Ct is a sophisticated medical diagnostic method that can give detailed information about injury and disease within the body (a) if a high-level sportsperson were to hurt their arm a ct scan might be used to determine details of the injury. what kind of information can be obtained from a ct scanner? how? (1 mark) (b) in the table below, the mass absorption coefficients and densities of different materials are presented mass absorption coefficient| density (cm2/g) material (g/cm3) borosilicate glass (pyrex) soft tissue 15.050 2.23 5.379 1.00 water 5.329 1.00 (i) if 10 kev energy x-rays travel through these materials with an initial intensity of 1 w/cm2, what is the intensity of x-rays emerging from 5cm thick samples of each of these materials? |(2 marks) (ii) compare the properties of these materials with reference to x-rays. is there any point using these x-rays to try to measure the difference between these materials? justify your answer with an explanation (1 mark) (iii) how would it be possible that the mass absorption coefficient of each material be different for other x-ray energies?

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
