What happens to pendulum clocks in summer?

Because the period is based on the length of the pendulum, an increase in temperature (such as that as occurs in summer) will make the material, normally metal, in the pendulum expand - which is why better clocks often had wooden pendulum rods. Since it is longer its period increases and makes the clock run slower than normal. Numerous inventions were developed to counteract this effect, most taking advantage of the properties of thermal expansion of various materials and how they are arranged in the pendulum.

How many nanoseconds are in 4 seconds?

1 second = 1 billion nanoseconds 4 seconds = 4 billion nanoseconds = 4,000,000,000 = 4 x 109

How many mili seconds in a year?

There are approximately 31,536,000 milliseconds in a year. This is calculated by multiplying the number of milliseconds in a second (1000) by the number of seconds in a year (31,536,000 seconds).

How do I convert Watt seconds to milliwatts seconds?

To convert Watt seconds to milliwatt seconds, you can multiply the value in Watt seconds by 1000. This is because 1 Watt is equal to 1000 milliwatts. So, 1 Watt second is equal to 1000 milliwatt seconds.

Convert Watt seconds to milliwatts seconds?

To convert Watt seconds to milliwatts seconds, you need to multiply by 1000 since there are 1000 milliwatts in a Watt. For example, if you have 5 Watt seconds, it would be equal to 5000 milliwatts seconds.

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.

How does one stop time?

I'm sorry to be the bearer of bad news but this looks unlikely to ever happen.

The frequency of a wave is measured with the unit which is?

Hertz, abbreviated Hz. In unit analysis, this can also be written as 1/s, s standing for seconds.

How long is 500 seconds?

500 seconds is eight and one-third minutes.

What is less than a picosecond?

I'm tempted to reply ½ a pecosecond(!)

However, I think you're asking what is the next description below pecosecond; it is a femtosecond (10−15 second). There are 1000 femtoseconds in a pecosecond.

7200 seconds equals how many hours?

7200 seconds is equal to 2 hours because there are 3600 seconds in an hour (60 seconds x 60 minutes). So, 7200 seconds / 3600 seconds per hour = 2 hours.

What is 31662400 seconds?

31 662 400 seconds = 1.00334234 years 31 662 400 seconds = 12.0401081 months 31 662 400 seconds = 52.3518519 weeks 31 662 400 seconds = 366.462963 days 31 662 400 seconds = 527 706.667 minutes 1 year = 31 556 926 seconds

The unit which frequency is measured?

Frequency is typically measured in hertz (Hz). This unit represents the number of cycles per second in a periodic wave. It is commonly used in various fields including physics, engineering, and music.

Why does your wrist watch lose time?

There could be several reasons why a wristwatch may lose time. It could be due to a low battery, magnetization, external shocks affecting the movement, or even moisture seeping in. Regular maintenance and servicing by a professional watchmaker can help identify and correct any issues causing time loss.

Is Speed time over distance?

Speed is a measure of how quickly an object is moving. Time is a measure of how long it takes for an object to travel a certain distance. Distance is the amount of space between two points. Speed, time, and distance are related by the formula speed = distance/time.

What instrument measures time?

Clocks and chronometers?

watch, water watch and if non techincal then sun and shadow

The instrument used to measure time is called a clock.

Time is measured by clocks.

watch, water watch and if non techincal then sun and shadow

a clock?

clock or watch

A clock.

PW

Einstein recommended a clock.

An atomic clock. See the related link for more information.

As a class, all such instruments are collectively referred to as "clocks".

A chronometer. A clock or a watch. A sundial. An hourglass.

STOP-WATCH

we cannot measure time as it is not a physical quantity... it neither has magnitude nor direction... so it cannot be measured... it can only be seen... hmmm............ a watch is the device used to see time :-)

My eyelids. The length of my droopy eyelids tell me it is bedtime

Clocks.

I use a watch.

Clock, stopwatch, pendulum... the list goes on.

Hm... I don't know, very hard question. I *think* you use something called....Nah it's too crazy of an idea... Alright fine, I'll say it anyway, I think you use some weird alien device called a timer, or stopwatch?

You could either use a watch, a stopwatch, or a clock. Xx livvy xX

How many seconds are in a decisecond?

A decisecond is one tenth of a second. So there are 1/10 seconds in a decisecond, or 10 decisecond in 1 second. There a 10 seconds in a Decasecond.

Is Time Travel Real?

YES the is a way it is a Worm hole. WORM HOLES are rips in the time and space continuum and we could walk through them, if we had the power of a exploding star. So in other words yes if we had a lot of power we could time travel.
So far, nobody has traveled in time. It is doubtful whether anybody ever will.Except one.Who says that he time traveled 8 times and he was at Abraham Lincoln's speech.He's name is Andrew Basiago.We still don't know if it is true

Does salt water boil faster than fresh water?

No, salt water boils slower than fresh water because the presence of salt increases the boiling point of the water. This means that salt water requires higher temperatures to reach the boiling point compared to fresh water.
