Answer:
Height of mirror 0.075 m
width of mirror 0.325 m
Explanation:
given data
wide = 1.3 m
high = 0.30 m
driver’s eyes = 0.50 m
rear window = 1.50 m
solution
we take here height / width of the mirror is
height / width = 
.................1
and
height /width of the window is
height /width = 
.................2
and
distance of eye / window by the mirror is
distance of eye / window = 
.................3
so here
θ = θi = θr ....................4
and tanθ for vertical is
tanθ = 
tanθ = 
....................5
so
h = 
....................6
put here value and we get
h = 0.075 m
and
when we take here tanθ for horizontal than it will be
tanθ = 
tanθ = 
.......................7
so
....................8
put here value and we get
w = 0.325 m
The work performed on an object is the force multiplied by the distance it is moved, provided the movement is parallel to the force. Since that is the case here, we can get the work by W=Fd=1900N x 0.23m = 437J. This energy is used to split the wood.
your question doesnt make sense
Answer:
the pressure fluctuation is LONGITUDINAL
Explanation:
Sound waves are an oscillating movement of air particles, this can be analyzed in two different, but equivalent ways, as an air oscillation and with a pressure wave due to these oscillations.
The expression for the wave is
ΔP = Δo sin (kx - wt)
Therefore, the pressure variation is in the same direction as the displacement variation, consequently the pressure fluctuation is LONGITUDINAL
