Answer:
0.44
Explanation:
Poisson's ratio is:
ν = (3K − E) / 6K
where K is the bulk modulus and E is Young's modulus.
Young's modulus is:
E = FL / (AΔL)
where F is the force, L is the initial length, A is the cross sectional area, and ΔL is the change in length.
E = (20 kg × 9.8 m/s²) (1.7 m) / (π (0.02 m)² × 0.0005 m)
E = 0.530×10⁹ Pa
Bulk modulus is:
K = -ΔP / (ΔV/V)
where ΔP is the change in pressure, ΔV is the change in volume, and V is the initial volume.
K = -(180 atm × 101325 Pa/atm) / (-0.012)
K = 1.52×10⁹ Pa
Therefore, the Poisson's ratio is:
ν = (3(1.52×10⁹ Pa) − 0.530×10⁹ Pa) / 6(1.52×10⁹ Pa)
ν = (3(1.52) − 0.530) / 6(1.52)
ν = 0.442
Rounded to 2 significant figures, the Poisson's ratio is 0.44.
Answer:
The Laws of Badminton
A match consists of the best of 3 games of 21 points.
Every time there is a serve – there is a point scored.
The side winning a rally adds a point to its score.
At 20 all, the side which gains a 2 point lead first, wins that game.
At 29 all, the side scoring the 30th point, wins that game.
A year on Earth is 365 and 1/4 days (rounded). It corresponds to
one revolution of the Earth in our orbital path around the sun.

Answer:
Neither both are correct
Explanation:
The question involves the removal and installation procedure of cable for parking break. The answer for this could be found through the manual procedure for repairing parking break
Technician A is wrong because rear brakes should be adjusted before the parking cable adjustment is being made.
Technician B is wrong because the parking brake lever should be intact and secure at all clicks to allow maximum security. 15 clicks in this case should be the maximum number of clicks for the lever.
