A simple pendulum consists of a ball connected to one end of a thin brass wire. The period of the pendulum is 1.45 s. The temperature rises by 142 C°, and the length of the wire increases. Determine the change in the period of the heated pendulum.

    assuming you have zero calculus.

    period=2PI sqrt (l/g)
    solve for original length l.

    now, change in length=l*coeffexpansion*dTemp
    now compute change in length.

    add that to the oiginal length, compute new period, then change in period.

    If you have calculus, it is straigthforward.
