Answer 1

Answer:

frequency. main answer

Explanation:

verified answer

Answer 2

Explanation:

this is the wave equation of the form y=a sin(wt+phi)

here a= amplitude

sin=sinusoidal function

wt=the angular frequency

phi=phase angle

so from this equation y=100sin(200pi t+0.05)

amplitude=100

angular frequentcy=200 pi rad/s

frequency= w=2pi.f so f=w/2.pi= 200 pi/2 pi, so f=100 Hz

time period= 1/f =1/100=0.01 secs

phase angle=0.05
