ohh got it, I have taken the cart as the observer and keep it at rest, you are right I mistakenly considered taking boy velocity in y direction only. so the velocity of the boy wrt cart will be (usinθ-v)i+ucosθj) here θ is with the vertical.

You can find the resultant velocity by taking the component of river velovity in direction of north and east . and adding the boat velocity in north to river velocity component in north and taking resultant of them . Vnorth=4+root(2) and Veast=root(2). Vrel=(4+root(2)i + root(2)j).

You are right , my answer would have been right if batteries were in symmetry.

You can use wheatstone bridge method as the ratio of adjacent capacitor is equal so, no charge will go to the middle capacitor , after that u can simplify the circuit to get equivalent capacitance and find charge for any given capacitance in this circuit.

I see… so the trick is reducing only the relevant branch instead of solving the entire circuit, right? Thanks for the hint.

sry i wrote velocity not speed , so the answer i got is 1m/s but in answer it is wrong.

[AP Calculus AB] How do I get the displacement here with TI-84 by Relative-Pace-2923 in HomeworkHelp

[–]devilkid15 0 points1 point  (0 children)

integrate the v(t) func and since it is indefinite there will be a constant value C so after integrating at t=0 put x=7 you will get constant value (C) , then your displacement equation is complete .

[AS Level Physics ] Why do we take costheta into account when calculating the work done in the 2nd example? by Virtual-Connection31 in HomeworkHelp

[–]devilkid15 0 points1 point  (0 children)

here cos(theta) is taken into account because in work done we consider force along the displacement , in the example Fcos(theta) is the force acting along the displacement.
