AI Thread Summary
The discussion revolves around a confusion regarding a dynamics problem involving the calculation of an angle using tangent. The user initially struggles to understand how the answer of 36 degrees is derived from the ratio of forces, 5.0 N and 7.0 N. They later realize the issue was due to their calculator being in the wrong mode, specifically not set to degrees. This highlights the importance of ensuring the correct calculator settings when solving trigonometric problems. The conversation emphasizes that simple mistakes can lead to confusion in physics calculations.

Hi again,

we're starting dynamics now and the example problem in the book is very confusing, I don't understand how they got their answer.

tanΘ = opposite/adjacent
= 5.0 N/7.0 N
= 36 degrees

It must be very simple, but I can't get 36 degrees when I try it.

What do I need to input into my calculator to receive this answer?

Oops! I figured it out, I hadn't put my calculator into degree mode!
 
Good to hear it was only something simple. I used to get stuck for ages wondering why my answers were coming out funny.

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 'Struggle to understand the concept of the 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...
