Time it take for light to get to Mercury?
it takes about 3-4 minutes for light to travel to mercury
How long does the light from the sun take to get to mercury?
The mean distance from Mercury to the Sun is 58 million km, or approximately 3.2 light-minutes. It takes the Sun's light from 2 1/2 to 3 3/4 minutes to reach Mercury. The orbit of Mercury varies from 28,583,820 miles (46,001,200 km, 0.307499 AU) to 42,760,839 miles (68,816,900km, 0.466697 AU)
What are the 3 types of thermometer?
The three main types of thermometers are liquid-filled thermometers (mercury or alcohol), digital thermometers, and infrared thermometers. Each type measures temperature differently but all provide accurate readings.
Calculate the time it takes light from the sun to reach Mercury?
Mercury's average distance from the sun is about 58 million kilometers, or 58 billion meters. Light travels at a speed of about 300 million meters per second. Divide the distance by the speed of light to get the time needed, and you end up with about 193.3 seconds, or about 3.2 minutes.You can check this answer to make sure that it makes sense by remembering that light from the sun takes roughly 8 minutes to reach Earth. Earth and Mercury are both terrestrial planets, Mercury is closer, and 3 minutes and 8 minutes aren't wildly different times, so the answer looks reasonable.
What is an instrument that measures changes in air pressure using liquid mercury?
Any liquid can actually be use in a tube (barometer) to measure air pressure, but there are various advantages in using mercury for the purpose. 1. Mercury is a shiny liquid (a liquid metal) so it can be easily seen through the glass tube. Other liquid like water are transparent. 2. Mercury is very heavy. So only 76cms of it rises in the tube. Had you been using water for the purpose, you would need a glass tube as long as 55ft. 3. Mercury does not stick to the glass surface inside, so the reading obtained is much more accurate and precise. Remember: Water droplets stick to glass.
How long do you keep a mercury thermometer under you tongue?
You should keep a mercury thermometer under your tongue for 3-4 minutes to ensure an accurate reading.
How long should you keep the thermometer under your tongue?
You must hold your mouth closed and keep the thermometer in place for a certain period of time. If you have a digital thermometer, it will tell you when it's "done". If you are using an old "mercury thermometer", the thermometer must stay under the tongue for at least a minute to 2 minutes.NOTE: Mercury thermometers are being phased out. The mercury inside is highly toxic and you should dispose of all mercury thermometers by taking them to a recycling center that handles that. DO NOT THROW IT IN THE TRASH. Mercury is poisonous to every living thing.UPDATE: GERATHERM offers MERCURY FREE thermometers that work the same as the mercury ones. They are supposed to be safe.
How long should you leave a mercury thermometer in place?
You should leave a mercury thermometer in place for about 3 minutes to ensure accurate reading. Make sure the thermometer is at the correct position under the tongue, armpit, or rectum, depending on the type of thermometer being used. Always follow the manufacturer's guidelines for accurate temperature measurement.
How long should you leave a mercury thermometer in patient's mouth?
A mercury thermometer should be left in a patient's mouth for about 3 minutes to get an accurate reading. Make sure the patient keeps their mouth closed during this time to ensure an accurate measurement.
How do you properly use a mercury thermometer?
To properly use a mercury thermometer, shake it down to below 96 degrees Fahrenheit, place it under your tongue for about 3 minutes, then read the temperature at eye level. Be sure to clean it with alcohol before and after each use.
Why do you use mercury thermometer?
As tempertature rises, the Mercury in the thermometer expands, causing it to go up. As temperature decreases, the mercury in the thermometer contracts, causing it to go down on the scale. However, mercury thermometers are very dangerous if it breakes and gets on your skin. so it it reccomended to use an electric thermometer. these thermometers use thermoelectric current to measure temperature. ergo. they are safe if they break cheers <3 -Eli
What are three different sorts of thermomenters?
Mercury thermometer: uses the expansion of mercury to measure temperature. Digital thermometer: uses electronic sensors to quickly and accurately measure temperature. Infrared thermometer: measures temperature by detecting the infrared energy emitted by an object.
How many minutes to take temperature?
Taking a temperature typically takes about 1 to 5 minutes, depending on the method used. Digital thermometers generally provide a reading in about 1 to 2 minutes, while infrared thermometers can yield results almost instantly. However, if using a mercury thermometer, it may take around 3 to 5 minutes for an accurate reading. Always follow the manufacturer's instructions for the specific thermometer being used.
How long should an axillary thermometer be left in?
An axillary thermometer should be left in place for about 3-5 minutes to ensure an accurate reading.
What are the four kinds of thermomether?
1. Alcohol or spirit thermometer 2. Mercury thermometer 3. Liquid crystal thermometer 4. Quartz thermometer 5. Reversing thermometer 6. Resistance thermometer
Time it take for light to get to Mercury?
it takes about 3-4 minutes for light to travel to mercury
How do you take temperature with a clinical thermometer?
Step 1: Clean your glass thermometer with isopropyl alcohol before using it, then dip the tip into some cool water, or wipe with a tissue, to remove the taste of the alcohol. Step 2: Shake down your glass thermometer until the mercury line is below 96.6 degrees F. Step 3: Slide the tip of the thermometer under one side of the tongue, well into the back of the mouth. Step 4: Close your mouth around the thermometer using your lips - don't clench the glass thermometer with your teeth. Breathe through your nose, with your mouth closed. Step 5: Leave the thermometer under your tongue for 3 full minutes. Step 6: Remove the thermometer and hold it under a bright light, so you can see how high the mercury has risen. An arrow will point to the normal temperature, which is 98.6 degrees F.
