An ocean's salinity is affected by water and air temperature, the volume of water that flows into it, its age and the chemical composition of surrounding geological formations.<span> Because the effect of these factors varies over the area of an ocean, different levels are found within the ocean</span>
Ocean waves and sound waves are : mechanical wave. A and B aren't right at all. and C is wrong because they aren't electromagnetic.
Mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.
Hope this help

Answer:
thankkkk youuuu soo muchhh
Answer:
Explanation:
Length of bar = L
mass of bar = M
mass of each ball = m
Moment of inertia of the bar about its centre perpendicular to its plane is
Moment of inertia of the two small balls about the centre of the bar perpendicular to its plane is
Total moment of inertia of the system about the centre of the bar perpendicular to its plane is
I = I1 + I2
