The two objects perform the same task of measuring time and they are hourglass and sundial.
<h3>
What is an hourglass?</h3>
An hourglass is a device used to measure the passage of time.
The hourglass contains two glass bulbs connected vertically by a narrow neck that allows a regulated flow of a substance from the upper bulb to the lower one.
<h3>What is a
sundial?</h3>
A sundial is a horological device that is used to measure time of the day when there is sunlight by the apparent position of the Sun in the sky. Unlike hourglass, its doesn't move.
Thus, the two objects perform the same task of measuring time and they are hourglass and sundial.

Answer:
Explanation:
moment of inertia of man
= mr² , m is mass of man and r is radius of table .
= 53 x 2.9²
=445.73
angular momentum of runner = mvr , v is velocity of runner .
53 x 3.6 x 2.9 = 553.32
angular momentum of turntable
= Iω , I is moment of inertia and ω is angular velocity of table .
= 76 x .2 = 15.2
Total angular momentum = 553.32 - 15.2
= 538.12
Let the common velocity when the runner comes to rest with respect to turntable be ω.
total moment of inertia of the system
= 445.73 + 76
= 521.73
Applying law of conservation of angular momentum
total initial angular momentum = final angular momentum
538.12 = 521.73 ω
ω = 1.03 rad /s .

Explanation:
the president can over turn any ruling made by any governing body not just the supreme court
Fresh water has a variety of different sources on Earth which includes rivers, lakes, streams, rain water, etc.
One of the fresh water sources is a Lagoon which is a permanent shallow body of water which is separated from the larger water bodies by a natural barrier such as reefs or islands.
Reportedly, almost <u>311 plant species</u> are found to be grown in the Atanasovsko Lake lagoon, out of which the Marsh samphire, reed, vicia and sea wormwood are a few to name.
