Answer:
It accelerate but will not spin.
Explanation:
If an irregular shaped object is dropped from rest without feeling any form of air resistance it will accelerate without spinning and this is due to the fact that there is no Torque around the center of gravity
The atomic number is how much space is in a object and the mass number is how much it's filled... if I'm not mistaken...
Your answer should be A.km/s does s mean speed?
Answer:
The greater the mass of a body, the greater its inertia
We apply the following equation
T = 2π * sqrt (L/g)
Where g is the gravity = 9.8 m/s^2
L is the longitude of the pendulum (Height of the tower)
T is the period. (T = 18s)
We find L.............> (T /2π)^2 = L/g
L = g*(T /2π)^2...........> L = 80.428 meters
