it's very easy. OPEN your NCERT book of science or any REFRESHER or guide of science and read it of CLASS 10 . You will get your answer

In economics UTILITY is the capacity of a commodity to satisfy HUMAN wants. Utility is ... He feels that his GIVEN want is satisfied by the use or consumption of the commodity purchased. Utility ... TRANSPORT services are basically involved in the creation of place utility. In RETAIL trade or distribution services too, place utility is created.Explanation:

In physics, the kinetic ENERGY of an object is the energy that it possesses DUE to its motion. ... The standard unit of kinetic energy is the joule, while the imperial unit of ... The PRINCIPLE in CLASSICAL mechanics that E ∝ mv2 was first developed by .... The kinetic energy of an object is related to its MOMENTUM by the equationExplanation:

a = 9.1 × 10 raised to the power 6 m/second square. EXPLANATION :

v = K√ghExplanation:An object is FALLING freely under the gravitational force. Its VELOCITY after traveling a DISTANCE h is v. object is falling freely  => initial velocity = 0 velocity after traveling a distance h is v=> S = hV = va = g USING V² - U² = 2aS=> v² - 0 = 2gh=> v = √2gh=> v = √2√gh=> v = k√gh  where k = √2 Constant

hey mate here is your answerExplanation:➡️A sharp KNIFE cuts fruits and vegetables more efficiently than a BLUNT knife because, the surface area of the knife is lesser than the blunt knife. ➡️When the surface area is lesser, the sharp knife can easily cut through the fruit or VEGETABLE making it EASY to cut

-When two or more reactants undergoes CHEMICAL REACTION to form a single product, the REACTIONS are CALLED combination reactions i.e. A + B --> AB.Example:- 2NA(s) + Cl2(g) → 2NaCl(s)

tion:Work of WEIGHT = work of normal = 0 because the direction of the FORCE is perpendicular to the DISPLACEMENT. Work of F = Fvt because angle between applied force and displacement is 0 and work of friction = - (mew)mgvt because angle is 180 in DEGREES

ATEIn the first CASE:Force = 6.6 N.Mass = 12 kg.●Force= mass*acceleration.◎So, acceleration = force/mass.a=6.6/12.a=66/120.a=33/60.a=11/20.In the SECOND case:Force=1.2 N.Mass=2.8 kg.By using the same formula:a=1.2/2.8.a=12/28.a=1/2.Since 0.55>0.5.Acceleration produced by a body of mass 12 kg with a force of 6.6 N > acceleration produced by a body of mass 2.8 kg with a force of 1.2 N.HOPE THIS HELPS YOUPLEASE FOLLOW ME ✌️MARK ME AS BRAINLIST

The answer is F = (M +m)gtanθ Explanation:In this case, M and m are moving with the same acceleration "a". Note that a is along horizontal i.e. x-DIRECTION only. For M and m : F - N2Sinθ = ma .....(1) mg - N2Cosθ = 0  => N2 = mg/Cosθ   ......(2) N2 Sinθ = ma ...(3) From equation (2) and (3) we can say that a = gtanθ By SUBSTITUTING equation (3) into (1) we obtain. F = (M +m)a F = (M +m)gtanθ Thus the force that must be applied to M along horizontal direction is F = (M +m)gtanθ .

can chage shape of object can MOVE a object can STOP a object can CHANGE SIZE of a object

tion:OPPOSITION of flow of current is CALLED resistance

he rate of change of velocity.a = (V - U )/tWhere, a is Accelerationv is final velocityu is initial velocityand t is time taken._____________________Types : there are three types if ACCELERATION : POSITIVE accelerationnegative acceleration ( or retardation ) zero acceleration____________________S.I unit ----> m/s²

this is the ANSWER of above QUESTION

tion:Please give all INFORMATION - DIRECTION of forceDirection of displacement (only then we can solve your problem) And if I let that the body is FALLING in the downward direction thenForce= m × G that is 10 × 10 = 100Ndisplacement =1.5mWork done =100×1.5 =15JHope it HELPS Please mark as brainliest

yes EXPLANATION: if the NET FORCE is zero then there will be no acceleration hence the speed of the OBJECT is uniform.

here is your ANSWER THANK you

Specific gravity (relative density) is the ratio of the density (mass of a unit VOLUME) of a substance to the density of a given reference material. ... If the relative density is EXACTLY one then the DENSITIES are equal; that is, equal VOLUMES of the TWO substances have the same mass.Explanation:

criminal cases=according criminal COURT cases by murder, RAPS, robbery,and dacoityExplanation: .it is also called the court of the season judgescivil court=according to civil court it SOLVE MANY problems such as cases by land,divorce,marriage,money transaction

No if a body has ZERO VELOCITY ACCELERATION can't exist Explanation:we know that acceleration is equal to change in velocity with respective to TIME but if the velocity is zero acceleration can't existHence the given STATEMENT is wrong.ʜᴏᴘᴇ ɪᴛ ʜᴇʟᴘs ʏᴏᴜ☺ƒσℓℓσω мє σท iทsτα✌♥

t electric charge of a conductor resides ENTIRELY on its surface. (The mutual repulsion of LIKE CHARGES from COULOMB's Law demands that the charges be as far apart as possible, hence on the surface of the conductor.) 2. The electric fieldinside the conductor is zero.

he RATE of change of velocity.a = (V - u )/tWhere, a is Accelerationv is final velocityu is INITIAL velocityand t is TIME taken._____________________☑️ Types : there are three types if acceleration : POSITIVE accelerationnegative acceleration ( or retardation ) zero acceleration_____________________☑️ S.I unit ---> m/s²

a roughly circular line,ROUTE or movement that starts and FINISHES at the same point is KNOWN as a circuit.an electrical circuit in a device of LOWER resistance than that of a normal circuit is known as short circuit.

mechanical weather is a breaking down of rock into small pieces by PHYSICAL mean.chemical weather is a breaking down of rock as a result of the chemical reaction. I HOPE answer will HELP you lot.

2.5 mExplanation:Method Normal .Note there is a direction CHANGE when ball attains maximum height .The time taken by ball to get to MAX height can be found this WAY : v = u - gt 0 = 75 - 10T t = 7.5 seconds. H = 75*75/20 = 281.25 m Distance travelled in 8th second = Distance travelled in 8 seconds - Distance travelled in 7 seconds So, distance travelled in 0.5 s = 5(0.5)^2 = 1.25 mDistance travelled in 7 seconds =75(7)-5(49)= 35(15-7) = 8*35 = 280So , S8 - S7 = (281.25+1.25-280) = 2.5 m
