Answer:
7.5 rad/s
Explanation:
= angular acceleration = (0.2) θ
Angular acceleration is given as




Integrating both side


w = 7.5 rad/s
When gas hydrates are brought to the surface, they evaporate quickly. This would be the biggest, current disadvantage to using gas hydrates as a form of energy.
Given :
A rope 6m long is fixed at one end, the other end is attached to a light string so that it is free to move.
The speed of waves on the rope is 18 m/s.
To Find :
The frequency of the second harmonic.
Solution :
We know, for second harmonic wave :
Wavelength = Length of rope

Now, we know frequency is given by :

Therefore, the frequency of the second harmonic is 3 s⁻¹.
Answer:
1/4 as much

I don't know the explanation
Answer:
The distance to the moon greater than the distance across the Atlantic ocean by an order of 1.
Explanation:
We have the average distance across the Atlantic ocean, 
the average distance to the moon, 
The factor by which the distance to moon is greater than the width of Atlantic ocean:



i.e.
the distance to the moon greater than the distance across the Atlantic ocean by an order of 1.
