Water presents a much higher resistance than air.

How does a decrease in velocity affect the frequency and wavelength of the waves entering the shallow water?
The frequency stays the same and wavelength decreases
If the diver doesn't have the correct form when she enters the water the force of the water can accelerate her speed?
ask me agin later im in a bad mood and cramping
Who will hear the sound of an approaching boat first this diver or his friend above the water?
The diver
A diver springs upward with an initial speed of 1.8meters per second from a 3.0 meter board what is the velocity when the diver reaches the water What is the highest point he reaches above the water?
Vf^2 = Vi^2 +2ad = 1.8m ^2 + 2(-9.8m/s^2)(3.0m) =62.04m/s Vf= sqrt(62.04m/s) =-7.9m/s
Why speed of velocity of sound is greater in hot water than the cold water?
The speed of sound is proportional to the density of the substance it's traveling through. Typically 'colder' water is more dense than 'hotter' water, and therefore sound would travel at a greater speed through colder water. However, there is a point right above the freezing temperature for water in which a decrease in temperature would cause a decrease in density due to the polar molecule behavior of water. Talking about the velocity of sound is a bit pointless, as it doesn't typically have a 'direction.'
Does lightspeed decrease when entering water?
Yes the lightspeed decrease when entering in water
What is the speed of a diver hitting the water from a height of ten meters?
Terminal velocity
The picture shows a Cartesian diver made from a plastic bottle filled with water and an inverted test tube partially filled with water. What causes the diver to sink as the bottle is squeezed?
The volume of air in the driver decrease.
Why does a diver change his body position before and after diving in the pool?
Hence the diver must spin faster when moment of inertia become smaller to conserve angular momentum. In this way the diver can make more somersaults before entering the water. Related To Chapter CIRCULAR MOTION

What do you call someone who goes into water headfirst?
a diver
If the diver doesn't have the correct form when she enters the water the force of the water can accelerate her speed?

What is a person who goes into water headfirst is called?
Its called a dive
What is the reason for putting tanks in water along with the scuba diver?
so the diver can breath.
Who will hear the sound of an approaching boat first this diver or his friend above the water?
The diver
A Cartesian diver made from a plastic bottle filled with water and an inverted test tube partially filled with water What causes the diver to sink as the bottle is squeezed?
"The volume of air in the diver decreases."
Can the mass of the diver be predicted if the volume of the water it displaces is known?
No. That only tells you the diver's volume.
