this is the ANSWER of your QUESTION

because of SCATTERING of LIGHT .. .........

Here 10M is VERTICALLY upwards that means it is in z AXIS in upward direction and not north. This is an IMPORTANT point do clear it.so final Displacement is= √ x^2 + y^2 + z^2= √ 8^2 + 10^2 + 6^2= √200= 10 √2 m.Hope it helps!

what is your QUESTION I cannot UNDERSTAND

The orignal price is 1350 rupees.Explanation:Let us consider that the orignal amount is "X" now the 12% of "X" would be equal to 12 × X ÷ 100 which is reduced from the orignal amount "X" and the FINAL amount is 1188, thus we write it in the form of equation .:X - (X /100)×12 = 1188=> X - 12X /100 = 1188taking LCM on LHS(100X - 12X)/100 = 1188=> 88X/100 = 1188X = (1188 ×100)/88 = 1350

your ANSWER is 20kgExplanation:here F=100N ,t=4s v=20m/sthrrefore ACCELERATION a= v/t a=20/4 a=5m/s^2Therefore F=ma100=m*5m=20 KG

Static, sliding, and rolling friction occur between solid surfaces.STATIC FRICTION-Static friction is friction between two or more solid objects that are not moving relative to each other. For example, static friction can prevent an object from sliding down a sloped surface. The coefficient of static friction, typically denoted as μs, is usually higher than the coefficient of kinetic friction. Static friction is considered to arise as the result of surface roughness features ACROSS multiple length-scales at solid surfaces. These features, known as asperities are present down to nano-scale dimensions and result in true solid to solid contact existing only at a limited number of points accounting for only a FRACTION of the apparent or nominal contact area. The linearity between applied load and true contact area, arising from asperity deformation, gives rise to the linearity between static frictional force and normal force, found for typical Amonton-Coulomb type friction.SLIDING FRICTIONSliding friction (also called kinetic friction) is a contact force that resists the sliding motion of two objects or an object and a surface. Sliding friction is almost always less than that of static friction; this is why it is easier to move an object once it starts moving rather than to get the object to begin moving from a rest position.ROLLING FRICTIONRolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface.Another cause of rolling resistance lies in the slippage between the wheel and the surface, which dissipates energy.ADVANTAGES OF FRICTIONFriction plays a vital role in our daily life. Without friction we are handicap.1. It is becomes DIFFICULT to walk on a slippery road due to low friction. When we move on ice, it becomes difficult to walk due to low friction of ice.2. We can not fix nail in the wood or wall if there is no friction. It is friction which holds the nail.3. A horse can not pull a cart unless friction furnishes him a secure Foothold.4. We can write on a paper or on a board.5. Friction helps in applying the brakes.6. It helps in walking on floor.7. Coffee mug stays on the dashboard8. Shuffling across a carpet to shock someone9. Draging of atmosphire with earth is possible10. Helps to pevents the life on earth by burning astroids.DISADVANTAGES OF FRICTION Despite the fact that the friction is very important in our daily life, it also has some disadvantages like:1. The main disadvantage of friction is that it produces heat in various parts of machines. In this way some useful energy is wasted as heat energy.2. Due to friction we have to exert more power in machines.3. It opposes the motion. 4. Due to friction, noise is also produced in machines.5. Due to friction, engines of automobiles consume more fuel which is a money loss. 6. Machine efficency is decreased: energy input is lost to heat7. Getting shocked by doorknobs8. Rug burn9. It counteracts movement and so it takes more energy to move, it can cause unwanted heat (e.g. in machine parts), and it wears things out like shoes.10. Forest fires are caused due to friction between branches of TREES HOPE THAT HELPEDPLZPLZPLZPLZFOLLOW MEHAVE A GREAT DAY.....MARK THIS BRAINLIESTTHANK IT....BYE♡♡♡

not PROPER QUESTION PLS SEND it again

Explanation:In a SIMPLE HARMONIC oscillator, the energy oscillates between kinetic energy of the mass K = 12mv2 and POTENTIAL energy U = 12kx2 stored in the spring. In the SHM of the mass and spring system, there are no dissipative forces, so the TOTAL energy is the sum of the potential energy and kinetic energy.

as C=AE°/Dit DEPEND on SIZE and THICKNESS and ALSO on MATERIAL....c′=kc

e SPEED is INCREASE and it is squared.hence the speed increase and everything is constant.so the KINETIC ENERGY increase.

force=mass×acceleration=500×20=10000newton

Heya MATE.....Let the speed of the man be X m/sspeed of the train= 200 m/sDistance = speed x time200m (length of train)= (20-x) x 20 s Let the speed of the man be x m/sspeed of the train= 200 m/sDistance = speed x time200m (length of train)= (20-x) x 20 s When train and man are in OPPOSITE direction200 m = (20+10) tso t=20/3 seconds HOPE it helps.......

(B) ACCELERATION is RIGHT ANSWER

An ORDER of magnitude is an exponential change of plus-or-minus 1 in the value of a QUANTITY or unit. The term is generally used in conjunction with power-of-10 scientific NOTATION. ... Thus, 23.15 is one order of magnitude smaller than 231.5, which in TURN is one order of magnitude smaller than 2315.Explanation:

o the ATTACHMENT ❤️

F/122) M2 = F/3.8Combining, m2/M1 = 3.1578Ergo, m2-m1 = m1*(3.1578- 1) = 2.1578m1 a(2-1) = 12/2.1578 = 5.56 m/s² a(2+1) = 12/(3.1578+1) = 2.886 m/s²

a = G*M/R², where a is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance, which, at sea level, the average radius of the Earth is 6.376 * 10^6 m. For a height h, the acceleration due to gravity is: a = GM/(R+h)^2 … so it decreases as h grows. Explanation:What you need to notice about these equations -The strength of Earth’s gravitational field on a body gets weaker as you move FARTHER away from the Earth’s center. Gravity is considered a weak force. -Because of the magnitude (10^6) of these variables, h MAKES LITTLE DIFFERENCE until it too, is a sizable number.   Thank you !
