Question

A bullet fired with velocity of 200 metre per second is just able to pierce a wooden plank of thickness 0.8 what velocity is required to the species applying of 0.12 mediatek

Answer 1

Answer:

a velocity of 200/ sec Abel to cut plank of 0.8 thick

so 2(0.4) is pierce by 200 m/ second

0.4 is pierce by 100m/ second

0.12=3(0.4) is pierce by 3(100 m/ second)

it means 300 m/ second

Answer 2

Answer:

Explanation:In physics, the Coriolis force is an inertial or fictitious force that acts on objects that are in motion within a frame of reference that rotates with respect to an inertial frame. ... Newton's laws of motion describe the motion of an object in an inertial (non-accelerating) frame of reference.
