Question

a body makes SHM on a line of length 20 cm with a frequency 1/4s displacement along y axis after 1/2 s???​

Answer 1

Answer:

please mark me brainliest

Explanation:

Given length=20 cm

so amplitude a =20/2=10cm

Displacement along y axis in shm is given as y=asinwt==10sin2πft since w=2πf

Now y=10×sin2π(1/4)(1/2) =

10×sin(π/4)=10/√2 =5√2
