Answer:

Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a common example. In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders THROUGHOUT the machine and becomes pressurised according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through HOSES, tubes, and/or pipes.

Hydraulic systems, like pneumatic systems, are BASED on Pascal's law which states that any pressure applied to a fluid inside a closed system will transmit that pressure equally everywhere and in all directions. A hydraulic system uses an incompressible liquid as its fluid, rather than a compressible gas.

The popularity of hydraulic machinery is DUE to the very large amount of power that can be transferred through small tubes and flexible hoses, and the HIGH power density and wide array of actuators that can make use of this power, and the huge multiplication of forces that can be achieved by applying pressures over relatively large areas. One drawback, compared to machines using gears and shafts, is that any transmission of power results in some losses due to resistance of fluid flow through the piping.

An ocean world, ocean planet, water world, aquaplanet or panthalassic planet is a type of terrestrial planet that contains a substantial amount of water either at its surface or within a subsurface ocean.The term ocean world is ALSO used sometimes for astronomical bodies with an ocean composed of a different fluid,such as lava (the case of Io), ammonia (in a eutectic mixture with water, as is likely the case of Titan's inner ocean) or hydrocarbons like on Titan's surface (which could be the most abundant kind of exosea).

Earth is the only astronomical object known to have bodies of liquid water on its surface, although several exoplanets have been found with the right conditions to support liquid water.For exoplanets, current TECHNOLOGY cannot directly observe liquid surface water, so atmospheric water vapor may be used as a proxy.The characteristics of ocean worlds—or ocean planets—provide CLUES to their history and the formation and evolution of the Solar System as a whole. Of ADDITIONAL INTEREST is their potential to originate and host life.

Explanation:

The Mesolithic (Greek: μέσος, mesos "middle"; λίθος, lithos "stone") is the Old World archaeological period between the Upper Paleolithic and the Neolithic. The term Epipaleolithic is often used synonymously, especially for outside northern Europe, and for the corresponding period in the Levant and Caucasus. The Mesolithic has different time spans in different parts of Eurasia. It refers to the FINAL period of hunter-gatherer cultures in Europe and Western Asia, between the end of the Last GLACIAL MAXIMUM and the Neolithic REVOLUTION. In Europe it spans roughly 15,000 to 5,000 BP; in Southwest Asia (the Epipalaeolithic Near East) roughly 20,000 to 8,000 BP. The term is less used of areas further east, and not at all beyond Eurasia and North AFRICA.

Explanation:

Uniform MOTION:

Definition: This type of motion is DEFINED as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers EQUAL distances in equal intervals of time, irrespective of the duration of the time.

Example of Uniform Motion:

If the speed of a car is 10 m/s, it means that the car covers 10 meters in one second. The speed is constant in every second.

Movement of BLADES of a ceiling fan.

Non Uniform Motion:

Definition: This type of motion is defined as the motion of an object in which the object travels with varied speed and it does not COVER same distance in equal time intervals, irrespective of the time interval duration.

Example of Non Uniform Motion:

If a car covers 10 meters in first two seconds, and 15 meters in next two seconds.

The motion of a train.

Now, people usually get confused between uniform motion and uniform acceleration. In the later phenomena, the object is having a constant acceleration in rectilinear motion, which means the object has different speed in every second, which clearly defines that motion is changing.

• ACCORDING to given QUESTION :

Answer: TIME = t = 2 seconds

Explanation:

Given :

Velocity of SOUND = v = 250 m/s

depth or DISTANCE = d = 125 m

We have,

Time (t) = distance /velocity

=> t = 250/125

=> t = 2 sec.

Thus, the time to hear the splash of sound is 2 sec.

The ANSWER is in the IMAGE

The velocity-time graph here represents the variation of the velocity of race-horse with respect to time.

Since velocity is a vector quantity, direction matters. Positive and negative velocity both carry different meanings.

A race-horse runs on a straight track. So, if we consider the movement in one direction as positive, then the movement in the opposite direction is considered negative.

The area under the v-t graph gives displacement during a particular time interval.

As we mentioned earlier, the direction also matters.

Let us consider the direction away from the initial point as positive.

We SEE that the horse is moving away from the initial point till t=30 min.

After t=30 min, the velocity becomes negative. This means that now the horse starts moving back TOWARDS the initial point.

A nice shaded graph is attached for a much-better visual understanding.

___________________________

Let us first Calculate the Areas of each of the Shaded Parts

Now, we can solve all the QUESTIONS easily.

______________________________

(a) Total Distance travelled by the Horse

To find the total Distance, we consider the positive area of each shaded region.

So,

Thus, Total Distance Travelled by Horse is 1550 metres.

(b) Displacement of Horse till 40 minutes

Here, we are asked Displacement. So the direction of velocity matters. Since negative velocity means that the horse is coming back to the initial point, areas under the graph on the negative SIDE of the Y-Axis indicate negative displacement.

So, the areas on the negative side of Y-Axis are to be considered negative.

So, if Displacement till 40 minutes is s, then:

Thus, The Displacement of the Horse from initial point till 40 minutes is 850 metres.

(c) Average Velocity of the Horse when it travels away from the initial point

Average Velocity is defined as the Total Displacement divides by the Total Time.

So,

Now, we are asked to find the average velocity when the horse is moving away from the initial point.

This simply means that we do not have to consider the time when the horse turns back (velocity becomes negative) and starts to come towards the initial point.

The velocity becomes negative at t=30 min.

Thus, the horse is moving away from the initial point only till t=30 min.

So, we have to find the average velocity in the time interval of t=0 to t=35 min.

Total Displacement in this time interval (say s') is:

So, Average Velocity would become:

Thus, The Average Velocity of the Horse in the given time interval is 35 m/min.

NSEJS Exam is the first exam that gives a taste of the difficulty level of the true Olympiads out there. I had prepared for the NSEJS last year, and qualified with a total of approximately 150 marks.

Firstly, you must have a firm GRIP on Standard 10 CBSE Science as well as Maths as it the absolute basic necessity for this olympiad.

After this, it would be better to get Books for IJSO from any coaching institute. I personally prefer Resonance as the books are easy to understand and it can take you a long way. I, too, prepared from Resonance Material only.

Be SURE to concentrate on Biology, as many take Biology lightly in NSEJS. It is the one subject where you can ANSWER questions quickly and thus save time for Physics and Chemistry numericals.

In the olympiad, the questions of different subjects are mixed together and so, I would advise you to solve the problems in order and not search for the problems of a particular subject. Also, some questions will be purely theoretical and some will be application based and numericals. Do the theoretical ones ASAP as time is also a major factor in this olympiad.

Be sure to manage your time properly and set aside at least 1 hour for filling the OMR Sheet and ATTEMPTING the difficult problems. Filling the bubbles usually takes about half an hour, while quickly rechecking the questions.

Use intelligent guessing and dimensional analysis in the options as many times an extremely difficult problem is made easy by these.

In the end, study regularly and try to make the best of the limited time available to you( a difficult task, I know). Relax and be confident.

Best of Luck!

Please mark it the brainliest and ALL THE BEST FOR YOUR EXAM!!!!!
