Tion of light ns equation figure 13.4 and the small-angle approximation imply that de- (equation 13.12, where δ~4gm/尼 4gwb (equation 13.11) and b~ de (from the diagram). the summary claims that together these imply that for the angle θ of images formed by a gravitational lens. exercise 13.6.1. verify that this is true. exercise 13.6.2. the solutions to this equation are θ±-(β± the θ+ solution is clearly outside the einstein ring angle θε. show that meaning that the θ solution is inside the ring. (hint: argue that so, and use this information in equation 13.13, above.) s0, and then

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
