What are the positive and negative impacts of science and technology on human society?
Positive impacts include advancements in medicine, communication, and transportation, improving quality of life and increasing productivity. Negative impacts can include environmental degradation, loss of jobs due to automation, and ethical concerns surrounding privacy and data security. Balancing these impacts is crucial for ensuring that science and technology benefit society as a whole.
What is the most deadly bullet?
DRT ammo. Frangible round, a fine powder surrounded in copper. 9mm,40 s&w,5.56 nato,308 winchester. Made by Dynamic Research Technologies. Nickname "dead right there". It will go through a door, but will not go through a body. When the bullet hits a ballistic material it explodes and the powder goes into everything in about a 5" radius.
How do you make a 348 kilobyte picture 200 kilobytes?
in order to decrease the size of a picture, you must decrease the actual size or use a stronger compression. To reduce the physical dimensions, You can open up the picture using MS Paint, then highlight the entire picture, drag a corner handle to make it smaller, crop it, then presto! To use a stronger compression algorithm you need a more advanced application such as Ownership or The GIMP.
Why do you need or use californium?
Some applications of californium:
- neutron source as Cf-Be source
- neutron source for neutron activation analysis (portable installations)
- neutron radiography
- irradiation for some cancers treatment
- nuclear fuel rod scanning
- neutron source to detect water, petroleum, metals, methane
etc.
How do you get a horse power of refrigerator?
To calculate the horse power of a refrigerator, you would need to know the electricity consumption in watts. One horse power is equivalent to 746 watts, so you can divide the wattage by 746 to get the horse power.
What is the difference between roasting and smelting?
Roasting is a process where ore is heated in the presence of oxygen to remove sulfur, arsenic, and other volatile impurities. Smelting is a process that involves melting the ore to extract metal from it, usually using a reducing agent like charcoal or coke. Roasting is more focused on removing impurities, while smelting is about extracting the desired metal.
Negative impacts of science and technology?
This answer depends on who you ask. Some people may agree certain aspects of technology are negative and others may say they are great. For example, Cell Phones are now able to keep phone numbers saved on them. Some people say this is awesome but in most cases, it deprives people from actually having to remember their numbers which could prove to be negative when all their data is deleted. Other's think that texting has changed our language of English and caused it to morph into another that is grammatically incorrect. Some studies have shown that those who text like this are unable to structure sentences correctly. There are many more example of this but that depends on who you ask.
What is mean by elm conductor?
ELM is a category of the Type of Electrical Conductor/ Cables.
ELM is one & Willow is another Type.
ELM Stands for Electro-Mechanical & Willow is basically a class of Tree Wood.
How much voltage dose it take to kill an average person?
It takes around 100 mA of current at 50-100 volts to be lethal to an average person. Voltage alone is not a good indicator of lethality; it is the combination of voltage and current that determines the danger.
Why does it take so long on gosupermodel.com to upload a picture?
It's not your computer, it's gosupermodel. Gosupermodel is known for taking ages, even with pictures. It's because each and every picture needs to be checked; it can take a day or two unfortunately.
The thrust from the propellers provides the forward force needed to overcome the drag and maintain a constant speed. The lift generated by the wings counters the force of gravity to keep the plane at a constant altitude. As long as these forces are balanced, the plane will continue to fly in a straight path at a constant speed.
What is the difference between radiance and luminance?
Radiance is the amount of light energy emitted or reflected from a surface per unit solid angle, regardless of where it is being viewed from. Luminance, on the other hand, is the amount of light energy emitted or reflected from a surface per unit area as seen from a given viewing angle. In simpler terms, radiance is the total light output, while luminance is how bright it appears to an observer.
Where does all the solar energy go when it is converted?
If the solar panels are conected directly to an engine or motor or any electric item directly the enrgy will go in the electric item and you cannot store the energy the item will start working ,if you connect an battry or capaciter the energy will be stored in that and when ever you want to use it you can use it,and if the solar panel is not connected to any item the energy will go waste.
Is it possible to convert from micro- meter f3 to mili gramm3?
Yes, it is possible to convert from micrometer cubed (µm³) to milligram (mg). However, you need to know the density of the substance in question to make the conversion. Density is measured in units of mass per unit volume (e.g., mg/µm³), and using this information, you can calculate the conversion factor to convert between the two units.
How do you know which LED bulb will replace a common Bulb?
Check the lumens of the common bulb and match it with the equivalent lumens of the LED bulb. Also, consider the color temperature and base type of the common bulb to find a suitable LED replacement. Make sure to check the size and shape of the LED bulb to ensure it fits in the fixture.
Does gravity have an affect on photons?
Yes, photons are affected by gravity. Gravity can cause light to bend around massive objects like stars or galaxies, a phenomenon known as gravitational lensing. This effect has been observed and confirmed through astronomical observations.
In computing, a physical address, also real address or binary address, is the memory address that is electronically presented on a computer address bus circuitry in order to enable the data bus to access a particular storage cell of main memory.
How does a thread work in a CPU?
A thread in a CPU is a sequence of instructions that the CPU can execute independently from other threads. Each thread has its own program counter, stack pointer, and set of registers. The CPU switches between threads to give the appearance of running multiple tasks simultaneously.
What is the definition of oversize particles?
Oversize particles refer to particles in a material that are larger than the desired or acceptable size range. These particles can impact the quality of the material and may need to be removed or reduced in size through further processing or screening.
What scienctist used the S shaped flask?
Louis Pasteur is the scientist who used the S-shaped flask in his experiments to disprove the idea of spontaneous generation. This famous experiment led to the development of the germ theory of disease and the field of microbiology.
Why are washers called washers?
Assuming you mean the flat disc with a hole for screws or bolts. I could not find any clear meaning of how this word came to be. It doesn't really have anything to do with washing (cleaning) anything. There is a reference to an old French word meaning screw. See related link.
How would the life of human beings be if there was no frictional force?
You would not be able to walk. Walking is the friction of your shoe againjst the ground. Without friction, you would not go anywhere. A good example, all though not completely frictionless, is ice. Walking on clean, clear ice is very hard because of the lack of friction.
Show me a picture of an atom model with two electrons?
I'm unable to display images as I'm a text-based assistant. However, a basic representation of an atom with two electrons would have a nucleus at the center (protons and neutrons) and two electrons moving around the nucleus in specific energy levels or orbitals. The electrons would be depicted as small, negatively charged particles orbiting the nucleus at different distances.
Is a solid hologram that you can feel and touch possible?
holograms are projections of light that render a three dimensional view of a person, place, or thing. Compressed light is the only way to make it physically tangible. And in that case all you would feel is a burning sensation as the compressed energy bombards your body at the speed of light.
however, there are ways to add sensation to the hologram using additional sources. a Japanese lab, for example, was able to, in 2009, create a system that allows a person to feel and interact with a hologram using ultrasound to produce tactile feedback and wiimotes to track movement.
