Answer 1

Cardiac arrest occurs in cases of drowning and electric shock. This means sinoatrial node fails to initiate and propagate impulses to keep heart pumping. Newton`s first law states that if impulse is not propagating itself it needs an external force to start it. Cardiac massage starts the impulse and once it starts it continues.
Second law.
When an intravenous injection is given to a nearly dead person whose blood is not running or circulating the injection has to be given so rapidly that accelaration initiated in blood is maintained.
Third law.
An immobile recumbent bed ridden human presses the bed and the bed presses in return presses with equal force. Waterbeds offer no such opposite reaction and are used for nursing bed ridden people to prevent bed sores.
