as the public need for preventing injuries and deaths from car crashes became known,laws were enacted to mandate the inclusion of seatbelts in almost all passengers vehicles
Based on the average velocity at section 2, and the absolute pressures at both sectors, the average speed at section 1 is 2.226 m/s.
<h3>What is the average speed at section 1?</h3>
Density at P₁:
= (40 + 100) / (0.287 x (40 + 273))
= 1.5585 kg/m³
Density at P₂:
= (10 + 100) / (0.287 x (40 + 273))
= 1.2245 kg/m³
The average speed at section 1 is:
= (Density at P₂ x d² x 25.5) / (Density at P₁ x 9d²)
= 2.226 m/s

Answer:
The heat absorbed portion that is transformed into work is therefore helpful and accessible for our use, hence it is termed as available energy. But the energy or heat which is of no use is termed as unavailable energy.
Explanation:
A engine requires heat from the reservoir and transforms portion of it into function. The extra heat is expelled (generally atmosphere) to cold reservoir. The refused heat can't be equal to zero, as per the 2nd law of thermodynamics. The heat absorbed portion that is transformed into work is therefore helpful and accessible for our use, hence it is termed as available energy. But the energy or heat which is of no use is termed as unavailable energy.

Answer:
Here is the code in Matlab for the function.
I have also attached the m file for function as well as the test run of the code here and screenshot of the result.
Code:
function [ C ] = columnproduct( A, B )
% get the dimesnions of A
sizeA = size(A);
sizeB = size(B);
% check if columns of A are same as rows of B
if(sizeA(2) ~= sizeB(1))
error('matrix dimensions do not match')
end
% initialize resultant matrix
C = [];
for i = 1:sizeB(2)
% concatenating product of matrix A with each column of B
C = [C A*B(:,i)];
end
end
