Question

Convert $349cm$ into $m$.

Answer 1

Hint: In the CGS system we express gram as the unit of mass, centimeter as the unit of length, and the second as the unit of time. Here the given data is in the terms of the CGS system. One meter is equal to a hundred centimeters. Using this logic to determine the value in terms of meter.

Complete Step by step solution:
Kinematics is the study of the motion of the bodies without considering the cause of motion. These physical quantities are measured by these 3 systems that are F.P.S system (foot, pound, second) C.G.S (centimeter, gram, second) and M.K.S (meter, kilogram, second).In the CGS system, we express gram as the unit of mass, centimeter as the unit of length, and the second as the unit of time

The units of a fundamental physical quantity are called fundamental quantities. The units of a derived physical quantity are called derived quantity. Fundamental quantities and derived quantities are the two types of physical quantities. Examples for fundamental quantity are mass, length, electric current, temperature, amount of substance, and luminous intensity. Area, speed, velocity, etc are examples of a derived physical quantity.

Here the meter is in the FPS system and the centimeter is in the CGS system. Meter and centimeter is a fundamental quantity.
One meter = hundred centimeter
$1cm = {10^{ - 2}}m$
$349cm = \dfrac{{349}}{{100}}m$

$349cm = 3.49m$

Note: Meter is in the FPS system and the centimeter is in the CGS system. Examples of fundamental quantity are mass, length, electric current, temperature, amount of substance, and luminous intensity. The Area, speed, velocity, etc are examples for derived physical quantity. One meter is equal to a hundred centimeter. The units of a fundamental physical quantity are called fundamental quantities.
