A hanging wire made of an alloy of aluminum with diameter 0.12 cm is initially 2.4 m long. When a 37 kg mass is hung from it, the wire stretches an amount 1.24 cm. A mole of aluminum has a mass of 27 grams, and its density is 2.7 g/cm3. Based on these experimental measurements, what is Young's modulus for this alloy of aluminum?

The Young's modulus for this alloy of aluminum is

Explanation:

Given that,

Diameter = 0.12 cm

Length = 2.4 m

Mass = 37 kg

Stretch length = 1.24 cm

Density = 2.7 g/cm³

We need to calculate the area

Using formula of area

Put the value into the formula

We need to calculate the Young's modulus

Using formula of Young's modulus

Put the value into the formula

Hence, The Young's modulus for this alloy of aluminum is

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

the right answer is 0.3 meters per second
