... • Turn the Sun’s velocity direction (keep amplitude) such that the Sun can fall into the BH at Galactic Centre. How accurate must the aiming be in term of angles in arcsec? Find input values from speed of the Sun, BH mass and distances from literature. • Consider a giant star (of 100solar radii, 1 s ...

Pitching Pennies into a Magnet 1 Problem 2 Solution
... If one pitches a penny into a large magnet, eddy currents are induced in the penny, and their interaction with the magnetic field results in a repulsive force, according to Lenz’ law. Estimate the minimum velocity needed for a penny to enter a long, 1-T solenoid magnet whose diameter is 0.1 m. You ma ...

Challenge Problems: Poynting Vector and Energy Flow
... a) What is the direction and magnitude of the electric field E between the plates? You may neglect any fringing fields due to edge effects. b) What is the total energy stored in the electric field of the capacitor? c) What is the rate of change of the energy stored in the electric field? d) What is ...

Complete collapse produces a “black hole.” On the other hand, when the mass is too small or the velocity of implosion is too low the collapse is halted at nuclear or near-nuclear densit ...
