Who is invented compass​

Physics
2 answers:
sweet-ann [11.9K]3 years ago
8 0

Answer:

A Chinese Geomancer

 Explanation:

The compass was invented in China during the Han Dynasty between the 2nd century BC and 1st century AD where it was called the "south-governor" or "South Pointing Fish" (sīnán 司南). The magnetic compass was not, at first, used for navigation, but for geomancy and fortune-telling by the Chinese.

However, it is believed Flavio Gioia first invented the refined compass, and a monument has been erected in Almafi Italy to honor his invention. The magnetic compass was probably developed by combining the wind rose and the lodestone. From this device, it is supposed the compass rose evolved.

Mass of rock  = 5kg

Height = 2m

Unknown:

Work done  = ?

Solution:

The amount of work done is given as:

 Work done  = Force x distance

 Work done = Weight x height

  Work done  = mgH

Now insert the parameters and solve;

 Work done  = 5 x 9.8 x 2 = 98J

  • Initial velocity=20m/s
  • Final velocity=0m/s(As the car stops)
  • Acceleration=-8m/s^2
  • Distance=s=26m

We need to verify the thrid equation of kinematics here

\\ \tt\longmapsto v^2-u^2=2as

\\ \tt\longmapsto 20^2=2(-8)s

\\ \tt\longmapsto 400=-16s

\\ \tt\longmapsto s=|400/-16|

\\ \tt\longmapsto s=25m

The squirrel has a good luck ,Car gets stopped just 1m away from the squirrel .

Write some harms of friction.
Veseljchak [2.6K]

Answer:

Friction produces unnecessary heat leading to the wastage of energy. The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects. Forest fires are caused due to the friction between tree branches. However, friction can also cause problems in a car. Friction between moving engine parts increases their temperature and causes the parts to wear down. Friction can be both harmful and helpful, so it may be necessary to decrease or increase friction.
