The EXACT ANSWER is KNOWN as ACCURATE answer☺

So, magnitude is and dirction of the VECTORS is .EXPLANATION:For v1=2i-3 J and v2 =-6i+5j DETERMINE the magnitude and direction of v1+v2.Since given data in the question is:So, the magnitude of ===for finding the direction we KNOW that the So,So, magnitude is and direction of the vectors is

give me thanksAnswer:The REFRACTIVE INDEX for red light in glass is slightly different than for VIOLET light. Violet light slows down even more than red light, so it is refracted at a slightly GREATER angle. The refractive index of red light in glass is 1.513. The refractive index of violet light is 1.532.

what is the ANSWER of this QUESTION

sorry bro PHOTO is not CLEAR ....in 1st case tension will be = 520in 2nd case tension will be = 410if g=10

DuctilityExplanation: The property of MATERIAL which ALLOWS it to be drawn into WIRE is called DUCTILITY.Hope it is clear for you.Thank You[BRAINLY EXPERT]

Understand what is COMPRESSIVE strength of concrete & how compressive strength is ... M25, 25 N/mm2 ... more than 0.01mm at any point, and they shall be maintained with a permissible VARIATION limit of ... The EQUIVALENT cube strength of the concrete shall be determined by multiplying the CORRECTED cylinder strength by 5/4Explanation:

Due to many reflections and REFRACTIONS through the WALLS of BUCKET.

It is an object to see FAR OBJECTS CLEARLY and MAGNIFIED.

10.65≈10.7≈1110.55≈10.6≈11

take a bottleExplanation:in that bottle FILL cold WATER then add boiled water on that bottle then the bottle get CONTRAST this SHOW atmosphere PRESSURE

tion:A.B = 0......(since they are perpendicular)(3icap +2JCAP + k)(5icap -2jcap +PK) = 015 -4 +P = 0P = -11So, P = (-11) is your answer

give me thanksAnswer:Hope it's clear I assume you know how the formula for potential energy is derivedall I did was1) FIRST WRITE what was given in the question2)then write down what's X+Y in terms of WHATEVER is left and hope that the mass,angular frequency get cancelled out!!!!now put it back in the ANSWER to get your answerthe final answer is

p2 PARALLEL to p1 if you want cross PRODUCT to be ZERO or perpendicular to p1 if you want dot product to be zero.

That's your ANSWER I HOPE it HELPS you

Limitations. The potometer does not MEASURE the RATE of transpiration accurately because not all of the water that is TAKEN by the plant is used for transpiration (water taken might be used for photosynthesis or by the CELLS to maintain turgidity). The potometer measures the rate of uptake of water.Explanation:

I don't KNOW the ANSWER

what are you THINKING for.what I should KEEP the ANSWER.

The force EXERTED UPON SOLID body is called gravitational forceHOPE THIS HELPS YOU❣️❣️✔️✔️✌️✌️

ng to WAVE theory:Light consists of electromagnetic waves which do not REQUIRE a material medium for their propagation. According to particle theory: Light is composed of PARTICLES called photon which travels in a STRAIGHT line at very high speed.

NOExplanation:

Sun is the source of solar ENERGY and hydrogen BOMB

a) Max force ACTING on the car is F = MA = 1000×3.75 = 3750N because it is the MAXIMUM acceleration of car. B) F = MA = here a = 0-15/2 = -7.5m/s then F = 1000×-7.5 = -7500N force 5ć) for 4 seconds there is no force acting because of 0 acceleration. fot the DISTANCE of 60m

The area under a velocity-time GRAPH is a REPRESENTATION of the DISPLACEMENT. If the area is over a time interval, then the displacement during that time interval can be measured by the area under the graph bounded by the time interval. ... BONUS: the slope of a V-t graph is a measure of acceleration.Jun 2, 2018

If the position of a particle isX=sin t + TTHEN it's VELOCITY isSo velocity VS TIME GRAPH is as given in attachment

Pressure can be DEFINED as FORCE upon area. Unit of presure =kgm^-1s2Pressure =force/area

in MAKING residential building parallel circuit is usedit is used because in parallel circuit if one fuse GET lost then ANOTHER fuse will not lost means if one thing is not working properly then another thing will work but in series connection if the FAN is not working than the LIGHT will also not work

It may be POSSIBLE Explanation:because we don't know EVERYTHING about SPACE

dhr6ci4f758th7tu7fh and SWEET POTATO SALAD with

in UNIFORM circular MOTION VECTOR quantity CHANGES

400 J Explanation:1) Since, POINT object is moved  very slowly from A to B .=> KINETIC energy is 0 at point A and B.Since, A and B are at same height from ground.Work done by Gravity = 0 2) Work done by FRICTION l= 200 mLet the work done by tangential force be .3) Now, By Applying Work Energy Theorem ,Hence, Work done by tangential force is 400 J.

In PHYSICS, acceleration is the rate of change of VELOCITY of an OBJECT with RESPECT to time.

Answer:Apply the RELATION - (v / u) = m = hi / ho asAnswer:Apply the relation - (v / u) = m = hi / ho as= (- 5) / 10 = - {(- 30) / u}Answer:Apply the relation - (v / u) = m = hi / ho as= (- 5) / 10 = - {(- 30) / u}=u = - 60 cmAnswer:Apply the relation - (v / u) = m = hi / ho as= (- 5) / 10 = - {(- 30) / u}=u = - 60 cmApply mirror formula asAnswer:Apply the relation - (v / u) = m = hi / ho as= (- 5) / 10 = - {(- 30) / u}=u = - 60 cmApply mirror formula as= (1 / v) + (1 / u)= 1 / fAnswer:Apply the relation - (v / u) = m = hi / ho as= (- 5) / 10 = - {(- 30) / u}=u = - 60 cmApply mirror formula as= (1 / v) + (1 / u)= 1 / f= 1 / (- 60) + 1 / (- 30)= 1 / fAnswer:Apply the relation - (v / u) = m = hi / ho as= (- 5) / 10 = - {(- 30) / u}=u = - 60 cmApply mirror formula as= (1 / v) + (1 / u)= 1 / f= 1 / (- 60) + 1 / (- 30)= 1 / f= 1 / (- 20) = 1 / f or f = - 20 cmAnswer:Apply the relation - (v / u) = m = hi / ho as= (- 5) / 10 = - {(- 30) / u}=u = - 60 cmApply mirror formula as= (1 / v) + (1 / u)= 1 / f= 1 / (- 60) + 1 / (- 30)= 1 / f= 1 / (- 20) = 1 / f or f = - 20 cmHence , the CORRECT choice is b) -20 CM. The (-) ve sign indicates that the FOCAL length lies in front of the mirrorSo option b is correct
