Oceanography covers a wide range of topics, including marine life and ecosystems, ocean circulation, plate tectonics and the geology of the seafloor, and the chemical and physical properties of the ocean. Just as there are many specialties within the medical field, there are many disciplines within oceanography.
Answer:
Efficiency is the percent of work put into a machine by the user (input work) that becomes work done by the machine (output work). The output work is always less than the input work because some of the input work is used to overcome friction. Therefore, efficiency is always less than 100 percent.
<span>A. The buoyant force only acts on objects in water. - The buoyant force can act in ANY liquid, not just water
B. The buoyant force is always stronger than the force of gravity. - This is false. The buoyant force is dependent on the size of the object and not gravity
C. The buoyant force causes objects to sink more quickly than 9.8 m/s2. - This is false, since the buoyant force ALWAYS acts opposite of gravity.
D. The buoyant force always pushes objects up towards the surface of the fluid.
- This is true</span>
Missing text in the problem (found on internet):
"<span>A 70 cm -long steel string with a linear density of 1.0 g/m is under 200 N tension. It is plucked and vibrates at its fundamental frequency"
Solution:
The frequency of the sound wave along the string is given by
</span>

<span>where L=70 cm=0.7 m is the length of the string, T=200 N its tension and </span>

is the linear density. Using these values in the formula, we find
