Answer:
x=0.01457 m
Explanation:
From parallel axis theorem
I=Icm+mh²
where h=x
The rotational inertia about its center of mass is
Icm=mL²/12
where L=1.0 m
Thus T=4.8s we obtain
After Solving this quadratic we get
x₁=5.702 m
x₂=0.01457 m
One of the solution is an impossible value for x (x=5.70m is greater than L)
So we choose the other one
x=0.01457 m
Transverse Waves: Displacement of the medium is perpendicular to the direction of propagation of the wave. ... Longitudinal Waves: Displacement of the medium is parallel to the direction of propagation of the wave.
Hello
I think some details of the question are missing. However, I believe you are referring to a bob following some circular path. Therefore, the answer is "no": in fact, the centripetal force is equal on the earth and on the moon.
Keep in mind that the centripetal force is given by
where m is the mass, v the tangential velocity and r the radius of the circular motion. The mass m of the bob is the same on the earth and on the moon, so the centripetal force is the same.
Blasts are used for communicating different signals when vessels move.When a boat is leaving, a long blast, at intervals of not more than two minutes, is used for alerting other vessels, when a boat is sailing. When leaving the dock, only a single prolonged blast is used for indicating others, that you are leaving.
