What Does [N30.0'E] Indicate in Navigation Terms?

AI Thread Summary
The discussion centers on the navigation term [N30.0'E], which indicates a direction of 30 degrees east of north. A pilot needs to calculate the correct heading to reach a lake located 250 km in that direction while accounting for a westward wind of 40 km/h. The correct heading to maintain a direct flight path is determined to be N20.5'E, with a ground velocity of 227 km/h towards the lake. Clarification is sought on whether the calculations are based on a flat Earth or a spherical model, emphasizing the complexity of navigation in varying conditions. Understanding these directional terms and their implications is crucial for accurate flight planning.

Hey i would appreciate if some1 is able to help me out here... this is the question:
A pilot wants to fly her plane to a lake that is 250.0km [N30.0'E] from her starting point. The plane has an air speed of 210.0km/h, and a wind is blowing from the west at 40km/h.
a) Calaculate in what direction should she head the plane to fly directly to the lake
b) If she uses the heading determined in (A), what will be her velocity relative to the ground?
It seems simple but the answer to the question is not the same one that i am getting. (Answer in the book is a) N20.5'E
& the answer to (B) is:
b) 227 km/h [N30.0'E]
Any help would be appreciated!

Is this on a flat Earth or on a sphere?

What does [N30.0'E] mean? 30 degrees north of east? or 30 degrees east of north?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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...
