I think the answer would be C
Answer:
b) 4781 N
Explanation:
Because there is a redius do this question is talking about the acceleration force which= mv^2/r
so a=15^2/80=2.8125 m^2/s
so the force will be = m.a
F =1700×2.8125=4781.25 N
Answer:
In an earthquake prone area, the things that are needed to be considered for the buildings to stand constant and no cause of damages are as follows-
- The foundation of the building must be made strong, using large amount of concretes so that it can hold the entire load of the building.
- The pillars of the buildings are also should be firmed, rigid, strong and thick.
- The buildings are needed to be construct in such a way that during any seismic event, the forces can be redistributed easily through the body of the building without causing any damage.
- The buildings must be overall comprised of holding high strength and stiffness.
Between both solid and gases, should be liquid.
