Answer:

Explanation:
Given that,
Displacement in North = 11 km
Displacement in East = 11 km
We need to find the approximate displacement of the hiker from the camp. It can be calculated by resultant of two displacement as follows :

Hence, the approximate displacement of the hiker from the camp is
.
It is gravity¿ what is the question?
Pull into the lot of a place that's 24 hours therefor if a office drives by its just a car
When light crosses the interface between a medium with higher refractive index and a medium with lower refractive index, there is a maximum value of the angle of incidence after which there is no refraction, but all the light is reflected, and this maximum value is called critical angle.
The critical angle is given by

where n1 is the refractive index of the first medium while n2 is the refractive index of the second medium. In our problem, n1=1.33 and n2=1.58, so the critical angle is
