1 answers

Yogita Ingle 4 years, 4 months ago

km/hr = 1 km/1 hr = 1 × 1000 m/60 × 60 sec = 1000/3600 m/sec = 5/18 m/sec

So, we say that to convert km/hr into m/sec, we multiply by 5/18.

40× 5/18 = 11.11 m/s

Bronion motion

Posted by Harsh Kumar 4 years, 4 months ago

Meghna Thapar 4 years, 4 months ago

Brownian motion is caused by the random buffeting of small particles by atoms and molecules which are constantly moving. The particles must be small enough to move by brownian motion. Brownian motion, also called Brownian movement, any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations. It was named for the Scottish botanist Robert Brown, the first to study such fluctuations (1827).

SI unit of velocity?

Posted by Amandeep Bhasin 4 years, 4 months ago

Aniket Raj 4 years, 4 months ago

SI unit of velocity is metre per second because velocity of a body in the distance travelled by it per unit time in a given direction we know that the distance travelled in a given direction is known as displacement so we can also write the definition of velocity in terms of displacement velocity equal to definition of velocity in terms of displacement velocity equal to displacement by time taken so SI unit of velocity is metre per second the direction of velocity is same as the direction of displacement of the body
