Answer:

0.66

Explanation:

By using the formula

u = v^2 / r g

Where u is coefficent of friction

u = 23.5 × 23.5 / (85 × 9.8)

u = 0.66

It's displacement would be negative

displacement is a vector quantity.

'Backwards', we can assume, would be negative.

Ammonia at 10◦c with a mass of 10 kg is in a piston/cylinder assembly with an initial volume of 1 m3. the piston initially resti

jeyben [28]

Here mass is floating on the piston at equilibrium

So it will have constant pressure always remains constant

So final pressure is same as initial pressure = 900 kPa

now we can say

$\frac{V_1}{V_2} = \frac{T_1}{T_2}$

$\frac{1}{V_2} = \frac{273+10}{273+50}$

$V_2 = 1.14 m^3$

so final pressure is 900 kPa and final volume is 1.14 m^3
