What do minutes and seconds have to do with longitude and latitude?
Each degree is divided into 60 minutes, each of which is divided into 60 seconds - as for angles in a circle. This can cause confusion since the minutes and seconds do not correspond to their use in measuring time.
The earth rotates through 360 degrees in 24 hours. This means that the earth rotates 1 degree = 60 minutes (angle) in 4 minutes (time).
Hope I got that last bit right!
How long is 1000000 seconds in days or in hours?
1000000 seconds is approximately 11.57 days or approximately 277.78 hours.
Why does an hour have 60 minutes and a minute has 60 seconds?
It is unknown why 60 was chosen. However, it is a very convenient number for expressing fractions. 60 is the smallest number divisible by the first six counting numbers as well as by 10, 12, 15, 20 and 30.
A2. The base 60 system - minutes and seconds, degrees, dates back to the Babylonians who also invented the first writing system - Cuneiform. They also had an interest in astronomy which may have encouraged the degree etc.
What is smaller a yoctosecond or a zeptosecond?
There are 1000 yoctoseconds in one zeptosecond. Therefore, a yoctosecond is oen thousandth the length of a zeptosecond.
As of 2011, yocto- is the smallest SI prefix in use.
yoctosecond means One septillionth (10 -24) of a second.
zeptosecond means One sextillionth (10 -21) of a second
Is an eon the smallest most specific time unit?
No, an eon is actually one of the largest units of time in geology, representing billions of years. The smallest and most specific time unit is typically a second or a nanosecond, depending on the context in which time is being measured.
How are weight and time related?
Weight and time are not directly related. Weight measures the force of gravity acting on an object, while time measures the duration of an event or interval. Factors such as acceleration, speed, and distance can influence how weight and time might interact in a specific situation.
Time affects humans in various ways, including physically with aging, mentally with memory and perception, and emotionally with experiences shaping our sense of time. Time also influences our behaviors, priorities, and decision-making processes, as we navigate deadlines, schedules, and life events. Additionally, the concept of time plays a significant role in cultural, societal, and personal frameworks, shaping our understanding of past, present, and future.
Why is a pendulum not a reliable time standard?
The pendulum is not a reliable time standard mostly because of friction and gravity. To be a reliable time standard, a pendulum would need to form a continuous arc that did not deviate over time. Gravity is always trying to get the pendulum to stop and friction causes the pendulum's fulcrum to resit continued movement. Eventually, a pendulum will stop moving and remain stationary unless acted upon by an external force.
1 nanoseconds make how many megaherz?
Answer: 1000 Megahertz or 1 Gigahertz.
Seconds are one of many ways to measure time intervals; Frequency is the repetition of (other) intervals per unit time. As Frequency is the reciprocal of Time, so Hertz is the Reciprocal of Seconds.
t = 1 / f, f = 1 / t, Hertz = 1 / Seconds, Seconds = 1 / Hertz
A period of 1 nanosecond, 1 / 1,000,000,000 second, corresponds to a frequency of 1,000,000,000 Hertz.
There are 1,000,000,000 nanoseconds in a second. Therefore 1.5/1000000000 is 0.0000000015 seconds
- Ask the question "Quelle heure est-il ?" (What time is it?)
- Say "Il est..." (It is...)
- Say the number of the hour in French (e.g., deux).
- If it's one o'clock, say "heure." If it is 2 - 12, say "heures." Both are pronounced [eur]. For example: Il est trois heures (It's 3:00)
- To say half-past the hour, say "et demie." To say a quarter past the hour, say "et quart." For example: Il est 9 heures et quart (It's 9:15).
- OR to say anywhere from 1 to 59 minutes after the hour, say that number after the hour. For example: Il est une heure dix (It's 1:10).
- OR to say that it is from 1 to 29 minutes before the hour, say the upcoming hour + "moins" + the number (or "le quart" if it is 15 minutes before the hour). For example: Il est 4 heures moins vingt (It's 20 (minutes) to 4).
- OR if it's noon, say "midi" OR if it's midnight say "minuit." You can add on to midi and minuit as in steps 5, 6, and 7. However, half-past is spelled "demi" after midi and minuit.
What is the Pacific time if it's 11PM GMT?
11 AM Australian Central Daylight Saving Time = 12:30 AM GMT
11 AM Australian Central Standard Time = 1:30 AM GMT
11 AM Central Indonesian Time = 3 AM GMT
11 AM Central Africa Time and Central European Summer Time = 9 AM GMT
11 AM Central European Time = 10 AM GMT
11 AM American Central Daylight Saving Time = 4 PM GMT
11 AM American Central Standard Time = 5 PM GMT
How many milliseconds in a nanusecond?
1 millisecond = 1 million nanoseconds
1 nanosecond = 0.000001 millisecond
Why power is measured in minutes not in seconds?
Power is typically measured in watts, which represent the rate at which energy is expended over time. Since power is a measure of energy per unit time, it is commonly expressed in terms of minutes to provide a more practical and meaningful representation of how much work can be done over a certain period. Additionally, using minutes allows for easier comparison and calculation of energy consumption over longer durations.
Depends on where you are at.
10:36 pm. Newfoundland
10:06 pm. Atlantic
9:06 pm. Eastern
8:06 pm. Central
7:06 pm. Mountain
6:06 pm. Pacific
