PART I – ANSWER 6
1ai)
i)propellant
ii)nozzle
1aii)
i)used for communication
ii)used for access geographically dispersed terrains and uneven topography that characterise the nations landscappe
1b)
Given: Object distance for eyepiece, U=3.0cm
Final image distance, V=?
Focal length of eyepiece, F=5.0cm
using the mirror/lens formular
1/f=1/u+1/v
1/5=1/3+1/v
multiplying through with 15v(1.cm)
3v=5v+15
3v-5v=15
-2v=-15/2
V=7.5cm
the final image is virtual and 7.5cm from the eyepiece on the same side of the eyepiece as the object
2)
Given Radius, r=25m
linear velocity, v=20m|s
centripetal acceleration,a=?
Using:
a=V^2/r2
a=20^2/25
a=16m|s^2
6a)
A wave front is the locus of points characterized by propagation of position of the same phase: a propagation of a line in 1D, a curve in 2D or a surface for a wave in 3D. In other words a line or surface in the path of an advancing wave on which all the particles are vibrating in phase is called a wave front.
6b)
i)plane wave front
ii)spherical wave front
