Answer:

Below :)

Explanation:

A) 720/3 =240. 40 per minute.

B) 720/180 = 4 per second.

C) T=1/4 s^-1 (the formula) = 1/4 s. (The time peroid.)

D) V=1/T

V= 4 Hz

An oscillator makes 720 vibrations in 3 minutes. so, we have to solve the given problems based on it ~

#1. what's the number of vibrations per minute •

[tex]\qquad \sf \dashrightarrow \: 3 \: min = 720 \: vib[/tex]

[tex]\qquad \sf \dashrightarrow \: 1 \: min = \dfrac{720}{3} [/tex]

[tex]\qquad \sf \dashrightarrow \: 1 \: min = 240 \: vib[/tex]

#2. Calculate unit vibrations per second •

[tex]\qquad \sf \dashrightarrow \: 1 \: min = 240 \: vib[/tex]

[tex]\qquad \sf \dashrightarrow \: 60 \: sec = 240 \: vib[/tex]

[tex]\qquad \sf \dashrightarrow \: 1 \: sec = 4 \: vib[/tex]

#3. What's it's time period •

time taken to do 1 vibration is known as a period, so we can infer that :

[tex]\qquad \sf \dashrightarrow \: 1 \: vib = \dfrac{1}{4} \: sec[/tex]

[tex]\qquad \sf \dashrightarrow \: t = 0.25 \: sec[/tex]

#4. what is it's frequency in hert •

[tex]\qquad \sf \dashrightarrow \: f = \dfrac{1}{t} [/tex]

[tex]\qquad \sf \dashrightarrow \: f = \dfrac{1}{0.25} [/tex]

[tex]\qquad \sf \dashrightarrow \: f = 4 \: hertz[/tex]
