The four main types of telecommunications cables are twisted pair cables, coaxial cables, fiber optic cables, and wireless transmission media. Twisted pair cables consist of copper wires twisted together; coaxial cables have a copper conductor at the core surrounded by insulation and shielding; fiber optic cables use glass or plastic fibers to transmit data using light signals; and wireless transmission media include radio waves for communication without physical cables. Each type of cable has its own characteristics and advantages based on factors like speed, distance, and susceptibility to interference.

A normal human heart beats 60 to 100 times per minute. However, athletes or individuals with high fitness levels may have lower resting heart rates due to their efficient cardiovascular systems.

To do so, we will simply divide the average heart rate of human being by 60.

Hence, for instance, if we have taken the average heart rate at 70 BPM, then on dividing it by 60, we get 1.17 beats per second. Hence, if a human heart is beating 70 BPM, then it is beating 1.17 beats per second.
