Homework Statement Does +I effect stabilize or destabilize a carbocation Homework Equations NA The Attempt at a Solution In one way, +I effect tends to increase electron density on the carbocation and hence neutralize the charge and hence would stabilize it. On the other hand, the nature of...

Homework Statement If height of a satellite from the surface of Earth is increased, why does the total energy increase? Homework Equations T.E=K.E + P.E The Attempt at a Solution Here the work done by non-conservative forces is zero. This means that the total mechanical energy of the system...

Homework Statement Two like parallel forces 20N and 30 N act at the ends A and B of a rod 1.5m long. The resultant of the forces will act at a point 1 90 cm from A 2 75 cm from B 3 20 cm from B 4 85 cm from A Homework Equations Torque=Force * Perpendicular distance The Attempt...

Homework Statement What is the difference between a dimensional physical constant and dimensionless physical constant? Homework EquationsThe Attempt at a Solution

Coffee_ said: ↑ You use θ˙=w while θ˙ is something different here as pointed out earlier - we are not assuming uniform circular motion here rememb I suppose omega is constant in pendulum motion. It is equal to (g/L)^1/2

But if I replace the area to be transversed as theta, then is my approach correct? Area traversed by pendulum in theta=(theta * L^2)/2 Magnetic flux=BA=B*(Theta*L^2)/2 EMF=d(B*Theta*L^2)/dt =(BL^2)/2*d(theta)/dt =(BL^2)/2omega =BL^2/2*(g/L)^1/2 But the answer is BL*sin (theta/2)*(gl)^1/2

Homework Statement A simple pendulum with bob of mass m and conducting wire of length L swings under gravity through an angle 2 theta. The Earth's magnetic field component in the direction perpendicular to swing is B. The maximum potential difference induced across the pendulum is Homework...
