What are 3 uses of infrared radiation.

Answers

Answer 1

Answer: Remote controls
Security systems
Communication systems

Answer 2

Answer:

uses of infrared radiationUsed in night vision devices to observe animals or people using the phenomenon called infrared illumination. The observant will not know that they are being observed.Used in astronomy to observe objects that are blurred and hidden by the interstellar dust. Infrared imaging process is used here.Used in astronomical telescopes that are equipped with infrared sensors and these telescopes are used to detect distant planets that are in the dusty regions of space, as they cannot be viewed using a normal telescope. They are also used to detect objects that have had a high red-shift (shifting of wavelength towards the red end of the spectrum).Used in infrared lamps (lamps that emit infrared radiation) and these lamps are used for drying paint, wallpapers and printing inks, to keep food warm, in heaters that are used during cold weather and in heat treatments in the field of medicineUsed in infrared lasers that produce infrared beams that can be used to read information on compact discs.Used in Infrared imaging devices that are used to obtain images of infrared radiation that are reflected or produced by objects, for example, heat insulation in buildings, sources of thermal pollution, mapping vegetation on the earth’s surface.Used in the chemical industry to determine molecular structure and composition of substances by studying their infrared emission or absorption.

D. Slowly and steadily apply your breaks.

Explanation:

When a person is being tailgated by another vehicle there's a risk of accident, due to the difference of speeds. When someone is being tailgated by another vehicle, it's because they vehicle doesn't work, cannot move by itself, so one vehicle impulse another.

To avoid any accident, the vehicle that's being tailgated must apply breaks often and slowly to try to maintain the same constant distance and speed than the other vehicle. This constant distance is what avoid accidents.

Therefore, the right answer is D.

Answer:

Your answer here is D

Explanation:

Slowly pressing your breaks will help ensure you are not hit by the other car. If they hit you its their fault. Hope this helps :)!

What is an example of Brownian motion in everday life

Answers

Flower pollen on water or smoke in a glass box.
Both show random motions of the flower pollen and smoke due to the random motion of the water and air molecules.Jan Ingenhousz had described the irregular motion of coal dust particles on the surface of alcohol in 1785. Nevertheless Brownian motion is traditionally regarded as discovered by the botanist Robert Brown in 1827. It is believed that Brown was studying pollen particles floating in water under the microscope. He then observed minute particles within the vacuoles of the pollen grains executing a jittery motion. By repeating the experiment with particles of dust, he was able to rule out that the motion was due to pollen particles being 'alive', although the origin of the motion was yet to be explained. Consider a large balloon of 10 meters in diameter. Imagine this large balloon in a football stadium or any widely crowded area. The balloon is so large that it lies on top of many members of the crowd. Because they are excited, these fans hit the balloon at different times and in different directions with the motions being completely random. In the end, the balloon is pushed in random directions, so it should not move on average. Consider now the force exerted at a certain time. We might have 20 supporters pushing right, and 21 other supporters pushing left, where each supporter is exerting equivalent amounts of force. In this case, the forces exerted from the left side and the right side are imbalanced in favor of the left side; the balloon will move slightly to the left. This imbalance exists at all times, and it causes random motion. If we look at this situation from above, so that we cannot see the supporters, we see the large balloon as a small object animated by erratic movement. Now return to Brown’s pollen particle swimming randomly in water. One molecule of water is about .1 to .2 nm, (a hydrogen-bonded cluster of 300 atoms has a diameter of approximately 3 nm) where the pollen particle is roughly 1 micrometer in diameter, roughly 10,000 times larger than a water molecule. So, the pollen particle can be considered as a very large balloon constantly being pushed by water molecules. The Brownian motion of particles in a liquid is due to the instantaneous imbalance in the force exerted by the small liquid molecules on the particle. Okay, I hope that'll answer your question!
