1 st answer is correct but I feel that it's cos⊙ instead of sin . The angle being made by horizontal ground is cos
Hy priya You can get the foot of perpendicular on a line from a point by First of all take a general point on the line in terms of some constant k .. Then get the drs of the line joining the general...
A value decreeses because value right hand screw rule rong order of unit vectors. in parolopiped volume decreeses due to the order ofunit vectors .if corect order of i j k value does not changes but...
Here,To prove: AB+AC+AD+AE+AF=3ADNow,, LHS= AB+AC+AD+AE+AF = AB+AE+AC+AF+AD = AE+ED+AC+CD+AD ( opposite sides of regular hexagon are equal So AB=ED & AF=CD ) = AD+AD+AD =3AD #proved =
it should be km/hr^2 and notkm/hr
Dear student, pls elaborate the question its not clear Thanks
Hello bro gud mrng Badiuddin bro Your solution is wrong Chk this one- Vector A=60i+3j Vector B=40i-8j Vector C=ai-52j Find Vector AB ,BC Vector AB=vector B-vector A Vctr AB=-20i-11j Vctr...
Hii the only condition which is satisfied when a complex number is real is that the sum of the number and its conjugate is a real number OR in other case difference between them would be zero.
hii It totally depends how the equation of plane is given rather it can be assumed as finding out distance between a line and a point. The normal to both the planes is given in the equation . You just...
Hii assume the 3 vertices of the triangle be postion vectors as a,b,c and having done that you can find out the altitudes of the triangle passing from the vertex and slope perpendicular to the base on...
Hiii You can assume a , b , c to be any vectors in 3D space . And after wards apply the dot and cross product wherever required. It will lead you to the RHS . But if you want to prove it then assume...
Time taken =√2h/g = √2*4.9/9.8= 1Given range = 10U*t= 10U*1 = 10U = 10It leaves plane with velocity 10 m/s
Work done is product of displacement and the component of force in the direction of displacementWork done= 5(2i-2j-k)+4(I+2j+2k)+3(-2i+j-2k) = 8i+j-3k =√74
@ guna the physical quantity which have both direction and magnitude are known as vector . example – velocity , displacement etc . vector obeys some special laws of addition . it have 2 laws –...
Dear pallavi we know that O'G =2GO where G is the centroid of triangle let a point D between B and C So, OD =(OB+OC )/2 now OA + OB + OC = OA + 2OD we know that G devide the point A and mib point of...
given tht direction ratios are (1,1,1) and perpendicular distance as given 3√3 so,, d/√(1²+1²+1²) =3√3=> d=9 so the required equation is x+y+z=9
@ pranjal u need to do the following things to enhance the prep for jee . 1- make a proper time table and always stick to it . 2- do practice as much ques as u can but dnt loose time in practicing the...
hi dear salma.. if u know the answer to the qusetion..then you can do that how much you know about that queston...otherwise... dont live it … because of something is better than nothing....
@ zaki physical chemistry generally consists of the numericals part , and criticalk thinking part where physics will be applied to solve the problem , so, here below are the chapters which comes under...
@ VANSH mostly aquaous solution of alkali hallides are extracted when ethers are added . so, in this case alcl will be eliminated . the answer turns out to be licl and nacl . but if the answer will be...
@ vansh 2 unpair electron will be their , sulpher have 16 electron .so, its outer electronic configuration will be 1s2 , 2s2 , 2px2 , 2py2 , 2pz2 , 3s2 , 3px2 , 3py1 , 3pz1 . so, it have 1 unpair...
