Explain why, when you have a fever, you have to keep a thermometer in your mouth for a certain length of time in order to read your correct temperature.

Because the certain period of time is needed for reaching the right temperature. After the first seconds of placing the thermometer under the tongue, readings will continue to increase and the F (or C) symbol will flash during measurement.

Explanation:

# Checking our body’s temperature with a thermometer is an easy way to see if a fever is present. There are many different types of thermometers we can use to measure temperature. When using any kind of thermometer, we need to follow the instructions that come with the thermometer in order to read the correct temperature.

# The question above is about how to use a digital thermometer, which can be used three different ways, including oral, rectal, axillary. To keep a thermometer in the mouth (place it under the tongue) for a certain length of time is the oral way to use it. This method is used for adults and children 4 and over who are able to hold thermometer in mouth. So, we call this kind of thermometer as "digital oral thermometer".

# Using a digital oral thermometer, we should follow the followings:

1- Wash the hands with soap and warm water.

2- Use a clean thermometer, one that has been washed in cold water, cleaned with rubbing alcohol, and then rinsed to remove the alcohol.

3- Do not eat or drink anything for at least five minutes before taking the temperature because the temperature of the food or beverage could make the reading inaccurate. It is neccesary to keep the mouth closed during this time.

4- Place the thermometer tip under the tongue.

5- Hold the thermometer in the same spot for about 40 seconds.

6- Rinse thermometer in cold water, clean it with alcohol and rinse again.

# In the instruction N5: Readings will continue to increase and the F (or C) symbol will flash during measurement. Usually, the thermometer will make a beeping noise when the final reading is done (usually about 30 seconds). If we are keeping track, record the temperature and the time.

And the MOST IMPORTANT THING is: we should add a degree to oral reading for the most accuracy. Rectal temperatures are considered most accurate indication of the body’s temperature.

We all use gps today, even if we don't drive yet. i bet you have been in the car with a parent and they have asked you to get out your phone to find a specific location. in your car, on the phone, you are using a very sophisticated technology. gps satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. gps receivers take this information and use trilateration to calculate the user's exact location. essentially, the gps receiver compares the time a signal was transmitted by a satellite with the time it was received. the time difference tells the gps receiver how far away the satellite is. now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map. what type of signal is utilized by the gps satellite?

The lights used by mark watley (played by matt damon) during the film the martian seem to be metal halide lamps. metal halide lamps are filled with vaporized mercury and metal-halogen compounds. when an electric current is passed through the lamp, the tube begins to glow a bright white/blue color. if you were to pass this light through a prism to separate the individual light frequencies, you would see a rainbow just as you would if using natural sunlight because of the complexity of the metal halide gas and the vast amount of possible electron transitions. (the study of light in this way is known as spectroscopy and allows astronomers to know exactly what atoms compose distant stars, simply by looking at the light they emit. the spectral lines an atom produces uniquely identifies that atom just like a fingerprint uniquely identifies a person. the momentum equation and energy equation that we have used above can be combined to give the following equation: c = e p where again p is the phonon momentum, e is the photon energy and c is the speed of light. when you divide the photon energy found in #6 by the photon momentum found in #4, do you get the speed of light? (if not, check your work for questions #4 through #6). yes no
