Answer:
55 degrees
Explanation:
Given that an air show a jet flies at speed 1500 km/h on a day when the speed of sound is 342 m/s.
From the question above, we can get the below parameters
Object speed (V) = 1500 km/h
Sound speed ( v) = 342 m/s
Convert km/h to m/s
(1500 × 1000)/3600
Jet speed V = 416.67 m/s
Let's first calculate the mash number M.
M = V/v
M = 416.67 / 342
M = 1.2183
Formula for the angle of the shock cone is reciprocal of mash number. That is,
Sin Ø = 1 / M
Sin Ø = 1 / 1.2183
Sin Ø = 0.8208
Ø = sin^-1(0.8208)
Ø = 55 degree
Therefore, the angle of the shock cone is approximately 55 degrees
Answer:
center of mass = −0.50 m
Explanation:
given data
mass m1 = 3.04 kg
distance xm = -8 m
mass m2 = 5.61 kg
distance xM = 3.56 m
solution
we get here center of mass for n mass of system that is express as
center of mass =
......................1
but we have only 2 particle system so we will get
center of mass =
.................2
put here value and we will get
center of mass = 
solve it we will get
center of mass = −0.50 m
Stress = force / area
= 4.8 x 10³ / 1.2 x 10^-4
= 4 x 10⁷ N /m²
YOUNGS MODULAS = stress / strain
= 4 x 10⁷ / 1.2 x 10^11
= 3.3 x 10^-4
INCREMENT OF LENGTH = longitudinal length x intitial length
= ( 3.3 x 10^-4 ) x 4
= 13.2 x 10^-4 m
= 13.2 mm
