1/2
The unit step function at t=0 is defined to have a value of 1.
a pulse (dirac's delta).
The unit step function is also known as the Dirac delta function. It can be thought of as a function of the real line (x-axis) which is zero everywhere except at the origin (x=0) where the function is infinite in such a way that it's total integral is 1 - hence the use of the word 'unit'. The function is not a strict function by definition in that any function with the properties as stated (0 everywhere except the origin which by definition has a limit tending to 0), must therefore also have an integral of 0. The answer is therefore zero everywhere except at the origin where it is infinite.

kPa is a unit of pressure, kg is a unit of mass
Below code generates unit step function n1=-4; n2=5; n0=0; [y,n]=stepseq(n0,n1,n2); stem(n,y); xlabel('n') ylabel('amplitude'); title('unit step'); It results in a unit step whose value is 1 for time T>0.
YES, unit step function is periodic because its power is finite that is 1/2.. and having infinite energy.

1 (one).
One extra unit of money equals 1 extra unit of utility.

u(t)-u(-t)=sgn(t)
Theta can take units of radians or degrees. However, the sine function itself does not have units. It returns a unit-less value.
Both pulse and impulse are the types of unit step function. In case of impulse the response gains the value for short duration of time and then becomes 0 while in case of pulse it is not neccessary that the value of response become 0 after an interval it may remain constant also.............
