A gas sample is confined within a chamber that has a movable piston. A small load is placed on the piston; and the system is all

owed to reach equilibrium. If the total weight of the piston and load is 70.0 N and the piston has an area of 5.0 × 10 –4 m 2 , what is the pressure exerted on the piston by the gas? Note: Atmospheric pressure is 1.013 × 10 5 Pa.

Explanation:

It is given that,

Total weight of the piston, W = F = 70 N

Area of the piston, a=5\times 10^{-4}\ m^2

Let P is the pressure exerted on the piston by the gas. The force per unit area is called the pressure exerted pressure of the gas. Mathematically, it is given by :

P=\dfrac{F}{A}

P=\dfrac{70\ N}{5\times 10^{-4}\ m^2}

P=1.4\times 10^5\ Pa

We know that the atmospheric pressure is given by :

P_o=1.013\times 10^5\ Pa

So, the pressure is given by :

p=P+P_o

p=1.4\times 10^5+1.013\times 10^5

p=2.41\times 10^5\ Pa

Hence, this is the required solution.

In the graph above, what is the instantaneous speed of the object after the first five seconds?
alexdok [17]

Answer:

D) 25 m/s

Explanation:

In order to solve this problem we must use the following kinematics equation.

v_{f} =v_{i} +(a*t)\\

where:

Vf = final speed [m/s]

Vi = initial speed = 0

a = acceleration = 5[m/s^2]

t = time = 5[s]

After 5 seconds the acceleration is equal to 5 [m/s^2]

Now replacing the values in the equation:

Vf = 0 + (5*5)

Vf = 25[m/s]
