What do you know about the following important terms, which we come across every day. (a) Heart attack (b) Cardiac arrest (c) Heart Failure

Text Solution

Verified by Experts

(a) Heart attack: The blood flow to the heart is blocked. A blockage of blood flow to the heart muscle. The heart muscle affected from lack of blood supply.
(b) Cardiac arrest: The heart stops beating and needs to be restarted. Cardiac arrest is an electrical problem, triggered by a disruption of heart.s rhythm.
(c) Heart Failure: Heart Failure occurs, when the heart muscle fails to pump as much as blood as the body needs. It may come to a person suddenly.

Answer the following questions . a. The earth's magnetic field varies from point is space. Does it also change with time ? It so , on what time scate does it change appreciably ? b.

A magnetic field that varies in magnitude from point to point but has a constant direction (east to west) is set up in a chamber. A charged particle enters the chamber and travels undeflected along a straight path with constant speed. What can you say about the initial velocity of the particle? A charged particle enters an environment of a strong and non-uniform magnetic field varying from point to point both in magnitude and direction, and comes out of It following a complicated trajectory. Would its final speed equal the initial speed if it suffered no collisions with the environment? An electron travelling west to east enters a chamber baving a uniform electrostatic field in north to south direction. Specify the direction in which a uniform magnetic field should be set up to prevent the electron from deflecting from its straight line path.
