hope it help u

Answer 2

$\huge\underline{\bf \red{ ❥ ᴀɴsᴡᴇʀ }}$

Time Period,

Time period = Time/No. of oscillations in time

→ Time period = 4/40

→ Time period = 0.1 sec

Frequency,

Frequency = 1/Time period

→ Frequency = 1/0.1

→ Frequency = 10 Hz

Hence, the time period is 0.1 sec & frequency is 10 Hz.
