Answer:
8.80 Hz
Explanation:
The frequency of a loaded spring is given by

where k and m are the spring constant and the mass of the load respectively. The values of these do not change because they are internal properties of the components of the system.
Hence, the frequency of the vertical spring mass does not change and is 8.80 Hz.
On the other hand, the frequency of the simple pendulum is affected because it is given by

where g and l are acceleration due to gravity and length of the pendulum, respectively. It is thus seen that it depends on g, which changes with location. In fact, the new frequency is given by

Velocity is the same as the formula for speed, the only difference is
velocity has direction. Velocity is distance over time. Given is 4,400
kilometers travelled west in 4 hours. Applying the given equation, we wil have
4,400/4 = 1,100 km/hr west
Answer:
same problem is here also bro i cannot find this plz help anyone
If it takes 1 year for this crab to travel 5,70km
Then, it will takes approximatly 1000/5,70 = 175 years to travel 1000 km
