The transmutation of a radioactive uranium isotope, 234/92u , into a radon isotope, 222/86rn , involves a series of three nuclear reactions. at the end of the first reaction, a thorium isotope,230/90th , is formed and at the end of the second reaction, a radium isotope, 226/88ra , is formed. in both the reactions, an alpha particle is emitted. write the balanced equations for the three successive nuclear reactions.

Sound energy is produced when an object vibrates. examples are 1- a balloon popping2-a whistle3- a waterfall

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.
