Define pulse?

Q. Define pulse and blood pressure.

Q. Pulse rate can be defined as

Q. A travelling wave pulse defined as $y=\frac{10}{5+(x+2t{)}^2}$. In which direction and with what velocity is the pulse propagating?

Q. The time required for a pulse to change form 10 to 90 percent of its maximum value is defined as _____________.

Q.

A wave pulse moving to the right along the x-axis is represented by the wave function $y(x,t)=\frac{2.0}{(x-3.0t{)}^2+1}$ , where x and y are in centimeters and t is in seconds. (The maximum pulse height is defined as maximum displacement along y-axis). Then
