What will be the time period of a pendulum if it's length is made one fourth of it?
Since the period of a simple pendulum (for short swings) in proportional to the square root of its length, then making the length one quarter of its original length would make the period one half of its original period.Periodapproximately = 2 pi square root (length/acceleration due to gravity)
How many times the pendulum of the clock moves in 30 minutes?
That depends on the period of the clock's pendulum. If we assume it's one second, then it does 1800 cycles in half an hour.
How was a meter defined in 1791?
In the eighteenth century, there were two favoured approaches to the definition of the meter. One approach suggested that the metre be defined as the length of a 'seconds pendulum' (pendulum with a half-period of one second). Another suggestion was defining the metre as one ten-millionth of the length of the Earth's meridian along a quadrant (the distance from the Equator to the North Pole).In 1791, the French Academy of Sciences selected the latter definition (the one related to Earth's meridian) over the former (the one with the pendulum) because the force of gravity varies slightly over the surface of the Earth's surface, which affects the period of a pendulum.
What length of dipole in relation to its wavelength in meters or khz?
There are several kinds of dipole; the most common is the half-wave dipole. Its total length is fairly close to half the wavelength of the design frequency. The length needs to be adjusted slightly to compensate for the thickness of the elements and for end-effects. If the length is wrong by ten or twenty percent it will alter the feed impedance, but have little effect on the gain.
How do you measure an arrow length?
Multiply half its length by 2

What if your grandfather clock's pendulum has a length of 0.9930 m If the clock loses half a minute per day how should you adjust the length of the pendulum?
To adjust the length of the pendulum to correct the time lost, you would need to increase the length of the pendulum slightly. Increasing the length will decrease the time period of oscillation, causing the clock to run slower. You would need to experiment with increasing the length incrementally until the clock keeps time accurately.
If the period of simple pendulum is halved its time period will become. What?
If the period of a simple pendulum is halved, its time period will become half of the original period. This means that it will complete one full swing in half the time it originally took.
A pendulum that takes 5 seconds to make one single swing back and forth has a period of?
The period of a pendulum is the time it takes to complete one full swing back and forth. In this case, the period of the pendulum is 10 seconds (5 seconds for each half of the swing).

The time period of a bob completely filled with mercury is T What will be the time period if the half of the mercury is removed from the bob?
We don't know anything about what the bob is hung with. Is it a bamboo pole ? A steel rod ? A chain or 1/4" aluminum cable ? Is it a thin massless thread ? It makes a difference, because the arc-period of the whole assembly depends on the length between its center of mass and the pivot. Since we don't know anything about the support, we'll assume it to be massless. Also, since we don't know anything about the bob itself, we'll assume it to be a point, with no dimensions, hanging on the end of a massless string. Now the period depends only on the length of the string, and is the same regardless of the mass or weight of the bob. So, removing half of the mercury from the bob has no effect on the period.
Is it true that The length of time required for half of the radioactive atoms in a sample to decay is its period?
No, the length of time required for half of the radioactive atoms in a sample to decay is its half-life, not period. The half-life is the amount of time it takes for half of the radioactive atoms in a sample to undergo radioactive decay. Period typically refers to the time it takes for a complete cycle of a repeating event.
What was used in determining the original length of a meter?
The origins of the meter go back to at least the 18th century. At that time, there were two competing approaches to the definition of a standard unit of length. Some suggested defining the meter as the length of a pendulum having a half-period of one second; others suggested defining the meter as one ten-millionth of the length of the earth's meridian along a quadrant (one fourth the circumference of the earth). In 1791, soon after the French Revolution, the French Academy of Sciences chose the meridian definition over the pendulum definition because the force of gravity varies slightly over the surface of the earth, affecting the period of the pendulum.
What is the length of the grace period for repayment on an unsubsidized loan?
The length of the grace period for repayment on an unsubsidized loan is typically 6 months after you graduate, leave school, or drop below half-time enrollment.
When the K E of a pendulum is at half its maximum value how much P E does it posses?
When the kinetic energy of a pendulum is at half its maximum value, the potential energy it possesses will also be at half its maximum value. This is because the total mechanical energy of the pendulum (the sum of kinetic and potential energy) remains constant throughout its motion.
What is the half angle of conical pendulum of length 1 meter and mass 1 kilograms has a period of 1 second the speed of the particle in its circular motion is 1 meter per second?
T=2pieLsin(theta)/V. 1*1/2*1*pie=sin(theta). sin(theta)=0.1591. (theta)=sin-1(0.1591). (theta)=9.1 degree. half angle=9.15degree
