Calculating Centrifugal & Coriolis Forces at Rest

AI Thread Summary
Centrifugal force can be calculated for a mass in a rotating frame, while the Coriolis force is dependent on the velocity of the mass relative to the rotating frame. If the mass is considered at rest in the rotating frame, the Coriolis force would indeed be zero. However, if viewed from an inertial frame, the mass is not at rest due to the rotation of the frame itself. Therefore, the context of "at rest" is crucial for determining the Coriolis force's value. Understanding the reference frame is essential for accurately calculating these forces.

Homework Statement
Calculate the values of the centrifugal and the Coriolis forces in a mass of 20g placed at a distance of 10cm from the axis of a rotating frame of reference, if the angular speed of rotation is 10 radians per second.
Relevant Equations
n/a
so I can find the centrifugal force but shouldn't the Coriolis force be 0 because the mass is at rest?

At rest as viewed in which frame?

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
