ation, also called bio sonar, is the biological sonar used by several kinds of animals. Echolocating animals emit calls out to the environment and listen to the ECHOES of those calls that return from various objects near them. They use these echoes to locate and identify the objects. Echolocation is used for navigation and for foraging (or hunting) in various environments.Echolocating animals include some mammals and a few BIRDS; most NOTABLY microchiropteran bats and odontocetes(toothed whales and dolphins), but also in simpler FORM in other groups such as shrews, one GENUS of megachiropteran bats (Rousettus) and two cave dwelling birdgroups, the so-called cave swiftlets in the genus Aerodramus (formerly Collocalia) and the unrelated Oilbird Steatornis caripensis.Bats use echolocation to navigate and find food in the dark. To echolocate, bats send out sound waves from the mouth or nose. When the sound waves hit an object they produce echoes. The echo bounces off the object and returns to the bats' ears.

ibre ALSO known as PILOT PROBE, is a flow measurement device used to measure FLUID flow velocity. The pilot tube was invented by the FRENCH engineer Henri pilot in the early 18th century and was modified to its modern form in the mid 19th century by french scientist Henry Darcy.

, The PRIMARY coil has to be connected to galvanometer without battery and the SECONDARY coil should be connected to the battery.The secondary coil has move with RESPECT to time because only CHANGING MAGNETIC field can induce current in primary coil

cayA beta particle FORMS when a neutron CHANGES into a proton and a high-energy electron. The proton stays in the nucleus but the electron leaves the atom as a beta particle. When a nucleus emits a beta particle, these changes happen:the mass number stays the samethe atomic number INCREASES by 1the nuclear CHARGE increases by 1

T (ideal gas EQUATION)MASS of gass = Volume X densitym = V x DV = m / Dm = no of moles x Molar mass of gass m = N x M=> V = (n x M ) / DP x (n x M )/ D = n x RTD = PM / RTBrainliest !!! Please

s LAW of universal gravitation states that every particle ATTRACTS every other particle in the universe with a force which is directly proportional to the PRODUCT of their masses and INVERSELY proportional to the square of the distance between their centers

ls NEEDED:tall glass jar,bell,candleMethod:take a glass jar. attach a small bell to the bottom of the cap of the jar. close the jar with the cap. shakethe BOTTLE and note the sound made by bell. now open the jar,place LIGHTED candle in it and close THR jar again. wait for the candle to be extinguished. SHAKE the bottle again. the sound is not produced.the oxygen is taken up by the candle.so the bell does not produce any sound.This proves that sound needs a medium to travel.Hope This Helps!!Mark As Brainliest!!

istance/timeSo TIME = distance/speedT=d/tIn this case the SOUND will reflect BACK from wall so T=2d/tT=2*48/32T=0.3 SHOPE this helps

cause if you throw a stone then after few seconds it will touch the GROUND and LOSE speed and come on 0 but if you throw it slower it will stop early and if you throw STRONGLY then it will TAKE TIME

/r^2If the DISTANCE between TWO charges decrease by half then the force will INCREASE 4 TIMES as force is INVERSELY proportional to r^2

agnetic field exerts a force on a current-carrying wire in a direction given by the RIGHT HAND rule 1 (the same direction as that on the individual moving charges). ... We can DERIVE an EXPRESSION for the magnetic force on a current by taking a sum of the magnetic forces on individual charges.        MARK as brainliest

dation is the process by which the vertebrate eye changes optical POWER to maintain a clear image or focus on an object as its distance varies. ... Mammals, birds and reptiles vary the optical power by changing the form of the elastic lens USING the ciliary body (in humans up to 15 dioptres).

ssion of gamma RAYS does not alter the number of protons or neutrons in the NUCLEUS but instead has the effect of moving the nucleusfrom a higher to a lower energy state (unstable to stable). Gamma RAY emission frequently follows beta DECAY, alpha decay, and other nuclear decay processes.

αVαVIn calculating entropy change for a solid under isothermal pressure change, we used thermal volume EXPANSION coefficient (αVαV). However, in most cases, not volume but linear expansion coefficients (αLαL) are AVAILABLE. In the video, we used the relationshipαVαV=3αLαLHere, let’s derive this RELATIONSHIP.

s second law is often stated as F=ma, which means the FORCE (F) acting on an OBJECT is equal to the mass (m) of an object times its ACCELERATION (a). This means the more mass an object has, the more force you NEED to ACCELERATE it.
