Example Sentences

Corrective lenses modify the focal length of the eye to alleviate the effects of nearsightedness (myopia), farsightedness (hyperopia) or astigmatism. As people age, the eye's crystalline lens loses elasticity, resulting in presbyopia, which limits their ability to change

The block and tackle system has been used for centuries, with origins dating back to ancient times. However, the modern design and use of block and tackle systems began to emerge during the Renaissance period in the 15th century. It provided a mechanical advantage in lifting heavy loads and has since become a fundamental tool in various industries.

Mauve is a pale purple color with a hint of gray. It is named after the mallow flower, which has a similar shade. Mauve gained popularity in the 19th century and is often associated with creativity and individuality.

No. A US cent minted after 1983 starts out life as a zinc disk that is then "upset"

Convex lenses are commonly used in magnifying glasses, cameras, and telescopes to converge light rays and create a magnified image. They are also used in eyeglasses to correct farsightedness and in projectors to focus light onto a screen.

You can accelerate without speeding up by increasing the rate at which you're changing your speed rather than increasing your overall speed. This can be achieved by pressing down on the gas pedal more slowly but steadily, or using techniques like downshifting in a manual transmission car. The aim is to maximize the vehicle's acceleration while maintaining a steady speed.

Sound energy is used for various purposes, such as communication, entertainment, and detection. It allows us to hear and understand speech, music, and other sounds. In modern technology, sound energy is also used in devices like speakers, microphones, and ultrasound machines.

wax paper, tissue paper, plastic plates, some plastics.. there r lots of them.. ;) stained glass chruch windows .......... give me more answers pleaz!

A stopwatch is a special type of timepiece. It is a handheld watch that is made to time events. It has buttons to start and stop timing an event and will show the amount of time that has elapsed from when it was started to the stop time.

A laundry chute is a metal shaft down a multi-storey building which usually has an opening on each floor and ends in the basement. It is similar to a garbage chute in that it takes the thing it is named after and delivers it to an appropriate location. A laundry chute will generally deliver dirty laundry to the laundry area of the building for washing.

The word graphite is a noun. An example of a sentence using the word would be: While pencils were originally made using lead, they are now mostly made using graphite (which is non-toxic).

an everday example of a translucent object can be your bathroom window; it is not fully opaque as you can see your body figure on the other side, yet you cant see it in detail, therefore your bathroom window is a translucent object.

Translucent means allowing some light to pass through, but not completely transparent. It creates a hazy or blurry effect where objects can be seen but not in detail. Examples of translucent materials include frosted glass or wax paper.

During the chemistry experiment we had to measure the quantity of the liquids careful by using a graduated cylinder.

Objects can be moved without touching them by using various methods such as electromagnetic fields, air or water pressure, sound waves, or even through the use of magnetic levitation. Each method relies on different principles of physics to exert force on the object without direct physical contact.

3M Thinsulate is commonly used in clothing, footwear, and accessories to provide insulation and warmth without adding bulk. It is also used in gloves, hats, and jackets to help retain body heat and keep wearer comfortable in cold weather conditions. Additionally, 3M Thinsulate is utilized in home insulation products to improve energy efficiency and retain heat.

In Sims 2 for PS2, the Metal Detector (not "metal dietike") is used to search for buried treasure in the game world. Simply select the Metal Detector from your Sim's inventory and use it in areas where you suspect treasure might be buried. Follow the on-screen instructions to dig up the treasure once you locate it.

It is the magic of the computer. it makes the image into a reality. IT BENDS TIME AND SPACE. it uses the force. IT ASKS UPON YOU AND YOU ONLY TO SAVE IT. You are the only hope. IT IS TIME. Do you accept your fate, are you ready. THE HOLOGRAPHY ARE WAITING. The time is upon us, lets us RIDE!

An electroscope is used to detect the presence of electric charge on an object by measuring the divergence of its metal leaf strips. It is commonly used in experiments to demonstrate the principles of static electricity and charge transfer. It is also used in testing and troubleshooting of electrical equipment to check for the presence of static charge.

First, most elements have radioactive isotopes. And you can get lots of energy from nonradioactive elements. So radioactivity is not the issue.

Two basic processes for getting atomic energy are fusion and fission. Let's look at fusion.

Fusion is when very light elements like hydrogen and it's isotopes are squeezed together to form helium. The process generates lots and lots of energy. Heavier elements can be fused, too, and all the fusion reactions up through fusion to create the element iron release energy. Stars do this in a process called stellar nucleosynthesis. Elements beyond iron are only created in supernova explosions where the gravitational collapse of certain types of stars results in the fusion of elements to create all the trans-iron elements. The elements thus created include everything up through uranium. The problem is that to cause fusion to happen, you need temperatures on the order of 120 million Kelvins. Generating that is tough, and containing it isn't possible with current technology. So what about fission?

Fission involves the "breaking" of heavy elements into lighter elements, of larger atoms into smaller atoms. You can break any atom, but it takes a lot of energy to do that. And it generally takes more energy than you can get out, which is not practical, except for experiments. Only a few of the very heavy elements are practical energy producers. And they are the radioactive elements that are what we call fissile. They will fission when they are hit by a neutron. It turns out that we can actually set up to do that, and we use uranium or plutonium as nuclear fuel. When we get enough of the element together, it fissions spontaneously and releases both energy, which we can use, and also neutrons, which will go cause other fissions to occur. Basically, only the fissionable isotopes of uranium and plutonium are practical for use as nuclear fuel in fission reactors.

We just can't use any old fuel and create nuclear energy. There are limits imposed by physics and also by our current technology.

Yes, assuming a vessel prepared for travel at the light the headlight would work.

No. Assuming a car could travel at the speed of light, and assume the headlights were isolated to feed the electricity to the bulbs, and assuming the bulb lit up, the light would not project forward through space lighting the way in front of the car, as the light from the headlights would be travelling at the same speed as the car, so it would just be black in front, assuming this is travelling through outer space.

Alkaloids have various uses, including being used as pharmaceutical drugs (e.g. morphine), insecticides, stimulants (e.g. caffeine), and painkillers. They also play a role in traditional medicine and have applications in research and development for new medicines.
