Question

The extension of an elastic spring is found to vary directly with the weight
suspended from it. If a weight of 75 kg produces an extension of 1.4 cm,
calculate the weight that would produce an extension of 9.8 cm.​

Answer 1

Answer

the extension of an elastic spring found to vary directly with the weight

the extension of an elastic spring found to vary directly with the weightsuspended from it

the extension of an elastic spring found to vary directly with the weightsuspended from itso write

the extension of an elastic spring found to vary directly with the weightsuspended from itso writelaw

the extension of an elastic spring found to vary directly with the weightsuspended from itso writelaw=> 1 = kw (1)

the extension of an elastic spring found to vary directly with the weightsuspended from itso writelaw=> 1 = kw (1)where k = proportionality constant

the extension of an elastic spring found to vary directly with the weightsuspended from itso writelaw=> 1 = kw (1)where k = proportionality constant|= represent the extension of an elastic spring
