Answer:
n=0.03928 moles
Moles of oxygen do the lungs contain at the end of an inflation are 0.03928 moles
Explanation:
The amount of oxygen which lung can have is 20% of 5 L which is the capacity of lungs
Volume of oxygen in lungs =V=5*20%= 1 L=
Temperature=T=
Pressure at sea level = P= 1 atm=
R is universal Gas Constant =8.314 J/mol.K
Formula:
Moles of oxygen do the lungs contain at the end of an inflation are 0.03928 moles

Answer:
Zero
Explanation:
The work done on an object is given by:
where
F is the force applied on the object
d is the displacement of the object
is the angle between the direction of the force and the displacement
In this problem, you are pushing again a stationary wall: this means that the walls does not move. As a result, the displacement is zero: d=0. Therefore, the work done is also zero: W=0.
Answer:
50C
Explanation:
Given parameters:
Electrical energy = 350J
Potential difference = 7V
Unknown:
Amount of charge = ?
Solution:
To solve this problem, use the expression below;
E = q x v
E is the electrical energy
q is the quantity of charge
v is the voltage
Insert the parameters and solve for q;
350 = q x 7
q =
q = 50C
