Assuming the simplest conditions (ie (1) the pendulum pivot is frictionless, (2) no air resistance for the bob's travel, etc...):
This is a problem best solved by considering the situation from an ENERGY standpoint (and not from, say, a velocity and force standpoint).
Under energy conservation (the assumption of "simplest conditions" above gives us this), the total energy (TE) remains constant. The two components contributing to the total energy in this situation are: (1) the kinetic energy (KE) and (2) the potential energy (PE).
So, TE = KE + PE
We know (hopefully) that the (simple) formula for the PE of a mass in earth's gravity is:
PE = mgh where m is the mass, g is the force of earth's gravity and h is the height above SOME (any) reference point.
We also know that the pendulum's KE at the top of its swing (in this problem, the top of the swing is when it's horizontal) is zero.
For simplicity, we'll set the reference point for all height measurements at the bottom of the pendulum's swing (ie one meter below the pendulum's point of attachment to the stand/ceiling/support whatever).
Putting all the info. above together:
At the START, TE = PE + KE = PE = mgh = 0.1 kilograms * 9.8 m/s^2 * 1 meter
= 0.98 Joules
Now at the BOTTOM of its swing, TE = PE + KE,
BUT PE is zero at the bottom of the swing (because h is zero)
AND we just computed TE above as 0.98 Joules
SO, at the swing bottom, KE = TE = 0.98 Joules
At the 30 degree from vertical mark,
Trigonometry tells us that the height, h, at 30 degrees is 1 meter - cos(30)*1 meter
= (1 - 0.8660) meters = 0.1340 meters
SO here the PE is: PE = mgh = 0.1 kilograms * 9.8 m/s^2 * 0.1340 meters
= 0.1313 Joules
AND going back to find the KE, TE = KE + PE gives us 0.98 = KE + 0.1313,
implying that KE = 0.8487 Joules
Through evolutionary theory. According to evolutionary theory all modern lifeforms evolved from earlier, ancestral forms, ancestry they share with other forms. In the case of humans, such ancestors would have included earlier, now extinct species of ape and yet earlier primates.

Christan Huygens invented the pendulum clock in 1659. Christan huygens is a Dutch Scientist.The invention of the pendulum clock is credited to Christian Huygens who developed working versions in the mid 1650's AD. A couple decades earlier, Galileo came up with designs for a pendulum clock, though it was not completed.

As we mentioned earlier, a CRT can be used to graphically and visually plot an electronic signal,such as a sine wave. This is done by using a second set of deflection plates called VERTICAL-DEFLECTION PLATES

You can calculate aggregate saving by using the power of compounding. The earlier you start saving, the faster you can aggregate or compound your existing savings in the bank.
Actually the simple pendulum isn't used much any more. But in earlier times the periodicity of the pendulum was used to drive the gears of mechanical clock; like the old grandfather clock that stood in the home of the rich back in the 1800s. Because the period of a pendulum was fairly stable and constant, it made an excellent source of energy for clockworks. But now clocks are driven by much more precise means, like crystals and atomic disintegration. And this is true in general; pendulums have been replaced by more precise means of providing periodic energy.

-- Read your watch at the beginning, and write down the time. -- Read your watch at the end, and write down the time. -- Subtract the earlier time from the later time. The difference is the duration.
The answer depends on earlier than WHAT? Earlier than the nineteenth century? Earlier than 6 BC? Earlier than 5,000,000 BC? In the last case, the answer is NONE!
Yes. Earlier (comparative of the word early) can be an adjective or an adverb:Examples:Let's go to the earlier movie. (Earlier is an adjective modifying the noun movie.)Brian called earlier, but you weren't here yet. (Earlier is an adverb modifying the verb called.)
We did not have it earlier.
