Answer:

Gravitation for exert on block along slope = Mgsin30

Since net force is 0 (constant speed)

Frictional force = Mgsin30

C(friction) = Frictional Force/Normal Force

Normal Force = Mgcos30

C(friction) = Frictional Force/Normal Force

=Mgsin30/Mgcos30

= tan 30

=0.577

Tems11 [23]
<span>10 hertz Hertz is the frequency of oscillation which is the number of oscillations per second. So if something takes 0.10 s per oscillation, divide 1 second by the period to get the frequency. So 1 / 0.10s = 10 1/s = 10 Hertz Therefore the object is vibrating at 10 hertz.</span>
