Find the theoretical value for the rotation period τ in s for a pendulum bob with height y = 0.070 m, length L = 0.20 m, y0 = 0.020 m and extension arm length ro = 0.020 m. Use g = 9.801 m/s2.

4. 50x10= 500m/s 5. 52m/s

It's because 3 if it was 10 it wouldn't look right do it goes up to 4d

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.
