Reasons for the Nationalist upsurge in the 19th century Europe are as follows:

The absolute rulers oppressed the people.
The well-known philosophers and leaders spread liberal ideas and visions.
The French Revolution provided the inspiration to the people to fight for freedom.
The slogan 'Liberty, Equality and Fraternity' became the clarion call for the common people of Europe.
The French army and its soldiers began to carry the ideas of nationalism abroad with the outbreak of revolutionary wars.

An athelete completes two rounds of a circular track 100m long in 20s . Calculate diameter of the track and speed of athlete , supposed to be uniform

Posted by Devikrishna K Saji 3 years, 2 months ago

CBSE > Class 09 > Science

1 answers

Nikhil Bhardwaj 2 years, 11 months ago

The diameter of the circular track is given as 200 m. That is, 2r=200 m. From this radius is calculated as Radius, r = 100 m. In 40 sec the athlete complete one round. So, in 2 mins and 20 secs, that is, 140 sec the athlete will complete = 140 / 40 = 3.5 (three and a half) rounds. One round is considered as the circumference of the circular track. The distance covered in 140 sec = 2πr×3.5=2×3.14×100×3.5=2200 m. For each complete round the displacement is zero. Therefore for 3 complete rounds, the displacement will be zero. At the end of his motion, the athlete will be in the diametrically opposite position. That is, displacement = diameter = 200 m. Hence, the distance covered is 2200 m and the displacement is 200 m.
