here is UR ANSWER HOPE it must be HELP full to you

80 metres.Explanation:In velocity-time GRAPH, the area of the graph between the time axis and the curve itself GIVES the distance traveled.Hence, for LAST 8 seconds i.e., from to Distance traveled = Area under the curve and time (x-axis)Distance = Area of ΔBDCDistance = 1/2 × BASE × heightDistance = 1/2 × 8 × 20Distance = 80 metres.

16. (3) 4 Newton19. (1) 100 Newton20. (4) 0 NewtonExplanation:16. If both blocks are moving together, then acceleration of the 2 kg block would ALSO be 2 m/s² as shown in the figure.Now, ∵ F = m × a∴ Force = 2 kg × 2 m/s² = 4 Newton.19. If breaking strength of string is 60 Newtons, then a maximum of 60 Newton of force can be APPLIED on the 3 kg block.Hence, acceleration of 3 kg block when maximum force is acting will beNow, the value of acceleration will be same for both the blocks, because the 2 kg block is pulling the latter one. So,Value of maximum force that can be applied on the system of (2 kg + 3 kg) block will be20. I can't get what this question is SAYING, because without decelerating or accelerating, the car can't take any turn. Also, it hasn't mentioned any circular motion.As no acceleration or retardation is mentioned, and the velocity given is CONSTANT, then there must be no force acting on the body.

bend an object does that object molecules also bend and if we break an object does that object molecules also break...!!➡ YES, If we bend an object does that object molecules also bend and if we break an object does that object molecules also break.Explained in detail :-When a PIECE of metal is bent, atoms need to move. One side of a bend will have atoms trying to move apart (expansion) while the opposite side has them compressing TOGETHER. The added FRICTION will heat the metal as atoms move away from compressed areas or move together in the expansion zones by stretching LIKE putty. If the metal is not maleable enough but more brittle, then atoms will resist moving until they come apart and cause cracks in the expansion zones and may even show some crinkling in compression zones.___________________________________

hat,Initial speed of the CAR, u = 90 km = 90000 mBrakes are applied and BRING the car to rest in 20 secondsTo find,The acceleration of the car.Solution,The change in velocity divided by time taken is called acceleration of an object. It can be given by the FORMULA as follows :So, the acceleration of the car is . Negative SIGN shows that the car is retarding.

The PLUGS having 2 pins are devices which can EASILY handle high voltages.The plugs having 3 pins have 3 wires, a NEGATIVE, a positive and an EARTHING wire because these cannot handle high voltages.

I am not SURE about the QUESTIONEXPLANATION:B OPTION 6V

ocity DECREASE with CONSTANT rate. To keep the rectilinear MOTION of an OBJECT uniform the velocity becomes constant.

Q. 224B option is the correct answer. If n cells are connected in SERIES then their EQUIVALENT emf will be nE.Here VOLTAGE across 3 cells will be 3E. Q. 225Solving 60 ohm and 40 ohm of voltmeter (parallel combination) (60×40)/100 =24 ohmNow voltage DROP in this 24 ohm will be24×emf of source/total resistance in circuit 24×6/24+402.25 volt

D option is the correct ANSWER. Explanation:USING KVL, POTENTIAL of A - (6×2)-12-(9×2)+4-(5×2)= Potential of BPotential of A - potential of B = 12+12+18-4+10= 48 volt

The periodic table is a tabular display of the chemical elements organized on the BASIS of their ATOMIC numbers, electron configurations, and chemical PROPERTIES. ... Elements with the same NUMBER of valence electrons are kept together in GROUPS, such as the halogens and the noble gases.Explanation:

THIS?????????????

Explanation:1). POWER is 1/focal length = 1/ infinity = 0 (as limit of 1/x as x tends to infinity is 0)2). angle of incidence = angle of reflection = 90. this means that LIGHT ray grazes the SURFACE3). 3*10^8 m/s5). when the light passes through the LENS many rays converge at a point and all the heat energy is concentrated on that point only as a result the paper burns DUE to extra heat6). 27). convex mirror10). convex lens

Specific heat: = energy required to CHANGE a UNIT mass of a MATERIAL by 1°C. ... L = latent heat ... Lvaporization = 2.3 X 106 J kg-1. M = 1 kg. DE = energy to heat water to BOILING point

tromagnet is a piece of wire intended to generate a magnetic field with the passage of electric current through it. THOUGH all current-carrying CONDUCTORS produce magnetic fields, an electromagnet is usually constructed in such a way as to maximise the strength of the magnetic field it produces for a special purpose. Electromagnets are commonly used in RESEARCH, industry, medical, and consumer products. An example of a commonly used electromagnet is in security DOORS, e.g. on shop doors which OPEN automaticall

In any part of a circular path the magnitude changes so it is VECTOR quantity. The displacement in a circular path is 0 because U will be there only from where u had STARTED

ies of Electric FIELD Lines-i) Electric field lines originate from positive and terminate at negative.ii) Electric field lines always originate or terminate perpendicular to the surface.iii) The tangent at every point to electric field line gives DIRECTION of electric field at that point.iv) No two electric field lines can ever INTERSECT each other. Since, if they do so there will be two directions of electric field at that point and it is not possible.v) The relative closeness of field lines gives an IDEA about intensity of electric field in that region, closer the electric field line, greater is the intensity of electric field.vi) Electric field lines cannot have sudden break. In a charge free region, field lines are continuous curve existing up to infinity.vii) Electric field lines cannot form closed loops.viii) Electric field lines can never enter a METAL body.ix) Electric field lines try to contract longitudinally i.e. lengthwise which can explain attraction between two unlike charges.x) Electric field lines exert lateral pressure on each other which can explain repulsion between two like charges.

tion:You have seen that white light is DISPERSED into its seven-colour by a prism.why do we get this colour?differentdifferent colours of light band through the different angle with respect to the incident ray as they pass to the prism. the RED light bends the least while the violet the most. the range of each colour emerge by the different path and thus become the distinct. It is the band of the distinct colour that we see in the spectrum. Isaac Isaac Newton was the first to use a glass prism to obtain the spectrum of SUNLIGHT. he tried to split the colours of the spectrum of white light further using the ANOTHER similar prism. however, he could not get any more colours. then he place a second IDENTITY prism in an inverted position with respect to the first prism. This allowed all the colour of the spectrum to pass II prism. I found a beam of white light emergency from the second prism. this observation give the Newton the idea that the sunlight is made up of seven colours.Any light that gives a spectrum similar to that of spectrum is often referred to as White light.

The stars twinkle in the night SKY because of the effects of our atmosphere. When starlight enters our atmosphere it is AFFECTED by winds in the atmosphere and by areas with different temperatures and densities. This causes the LIGHT from the star to twinkle when SEEN from the ground.

eters used in the college laboratory have range of (0–50) mA , (0–100) mA as HIGH as (0–500) mA. The REASON is simple, we do not work with CURRENT higher than this. The VOLTMETERS have a maximum range of (0–20) V.

lectro effect shows particles nature because the are reflected by the articles and reach our eyes making US able to SEE THINGS which reflect light we object that do not reflect light are BLACK for EXAMPLE a black box ve only see it because it is different in light reflection Now example is refraction of light
