Why do radio telescopes have to be very large in order to effectively capture and study radio waves from space?
Radio telescopes have to be very large in order to effectively capture and study radio waves from space because radio waves have long wavelengths and low energy, requiring a large collecting area to gather enough of them for analysis. The larger the telescope, the more radio waves it can collect, allowing for more detailed and accurate observations of celestial objects.

Does a Faraday cage need to be grounded in order to effectively block electromagnetic interference?
Yes, a Faraday cage needs to be grounded in order to effectively block electromagnetic interference.
Why are windmills so large?
Windmills are large in order to capture as much wind energy as possible. The larger the windmill blades, the more wind they can catch and convert into rotational energy to generate electricity. A large size also helps in producing more energy efficiently, making wind energy a cost-effective renewable energy source.
What are things that have lens?
Cameras, microscopes, telescopes, eyeglasses, and projectors are examples of objects that use lenses. Lenses are used to focus and direct light in order to form an image.
How thick does lead need to be in order to effectively stop gamma rays?
Lead needs to be at least 13.8 millimeters thick to effectively stop gamma rays.
Are the bullets sharp?
Yes, bullets are designed to be sharp in order to penetrate targets effectively.
Will New technologies allow astronomers to use X-ray telescopes on Earth's surface?
We had best hope the answer is 'no'. In order to use x-ray telescopes effectively from the earth's surface, you'd have to get rid of the atmosphere.
What planets were founded by telescopes?
Only Uranus and Neptune were not known to the Sumerians, and required telescopes in order to be discovered.
How long does a memoir typically need to be in order to effectively capture the essence of the author's life story?
The length of a memoir needed to effectively capture the essence of the author's life story can vary, but typically ranges from 50,000 to 100,000 words. This allows for a detailed exploration of key moments and themes in the author's life while maintaining reader engagement.

Why are curved mirrors used in some telescopes?
Plane mirrors don't form real images. Concave mirrors and convex lenses do. Without a real image, you have nothing to expose film to, nothing to project onto a screen, nothing to capture on a CCD or vidicon, and nothing to look at with an eyepiece.
What is the correct order of the stages of the GTD method?
The correct order of the stages of the Getting Things Done (GTD) method is: Capture, Clarify, Organize, Reflect, and Engage. First, you capture all tasks and ideas. Next, you clarify what they mean and decide on actionable steps. Then, you organize the tasks into appropriate categories, reflect on your priorities regularly, and finally engage with your tasks effectively.
Why are radio telescopes typically built so large compared with optical telescopes?
Radio telescopes are much larger than optical telescopes because of wavelength. Earth's atmosphere has two major "windows" where it is transparent to photons: 300 nm - 800 nm: optical wavelength window (approximate) 30 mm - 30 m: radio wavelength window (approximate) Even the shortest-wavelengths used by radio telescopes at around 30 mm are still thousands of times longer than the longest wavelengths used by optical telescopes. The wavelength has 2 effects on the size of a telescope: * The angular resolution (in order to distinguish 2 nearby stars, FWHM) depends on the wavelength/aperture ratio. Radio-frequency photons require a wider aperture to focus than visible-light-frequency photons, so radio telescopes *must* be larger to get a reasonable resolution. * A telescope typically requires the collecting area to be aligned within 1/10 of the wavelength it is designed for. Because it is almost impossible to get all the parts of a sufficiently large telescope aligned to within 80 nm, radio telescopes *can* be built much larger.
How do you remove prikles?
A person can remove prickles from their skin by using a large tweezer. A person should pull outwards in order to effectively remove the prickle from inside their skin.

Do tidal tur bines have to be in special place?
These large underwater turbines are placed in areas with high tidal movements, and are designed to capture the kinetic motion of the ebbing and surging of ocean tides in order to produce electricity.
