Coriolis Coriolis force Force

Click For Summary

The Coriolis force is a result of the Earth's rotation, causing moving objects to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. It is not a real force but an apparent effect observed in a rotating reference frame. The Coriolis effect influences weather patterns, ocean currents, and ballistic trajectories. To calculate the Coriolis force, one can use the formula F_c = 2mvωsin(φ), where m is mass, v is velocity, ω is the angular velocity of the Earth, and φ is the latitude. Understanding the Coriolis force is essential for fields like meteorology and oceanography.

Homework Statement: Find the perpendicular component of N in an inertial frame and in a non-inertial frame

Relevant Equations: newton equation for non inertial frames

I know that the perpendicular force is the Coriolis force, but I don't know how to get it

Do you know what causes the Coriolis effect ? Why it exists. What is the other force ?

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
