AI Thread Summary
A square plate with a side of 5 cm is rotating around one of its edges, and the angular acceleration is 0.2 rad/s². To calculate the torque, the mass of the plate is needed, which is assumed to be 80g. The formula for rotational inertia is I = 1/2 MR². The calculated torque is 2.0 * 10^(-5) N·m. Participants are encouraged to share their complete problem and work for verification of their solutions.

CHECK OUT THIS PROBLEM

A SQUARE PLATE OF SIDE 5 cm IS ROTATING AROUND ONE OF ITS EDGES. IF THE ANGULAR ACCELARATION OF THE BODY IS 0.2 rad/s/s, FIND THE TORQUE.

ANSWER:2.0 * 10^(-5)
(TWO INTO 10 RAISED TO -5)

You need the MASS of the plate to calculate its rotational inertia I=1/2MR^2.
 
The mass should be given as 80g, right?

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...
