Answer:
is 26.25 N
Explanation:
Given that: 
= 20 N, 
= 17 N.
This implies that the two forces are acting at right angle to each other. Thus applying the Pythagoras theorem, we have;
= 
= 
= 
= 
= 26.2488
= 26.25 N
The net force is 26.25 N.

Answer:
The correct answer will be option-C
Explanation:
The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.
The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.
This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.
Thus, Option-C is the correct answer.
