When you dive for a coin at the bottom of a pool, the light refraction at the water-air interface causes the image of the coin to appear higher than its actual position. This bending of light makes the coin look like it's somewhere it's not, leading you to misjudge its location.
The rock was tied to a string to prevent it from sinking to the bottom of the water body. The string allowed the rock to be lowered into the water and then retrieved easily without having to dive in.
The diver's gravitational potential energy just before the dive is at its maximum, as the diver is at the highest point in the dive and has the most gravitational potential energy. This potential energy will be converted to kinetic energy as the diver falls during the dive.
A gannet primarily uses gravity to dive into the water, accelerating downwards due to its weight. It also uses its wings to control the speed and direction of its dive, enabling it to plunge into the water with precision to catch fish.
The diver's gravitational potential energy just before the dive will depend on the diver's mass, the height from which they are diving, and the acceleration due to gravity. The potential energy can be calculated using the equation PE = mgh, where m is the mass of the diver, g is the acceleration due to gravity, and h is the height of the dive.
Executing a swan dive involves converting potential energy (stored energy due to the diver's height above the water) into kinetic energy (energy of motion as the diver accelerates downward).
it is an optical illusion (the coin appears to straight ahead but yet it is somewhere else)
because it makes the force make bigger and does notmove
It's not where it appears to be because the sun's rays are reflecting off of the water surface, and the water surface are bending the rays, so it looks like the coin is somewhere else.
As light changes from one medium to another, it changes speed and bends. This is called refraction. The light rays actually slow down when going down when going from the air to the water. This means that the coin looks like it is in a different location than it actually is.
Dive to the Bottom of the World - 2009 TV was released on: USA: 7 October 2009
The deepest dive to the bottom of Atlantic ocean was 10,994 meters deep. It was done by Don Walsh in a submarine and the dive took 4 hours and 47 minutes.
Straight to the bottom of the ocean.
Orcas can dive upto a 1,000 feet (304.8m).
All the way to the bottom.
Dive to the bottom and then go left.
The maximum bottom time for a dive to 100 feet depends on several factors, including the diver's experience level, the type of dive (recreational or technical), and the use of enrichment gases. For recreational divers using air, the no-decompression limit is typically around 20-30 minutes, but this can vary based on individual dive tables or computers. It's essential to consult a dive table or computer tailored to the specific dive conditions to determine the safe bottom time and ensure proper ascent and safety stops. Always prioritize safety and consider the risks associated with deeper dives.
