Provides the needed light as it can be dark underwater.
1. Provides the needed light as it can be dark underwater.
Answer:
Get a light that has a 120 degree beam to cover the entire frame. 2000 lumens will be a great number to start from in total, so either one light of 2000+ or two lights of 1000+. As we mentioned above, the higher the output the better reach you will have.

6. A scuba diver needs a diving tank in order to provide breathing gas while he is underwater .how much pressure is needed for 6.00 liter of gas at 1.01 Atmospheric pressure to be compressed in a 3.00 litter cylinder
Answer:
The pressure needed to compress the gas in a 3-liter cylinder is 2.02 atm.
Explanation:
This problem is an application of Boyle's Law. Boyle's law is a gas law that relates pressure of a gas to its volume. This law states that the pressure of a gas is inversely proportional to the volume at constant temperature.
The equation for this law is as follows:
P₁V₁ = P₂V₂
where;
P₁ is the initial pressure of the gas
V₁ is the initial volume of the gas
P₂ is the final pressure of the gas
V₂ is the final volume of the gas
This equation is the one we are going to use to solve the problem.
Given:
P₁ = 1.01 atm
V₁ = 6 L
V₂ = 3 L
Required:
P₂
Solution:
P₁V₁ = P₂V₂
P₂ = P₁V₁ ÷ V₂ or P₂ =
P₂ =
P₂ = 2.02 atm
Therefore, the final pressure needed to compress the gas to a 3 L cylinder is 2.02 atm.

8. how can fish breath underwater? explained scientifically
Answer:
Fish must get their oxygen from the water. This process requires large volumes of water to pass through absorption surfaces to get enough oxygen into their bodies using their mouths and gills.Answer:It uses their gills
What is GillsFish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments.
Why does fish needs their gillsLike us, fish also need to take in oxygen and expel carbon dioxide in order to survive. But instead of lungs, they use gills. As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that's dissolved in the water.

10. How can you improve underwater swimming
Here are 5 tips to maximize time underwater.
1. Maintain a tight streamline
Swimmers reach maximum speed right at the end of the push-off, before drag starts to take hold. In this moment, reducing drag is a critical factor in improving the underwater portion of a swim.
The easiest, most effective way to reduce drag is to keep a tight streamline position throughout the underwater phase. This will allow you to go farther, faster.
2. Aim for high push-off strength
Given that the fastest speed for any given length occurs right at the end of the push-off, a stronger push-off will produce greater speed that can be sustained longer during the underwater phase.
A powerful push-off helps you accelerate off the walls quicker, and provides more speed to carry you through the underwater all the way to the breakout and stroking portion of the swim.
3. Know when to break surface
A large part of maximizing time underwater is breaking out at the optimal time. Taking the first stroke too early minimizes the advantage gained from the initial speed off the walls. Conversely, spending too long underwater will also slow you down.
The ideal distance to break surface is at the point where speed underwater drops far enough to match maximum stroking speed.
4. Be consistent
Most swimmers tend to drop time underwater as a race progresses, but one thing that sets faster swimmers apart is their ability to maintain consistency throughout the race.
The key is to focus on producing consistent time underwater, without sacrificing distance or speed. This means being consistent with a strong push-off and powerful dolphin kicks.
5. Have a strong up-kick
In dolphin kicks, most swimmers tend to have a strong down kick and weaker up kick. While majority of the propulsive force comes from the down kick, the up kick is also a significant source of speed.
To truly maximize time underwater, every component should be optimized. A missed detail is a missed opportunity to swim faster.

