The relative velocity {\displaystyle {\vec {V}}_{B\mid A}} is the velocity of an object or OBSERVER B in the rest FRAME of another object or observer A. Velocity is a QUANTITY that designates how fast and in what direction a point is moving.Explanation:HOPE it helps you

tion:An inelastic collision is a collision in which there is a loss of kinetic energy. While MOMENTUM of the SYSTEM is conserved in an inelastic collision, kinetic energy is not. This is because some kinetic energy had been TRANSFERRED to something else. ... Such collisions are simply called inelastic collisions.

The SHAPE of the magnetic field PRODUCED by a horseshoe MAGNET is revealed by the ORIENTATION of iron FILINGS sprinkled on a piece of paper above the magnet.Explanation:

s law of Universal GravitationNewton's law of universal gravitation is usually STATED as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their MASSES and inversely proportional to the square of the distance between their centers.DevelopmentThe existence of the gravitational CONSTANT was EXPLORED by various researchers from the mid-17th century, helping Isaac Newton formulate his law of universal gravitation. Newton's classical mechanics were superseded in the early 20th century, when Einstein developed the special and general theory of relativity.FatherSir Isaac Newton contributed SEVERAL key principles to the studies of science and mathematics in the fields of optics, calculus, and mechanics. Among Newton's most renowned work is the theory of universal gravitation--or gravity--which holds that a universal force of attraction exists between all matter.

These structures range in size from small sheds to industrial-sized BUILDINGS. A miniature greenhouse is KNOWN as a cold frame.

Friction is the force resisting the relative motion of SOLID surfaces, fluid layers, and material elements SLIDING against each other.[2] There are several types of friction:Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction ("stiction") between non-moving surfaces, and kinetic friction between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities (see Figure 1).Fluid friction DESCRIBES the friction between layers of a VISCOUS fluid that are moving relative to each other.[3][4]Explanation:please mark me as brainliest

The displacement after half a circle WOULD be 2r[2 * radius}EXPLANATION:This is because when a stone tied[CONSIDER it as object]to a string is MADE to move round a circle the distance between the string being held by our hand and the stone is counted as the radius[starting position]. MOVING it half a circle round means the shortest distance[displacement]between starting point and the position[half a circle or final position], which is 2 times the radius[r]. hence the answer is 2r

As the DROPLETS collide, or more humidity condenses onto the SURFACE of the droplets, they become too large to be supported by air currents, and fall as rain. For the rain to all fall at once, something would have to support it until all the water had MERGED into one mass. The WIND doesn't supply that much lift.Mark me brainliest!

It is very simple. Let me start from the clouds. Many think cloud is water vapor but actually, it is a mass of tinny water droplets. These water droplets are pulled by the gravity but remain floating due to the buoyancy of the air. Now, with convection, the cloud moves up and the tinny water DROPS collide with each other,generating much bigger droplets. When droplets unite together, their weight increases so much that they are pulled by the gravity. When they are pulled by the gravity, they do not come in a straight line, rather due to wind and turbulence in air, their movement is chaotic. With the result, they collide with each other and break into new droplets. Also, due to the SURFACE TENSION of water, only droplets up to about 2 mm or so are able to remain in spherical shape and beyond that they are oblate. The horizontal size is much more than the vertical size. The DOWNWARD motion is opposed by the wind.Thanks to nature that rain comes by striking each other otherwise, nothing would have survived on earth, if a raindrop of just 5 mm in diameter was coming straight from the cloud height say just 2 km above the surface of earth. For those who wish to know that the maximum terminal velocity of raindrops is < 10 m/s. Please calculate the velocity if the drop was coming from a height of 2 km? Also, thanks to nature, even if we throw a bucket of water at cloud height, it will get fragmented into millions of droplets for the benefit of entire ecosystem on earth.Explanation:Hope it HELPS you

Mass=10 KG Height = 50 cm =0.5 m W= mgh =10*10*0.5 =50 J Since kinetic energy=potential energy by LAW of conservation of energy

Given :  Initial speed=u= 0 m/s time=t=5sec Case 1) distance travelled = height of BRIDGE=h m From second equation of MOTION: s=ut+1/2at²h =0xt +1/2 9.8 X 5 x5h =122.5m ∴The height of the bridge from water level  is 122.5m Case II) Distance travelled in 4sec = (1/2x9.8x4x4) =16x4.9 =78.4 m Distance travelled in last second : =Distance travelled in 5sec - distance travelled in 4 sec=122.5 -78.4=44.1m ∴The distance covered by STONE in the last second is 44.1m

The atomic number is the number of PROTONS in the NUCLEUS of an ATOM. ... The number of protons determines how MANY electrons surround the nucleus, and it is the arrangement of these electrons that determines most of the chemical behavior of an element.
