F = -KX. The proportional CONSTANT k is CALLED the spring constant. It is a measure of the spring's stiffness. When a spring is stretched or compressed, so that its length CHANGES by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction TOWARDS its equilibrium position.

Reflection is the change in direction of a WAVEFRONT at an interface between TWO different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and WATER waves. ... Reflection is OBSERVED with surface waves in bodies of water.

The graph between maximum height attained and the time of flight of a particle THROWN VERTICALLY upward with a variable SPEED  To Find : Shape of Grapha. straight lineb. PARABOLAC. ellipsed. hyperbola​Solution Let say speed = UTime to reach maximum height =  t using V = U + at => 0 = U  - gt=> t = U/gTime of flight = 2t= 2U/gS = ut  + (1/2)at²H = U(U/g)  + (1/2)(-g)(U/g)²=> H = U²/g  -  U²/2g=> H = U²/2g => H = U  . U/2g => H =  UT/4=> H = (U/4) T    T = 2U/gH = U²/2gH ∝ T²Hence Parabolagraph between maximum height attained and the time of flight of a particle thrown vertically upward with a variable speed will be   parabola Learn More:The graph between maximum height attainedbrainly.in/question/27353674

The magnification of a magnifying glass depends upon where it is placed between the user's EYE and the object being viewed, and the total distance between them. The magnifying power is equivalent to ANGULAR magnification (this should not be confused with OPTICAL power, which is a different quantity).I hope it's helpful. PLEASE follow me if it is helpful. ❤️❤️

tion:We KNOW that distance Travelled by uniformly accelerated BODY in n th s is given bySn =u+ 1/2 a(2n−1), where a is the acceleration of the body and u is the initial velocity it is given that S n =4s at n=3⟹4=u+ 25a .............. eq(1)S n =12 at n=5s⟹12=u+ 29a ............... eq(2)SOLVING eq(1) and eq(2), we geta=4m/s 2 and u=−6m/sNow we have to FIND velocity at t=5swe know that v=u+at⟹v=−6+(4×5)=14m/s ⟹S=14×3+1/2 4(3^2)=60mhope this will help you

tion:A drawn arrow has 50 J of stored ENERGY due to the stretch of the bow and STRING. When RELEASED, this energy is converted into kinetic energy such that the arrow will have 50 J of kinetic energy upon being fired. Of course, this ASSUMES no energy is lost to air resistance, friction or any other non-conservative forces and that the arrow is shot horizontally.follow me and mark as brainlist ❤️❤️

Speed of CAR in FIRST 15 minutes = 40 KM/hDistance covered = speed × Time taken60 minutes = 1 hour15 minutes = 6015 hourDistance covered = 240×6015=10kmSpeed of car in next 15 minutes = 60 km/hDistance covered = 60×6015=15km∴ Total DISTANCE covered = (10+15)km = 25 km∴ 25 km is correct

Baking powder is MIXED with the flour. When water is added to this flour to make DOUGH, baking powder undergoes a chemical reaction during which carbon DIOXIDE gas is produced. This carbon dioxide gas gets trapped into the dough and bubbles out which causes the cake to rise making it SOFT and spongy.

During sunrise and sunset, the rays have to travel a LARGER part of the ATMOSPHERE because they are very CLOSE to the horizon. Therefore, light other than red is mostly scattered away. Most of the red light, which is the least scattered, enters our eyes. Hence, the SUN and the SKY appear red.

Kirchhoff’s JUNCTION rule says that the total current into a junction equals the total current out of the junction. This is a statement of conservation of charge. It is ALSO SOMETIMES called Kirchhoff’s first LAW, Kirchhoff’s current law, the junction rule, or the node rule. please mark as brainlest answer please

North eastExplanation:Farmer takes 40 s to move along the boundary. Thus, after 3.5 round farmer will at POINT C of the FIELD. Thus, after 2 min 20 seconds the displacement of farmer will be equal to 14.14 m north EAST from INITIAL position.

Solution : FIRST of all convert the given time 2 minutes 20 seconds into seconds. Total Time = 2 minutes 20 seconds → 2 × 60 seconds + 20 seconds → 120 seconds + 20 seconds → 140 seconds Now, In 40 seconds,Round made = 1 So, In 140 seconds,Round made = (1/40)*140In 140 seconds = 3.5 rounds Thus,the farmer will make three and half rounds of the square field. If the farmer starts from position A,then after completion of 3 rounds, he'll be at STARTING position A. But in the next half round,Farmer will MOVE from A to B,and B to C,so that his final position will be at C. Thus,the net DISPLACEMENT of farmer will be AC. Now ABC is a right ANGLED triangle in which AC is the hypotenuse. [Refer to the attachment] So,∴ The magnitude of the displacement of the farmer at the end of 2 minutes 20 seconds will be 14.143 metres.

Blue light is SCATTERED in all directions by the tiny molecules of AIR in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue SKY most of the time. Closer to the horizon, the sky fades to a lighter blue or white.Explanation:HOPE it helps please MARK me brainliest
