A:
- Black holes are points of high gravitational force in spacetime. The gravitational force is so large that nothing will escape a black hole, not even light.
- Schwarzschild radius is the minimum distance an object should shrink to become a black hole. When an object goes lower than its Schwarzschild radius gravitational collapse takes place. Any mass inside the Schwarzschild radius will be taken in by the black hole formed.
- The Schwarzschild radius also defines the boundary of the black hole called the event horizon beyond which is a point of no return. Schwarzschild radius is given by the following formula,
Here G is the universal gravitational constant, M is the mass of the object and c is the speed of light.

- Astronomers on a planet orbiting 1.500 AU from a star measure the irradiance at the top of their atmosphere as 1700 W/m?. Assume that the irradiance includes all types of radiation produced by the star and that it is emitted isotropically (same in all directions) by the star so that the inverse square law of irradiance can be applied. The current mass of the star is know to be twice the mass of our Sun and that 0.100% of its current mass will be available for hydrogen fusion to helium in the core of the star. What is the current rate of mass conversion in kg/s occurring in the core of the star? Given: 1 AU = 1.495978707 x 10"1 meters, M = 1.989 x 103° kg, c= 2.9979 x 10° m/s aun If the star continues to "burn" mass at this same rate, how long will it be in Earth years until the star runs out of hydrogen fuel in it's core?A magnetic field turns the velocity of a particle but does not change the speed, because the force is always perpendicular to the velocity. Particle accelerators (like CERN,) bubble chambers (to detect and characterize particles,) and mass spectrometers (to identify ions) all rely on this circular motion of charged particles in a magnetic field. In section 26.3, we learn that the radius of the circle made by a charged particle moving perpendicular to a magnetic field is T = mv qB (a) A particle is observed moving to the right when it enters a magnetic field. The magnetic field points into the page. When the particle enters the field, it moves in a clockwise circle. What is the sign of the charge? (b) Explain using physics language why the radius gets larger when the mass increases, and smaller when the charge or field increase. Discuss also why the radius tends to infinity (ie the path becomes a straight line) when the charge goes to zero.
