42:41 Nunber of oscillation = 20
Frequency = Totam Oscillation/Time taken
= 20/1Hz
={20Hz} Ans 😊😊😊
48:44 Paisa hi paisa hoga 😂😂
Pw is better than school 😂😂😂😊

1 oscillation
Frequency=(total oscillation) upon (time taken) = 20/1 Hz
=20 HZ Ans pw best 😊😊

No. of oscillation=20
Frequency= oscillation/time period
20/1
=20hz

1 second= 20 oscillation
Frequency= Oscillation / Time taken
= 20/1 = 20 hz
Because the number of oscillation made by an object in 1 sec is called frequency

Oscillations =20
Total Time = 1 second

Frequency = No. of oscillations

Total Time


F = 20/1
F= 20

Ans:= 《20Hz》

42:22 frequency=Total oscillation/time taken

20/1=20(HERTZ)

Q1=Frequency :Number of oscillators/time
:20/1 =20per sec or 20Hz
Thank you sir

1 oscillation - 1hz
Frequency = (total oscillation ) upon( total time taken )
=20 oscillation
=1. Hz
Ans = 20 hz

1 oscillation -1hz
Frequency - total oscillation/total time taken
=20/1
=20hz😊
