11:10 OZ Quiz 4 Question 10/10 Take a look at the transit light curve on the slide titled "Planetary Transits (Eclipses)" from Lecture 7. Come up with an equation that will allow you to solve for the transiting planet's radius in terms of the star's radius, the normal flux of the star, and the minimum flux of the star during the transit. Then use this equation to solve for the radius of the planet if HD179070's radius is 1.86 times the radius of the Sun. Please give your answer in units of km.

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
