@ 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...
@ 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...

While we define vectors ,we say that the quantity should follow vector algebra,but current doesnot follow vector algebra ,hence it is a scalar quantity.
A=4i+6j A+B=10i+9j so B=6i+3j angle made with x axis=>tan =y/x=3/6=1/2 =tan -1 ½ hence B=6i+3j and angle made with x axis=tan -1 ½
If you arent satisfied then you can ask here,and if you are then please approve the solution.To find direction you should know sense of rotation.
You should not be concerned about such things,take it as granted that these are the angles in a right triangle having side of the form 3n,4n,5n,n N.
Yes,I too agree, the pictures arent clear,the vectors cannot be read ,so please send the picture ones again
The resaultant can never be equal to zero .because two planar vectors can add up,but the third one has none to counter balance,to make it canceled .so it can never be zero if A,B,C non zero vectors.
Bhai, HashLearn is providing unlimited doubt clearing with IIT tutors for a month at Rs. 199. You should try them. Better than waiting here for a response
i^ and i-...
HIi Its an angle of the triangle which is 3-4-5.so the value of cos37 is 4/5
Orthogonal vectors means that dot product is Zero and hence: (2)(3) + (3)(x) + (k)(k) =0........(1) and for 2 nd equation , we have Cross product as Zero. from Both equation we can find ‘k’ and ‘x’
put t^2 = y/3 in z eqn. that is: z = 3t + y/3 and Put t = (z – y/3 )/3 in x = 3t – t^3. to get the paramertic relation in xyz.
First write down the angle b/w the incident and normal and equate it to the angle of normal and reflected light. Assume reflected light be ai + bj + ck. its magnitude would be 1. Therefore,...
@ mintu below arethe reasons 1- both molecules are pyramidal in shape with aloan pairof electron in nitrogen atom .. 2- the orbital dipole moment due to loan pair is in the same direction , as the...
@ shivam i agree than electriccurrent havemagnitude aswell as direction . but it does not obey the vector law of addition and substraction . thatswhy we cannot catagorised it as a vector quantity ....
4 th question is not there in this image. Kindly do upload the correct image.
a linear combination is an expression of the form “(scalar times obect) +(scalar times object) +....+ (scalar times object)”. Of course for such an expression to make sense you need your objects to...
@ raj diffrential equation is besically an equation which involving the derivative of a function . or in otherwords u can say , its a mathematical equation which relate some function with its...