14. a scuba diver needs a diving tank in order to provide breathing gas while he is underwater how much pressure is needed for 10,00 liters of gas at 4.00 atmospheric pressure to be compressed in a 5100 mL cylinder
SOLUTION:
Step 1: List the given values.
[tex]\begin{aligned} & P_1 = \text{4.00 atm} \\ & V_1 = \text{10.00 L} \\ & V_2 = \text{5100 mL = 5.100 L} \end{aligned}[/tex]
Step 2: Calculate the final pressure by using Boyle's law.
[tex]\begin{aligned} P_1V_1 & = P_2V_2 \\ P_2V_2 & = P_1V_1 \\ \frac{P_2V_2}{V_2} & = \frac{P_1V_1}{V_2} \\ P_2 & = \frac{P_1V_1}{V_2} \\ & = \frac{(\text{4.00 atm})(\text{10.00 L})}{\text{5.100 L}} \\ & = \boxed{\text{7.84 atm}} \end{aligned}[/tex]
Hence, the pressure needed is 7.84 atm.

17. how does nature provide for the safety and survival of underwater creatures? give examples. NEED NOW pls
Answer:
There are several ways deep-ocean animals survive in such an environment.
First off, the deep ocean is dark because sunlight can’t penetrate very far into the water. Many animals make their own light, called bioluminescence, to communicate, find mates, scare predators, or attract prey. Bioluminescence looks a bit like the glow sticks you use on Halloween, but is made naturally by chemical reactions within an animal.
Most of the deep ocean is cold, usually lower than the temperature in your refrigerator. Deep-sea animals don't mind the cold at all, and many can only survive and grow in the cold.
Food is scarce in much of the deep sea, in part because photosynthesis only takes place at the ocean’s surface where there’s sunlight. Most animals cope with this by being very small and needing less to eat or by growing very slowly. Big animals that travel long distances to find food eat huge amounts and store food for many months between meals.
Light, pressure, temperature, and food are typical features of the ocean that remain stable over long periods, allowing animals time to evolve in order to survive. However, humans are changing the deep ocean at a rapid rate through oil and gas drilling, fishing, waste disposal, and mining. Animals may not have time to adapt to the changes brought about by these activities. For this reason, we must think about ways to protect deep ocean-dwelling creatures.

18. why can fish live underwater ?
Answer:
Fish live underwater. Fish do not breathe air. They get the oxygen they need from the water they live in. Fish have special filters in the sides of their body called 'gills' that act as their 'lungs'.
The main reason for fish ability to breathe underwater is the fact that fish are cold-blooded, which means they need small oxygen amounts to complete the breathing process.

With the benefit of breathing pure oxygen first, the current Guinness World Record for holding your breath underwater is held by Aleix Segura of Spain at a whopping 24 minutes 3 seconds!
Most people in good health can hold their breath for approximately two minutes. Experts believe that even a little bit of practice can increase that amount of time quite a bit. However, they also warn that depriving your body of oxygen can have many negative effects, so don't make a habit of holding your breath for very long!

22. a scuba driver needs a diving tank in order to provide breathing gas while he is underwater. How much pressure is needed for 6.00 liters of gas at 1.01 atm to be compressed in a 3.00 liter cylinder
Boyle's Law states that at constant temperature, pressure is inversely proportional to volume.
Given:
P₁ = 1.01 atm
V₁ = 3.00 liters
P₂ = ?
V₂ = 6.00 liters
Equation:
P₁V₁ = P₂V₂
Derive the equation for P₂:
[tex] \frac{P _{2}V _{2} }{V _{2} } = \frac{P _{1}V_{1} }{V _{2} } [/tex]
P₂ = (P₁V₁) ÷ V₂
P₂ = [(1.01 atm) (3.00 liters)] ÷ 6.00 liters
P₂ = (3.03 atm·liters) ÷ 6.00 liters
P₂ = 0.505 atm (follow the rule in significant digits)
ANSWER: A pressure of 0.505 atm is needed for 6.00 liters of gas.
ANALYSIS: The law states that pressure is inversely proportional to volume. When the volume increases, the pressure decreases. When the volume decreases, the pressure increases. At constant temperature, when the volume increases from 3.00 liters to 6.00 liters, the pressure decreases from 1.01 atm to 0.505 atm. This is your conclusion to the given problem.
Motivation: Since you are already armed with Boyle's Law, you are now confident to recite in your class. Have a blessed and productive day!
