Answer:
Explanation:
The position of each point are the following:
Since the three objects report charges with same sign, then, net force has a repulsive nature. The net force experimented by point charge A is:
Answer:
Explanation:
Diffusion flux of a gas, J is given by
where is permeability coefficient, P is pressure difference and x is thickness of membrane.
The pressure difference will be 10,000 Pa- 3000 Pa= 7000 Pa
At 298 K, the permeability coefficient of water vapour through polypropylene sheet is
Since the thickness of sheet is given as 1mm= 0.1 cm then
Therefore, the diffusion flux is
Answer:
Area of Circle = 78.5398
Surface Area of Sphere = 1.2566 x 10^3 = 1256.6 ft
Volume of Sphere = 33.5103 ft
Explanation:
Please find below the written MatLab script used to solve the problem. I had to define r in each case to solve for the Area of the circle, the surface area and the volume of the Sphere.
r=5; % define r as 5
a=pi*r^2;% calculate the area of the circle
AreaOfCircle=a
r=10; % define r and 10 ft
sa=4*pi*r^2; %Calculate the surface area of the sphere
SphereSurfaceArea=sa
r=2;% define r as 2 ft
vs=(4/3)*pi*r^3;% Calculate the volume of the sphere
VolumeShere=vs
Answer:
Part a : The SI unit of σ is Pascal.
Part b : The pressure is 414.28 psi.
Explanation:
Part a
The equation is given as
As per the dimensional analysis
So the equation becomes
As the dimensions are of pressure so the SI unit of σ is Pascal.
Part b
Pressure in US customary base units is given in psi so
So
So the pressure is 414.28 psi.
