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

the variable is usually a number, and the conditional loop has nothign to do with movement/ where something is located
Answer:
The pH of the solution will be equal to 5.46
Explanation:
The dissociation reaction of HCl is equal to:
HCl → H+ + Cl-
To solve the exercise we must first convert the µmoles to moles using the following conversion factor:
3.5µmoles x 
= 3.5x
moles
Assuming a liter of solution, we can calculate the molar concentration by:
M = 
Replacing:
M = 
= 3.5xmoles/L
As this acid dissociates completely, the concentration of protons and chloride will be equal to 3.5xmoles/L
The pH will be equal to:
pH = -log[H+]
Replacing:
pH = -log[3.5x] = 5.46
Answer:
Explanation:
The cylinder head sits on the engine and closes off the combustion chamber. The gap that remains between the cylinder head and the engine is completed by the head gasket. Another task of the cylinder head is to ensure the constant lubrication of the cylinder
Answer and Explanation:
The heat engine are used for converting the heat energy into mechanical energy .When heat energy is converted into mechanical energy then this mechanical energy are used to do the useful work. Heat engine working based on the three process that are head addition , expansion and heat rejection.
