Answer:
To see objects at the surface of water from a submarine underwater, the instrument used is a periscope. Here is a detailed explanation:
What is a periscope?
A periscope is an optical instrument that uses a system of mirrors or prisms to allow an observer to see objects that are not in their direct line of sight. It is commonly used in submarines to view objects above the water's surface while the submarine remains submerged.
How does a periscope work?
A periscope typically consists of a long tube with two mirrors or prisms at opposite ends. The mirrors/prisms are positioned at a 45-degree angle to the tube, which allows light to be reflected twice and change the direction of the image. The top mirror/prism reflects the image from above the water surface down the periscope tube, and the bottom mirror/prism reflects the image to the observer's eye, providing a clear view of the surface.
Advantages of using a periscope:
- Submarines can remain submerged while still having the ability to observe objects at the water's surface.
- It provides a wide field of view, allowing the observer to scan the surrounding area.
- The use of mirrors/prisms ensures that the image is not distorted or blurred.
Other instruments and their uses:
- Kaleidoscope: A kaleidoscope is a toy or optical instrument that creates colorful and symmetrical patterns by reflecting light off mirrors. It is not used for observing objects at the water's surface from a submarine.
- Spectroscope: A spectroscope is an instrument used to analyze the properties of light. It is not used for observing objects at the water's surface from a submarine.
- Telescope: A telescope is an optical instrument used to view distant objects by collecting and focusing light. While it can be used to observe objects above the water's surface, it is not specifically designed for use in submarines and may not be suitable for underwater viewing.
Therefore, the correct instrument used for seeing objects at the surface of water from a submarine underwater is a periscope.

Fathometer is used to measure ocean depth.
Explanation:
A fathometer is a device used to measure the depth of water in oceans, seas, and other bodies of water. It works on the principle of sound waves and their reflection from the ocean floor. Here is a detailed explanation of how a fathometer works:
- Principle: The fathometer uses sound waves to determine the depth of water. It sends an acoustic pulse (sound wave) towards the ocean floor and measures the time it takes for the pulse to return to the device.
- Sound waves: Sound waves travel through water at a known speed. By measuring the time it takes for the pulse to return, the fathometer calculates the depth of water based on the speed of sound.
- Transducer: The fathometer consists of a transducer, which is a device that emits and receives sound waves. The transducer is usually mounted on the bottom of a boat or ship and is submerged in the water.
- Reflection: When the sound wave reaches the ocean floor, it reflects back towards the transducer. The transducer detects the reflected wave and measures the time it took to travel.
- Depth calculation: Using the known speed of sound in water, the fathometer calculates the depth by multiplying the time taken by the speed of sound and dividing it by 2. This is because the sound wave has traveled to the ocean floor and back, so the actual depth is half of the total distance traveled.
- Display: The fathometer displays the calculated depth on a screen or dial, allowing the user to know the depth of the water at a specific location.
Overall, a fathometer is an essential tool for maritime navigation, underwater mapping, and scientific research to determine the depth of oceans and other bodies of water accurately.

Explanation:
The free surface of a liquid refers to the surface that is not in contact with any solid object. It behaves like a sheet and tends to contract to the smallest possible area due to the force of cohesion. Cohesion is the force of attraction between molecules of the same substance.
Here is a detailed explanation of why the force of cohesion causes the free surface of a liquid to contract:
1. Force of cohesion:
- The force of cohesion is responsible for the attractive forces between molecules of the same substance.
- In the case of a liquid, the cohesive forces between the liquid molecules pull them closer together.
- These cohesive forces are stronger at the surface of the liquid, as the molecules at the surface do not have molecules on all sides to interact with.
2. Surface tension:
- The force of cohesion leads to the phenomenon of surface tension.
- Surface tension is the tendency of the surface of a liquid to behave like a stretched elastic sheet.
- It is caused by the cohesive forces between the liquid molecules, which pull the molecules at the surface inward, causing the surface to contract.
3. Smallest possible area:
- The surface of a liquid tends to contract to the smallest possible area to minimize the energy associated with the surface tension.
- This contraction of the surface reduces the surface area and brings the liquid molecules closer together, thereby minimizing the surface energy.
4. Capillary action:
- The force of cohesion and surface tension also play a role in capillary action, where liquids rise or fall in narrow tubes or capillaries.
- Capillary action is a result of the balance between the adhesive forces between the liquid and the tube's walls and the cohesive forces within the liquid itself.
- The cohesive forces cause the liquid to rise in the tube, as the surface tension pulls the liquid molecules upward.
In conclusion, the free surface of a liquid tends to contract to the smallest possible area due to the force of cohesion. This is because the cohesive forces between the liquid molecules cause surface tension, which leads to the contraction of the liquid's surface.

Exposure to sunlight helps a person improve his health because:
1. The ultraviolet rays convert skin oil into Vitamin D:
- Sunlight is a natural source of ultraviolet B (UVB) rays, which are necessary for the synthesis of vitamin D in our skin.
- When UVB rays penetrate the skin, they convert a cholesterol compound in the skin oils into vitamin D3.
- Vitamin D plays a crucial role in maintaining healthy bones, regulating calcium levels, and supporting the immune system.
2. Increased resistance power:
- Exposure to sunlight has been linked to an increase in the production of white blood cells, which are responsible for fighting off infections and boosting immune function.
- Sunlight also stimulates the production of nitric oxide, a compound that helps dilate blood vessels and improve blood flow, thereby enhancing overall cardiovascular health.
3. Improved mood and mental health:
- Sunlight exposure triggers the release of serotonin, a neurotransmitter that regulates mood and promotes feelings of happiness and well-being.
- Sunlight has also been found to reduce symptoms of seasonal affective disorder (SAD) and improve overall mental health.
4. Stimulation of pigment cells in the skin:
- When the skin is exposed to sunlight, the pigment cells called melanocytes produce a pigment called melanin, which gives the skin a tan.
- Melanin acts as a natural defense mechanism against UV radiation, providing some protection against sunburn and skin damage.
5. Regulation of circadian rhythm:
- Exposure to natural sunlight helps regulate the body's internal clock, known as the circadian rhythm.
- Sunlight exposure in the morning helps signal the body to wake up and promotes a regular sleep-wake cycle, leading to better sleep quality and overall well-being.
In conclusion, exposure to sunlight provides numerous health benefits, including the synthesis of vitamin D, improved immune function, enhanced mood and mental health, regulation of the body's internal clock, and stimulation of pigment cells in the skin.
