A cylinder of gas is compressed by a piston from an initial volume of 125 liters to a final volume of 90 liters. The compression
ololo11 [35]
Since the process occurs at constant pressure, the work done by the gas on the piston is given by
W=p \Delta V = p (V_f - V_i)
where
W is the work
p is the pressure
V_f is the final volume
V_i is the initial volume

In our problem, we have
V_i =125 L = 125 \cdot 10^{-3}m^3
V_f = 90 L = 90 \cdot 10^{-3} m^3
W=-104 J (where the negative sign means the work is done by the piston on the gas)

We can re-arrange the previous equation and use these values to find the pressure:
p= \frac{W}{V_f - V_i}= \frac{-104 J}{90 \cdot 10^{-3} m^3 - 125 \cdot 10^{-3} m^3}=2971 Pa

A fall thrown vertically upwards with a speed
Anna71 [15]

Answer:

Height of tower = 480 meter

Explanation:

Given:

Initial velocity = 20 m/s

Time taken to reach ground = 8 second

So,

Final velocity = 0 m/s

Acceleration due to gravity = 10 m/s²

Find:

Height of tower

Computation:

s = ut + (1/2)(g)(t)²

s = (20)(8) + (1/2)(10)(8)²

s = 160 + (1/2)(10)(64)

s = 160 + (10)(32)

s = 160 + 320

s = 480 meter

Height of tower = 480 meter
