.
If the length of a rectangular prism is doubled its width is tripled and its height remains the same what is the volume of the new rectangular prism?
just did this on castle learning the answer is six times
What happens to the resistance as the area increases?
Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.
Which is a better conductor between a short wire and long wire?
Double the length is double the resistance. Resistance of a wire is the resistivity of the material, times the length, divided by the cross-section area.
