Question details

Il. Short answer and calculations 6) (4 pts) Lets make a Black Hole! the speed of light (c 3.00 x 10m/s). To what radius would the Sun (m-2.0x 10 have to be contracted for it to become a Black Hole? Black Holes have escape velocities that are greater than kg) 7) (6 pts) The figure below shows a plot of a wave on a string Le. ytk.1)] as a function of time at location x 0m. The wave is moving to the left at 20 m/s. Write an equation for the wave. Fill the values of all numerical constants. Only x (in meters) and t (in seconds) and sin or cos should remain as symbols in your result. 05 a05 1 15 seci
