There are 1000 grams in a kilo. So, this means 3 kilos contain 3000 grams, which, if divided in packs of 50 grams, we will have 60 units of 50 grams.
Robots can move using various mechanisms, including wheels, tracks, legs, and propellers. These mechanisms are powered by motors or other actuators that provide the necessary force and motion for the robot to navigate its environment. Additionally, some robots can also move by crawling, hopping, or flying, depending on their design and intended tasks.
What is a microwaves wave length?
The wavelength of microwaves typically ranges from 1 millimeter to 1 meter in length. The exact wavelength depends on the frequency of the microwaves, with lower frequencies having longer wavelengths and higher frequencies having shorter wavelengths.
No, although Edison was apparently often jealous of Tesla, I don't believe he had anything to do with this. Tesla's first experiment with transmitting electricity through the ground caused a 130 foot lightning bolt, and then set the local generator on fire. His attempt at building a full scale version ran out of funding, and he could not get more because he had lied about its purpose in the first place, claiming it was for communication.
A pendulum swings due to the force of gravity acting on it as it moves back and forth. When the pendulum is released from a raised position, gravity causes it to fall and start swinging. The length of the pendulum and the angle at which it is released also affect how it swings.
A sphygmomanometer consists of three main parts: a cuff to wrap around the arm, a pressure bulb to inflate the cuff, and a pressure gauge to measure blood pressure readings. Some models may also have a stethoscope to listen to the pulse.
The trains carrying the nuclear material have been dubbed "glow trains" by anti-nuclear groups. A train carrying nuclear waste somehow derailing or colliding with another train and thus causing a massive disaster, possibly wiping out Las Vegas or some other city, while en route to the Yucca Mountain Federal Waste Repository.
Sound energy is a form of mechanical energy produced by vibrations that travel through a medium, such as air or water. These vibrations create changes in air pressure that our ears interpret as sound.
Why physics is the basis of technology?
Physics provides the fundamental principles that govern the behavior of matter and energy in the physical world. Technology relies on these principles to design and develop new devices, tools, and systems that improve our quality of life. Understanding physics can help engineers and scientists innovate and create new technologies to address various challenges and advance society.
A constant volume thermometer measures temperature by keeping the volume of the gas inside the thermometer constant. As temperature changes, the pressure of the gas inside the thermometer also changes, which can be correlated to the temperature. This type of thermometer is commonly used in laboratories and for precision measurements.
Is current a vector or a scalar?
Definitely current is a SCALAR. Current density, of course, is a vector quantity
Current = charge / time
Both charge and time are scalars
Current density = current / area
Here area is a vector quantity
Hence scalar product of current density and area give scalar quantity i.e. current.
So electric current is a scalar
Of course we assign +ve and -ve sign to currents. It is not because of direction as we do incase of vectors. But it is only algebraic sign.
Differeniate science from technology?
Science is knowledge about a subject.
Technology is gadgets.
ANSWER: Science is the method in which nature is described. How the universe works, and what that means to us is the thrust of science. By asking these questions scientists have and will continue to discover certain truths about the universe. The technology built is based upon the certain truths that have all ready been discovered. When we were still Cavemen the technology was low tech and based upon the scientific knowledge of that time cavemen used fire, fashioned weapons, and carved art in stone using low tech tools. Technology. As our understanding of fire expanded so did our use of fire in technology. As our understanding of weaponry and biology and even physics expanded so did our use of weapons as technology. The predictions of a future filled with hover crafts and nano technology doesn't exist yet because the science hasn't made the necessary discoveries to fulfill these prophesies.
A nuclear bomb is more dangerous than an equivalent TNT bomb because?
Nuclear weapons arvastly more danerous than regular TNT because not only do they emit high levels of deadly radiation, which can last for decades, but even the most simple of atomic weapons, such as those used at Hiroshima and Nagasaki have a yield equivilant to twenty thousand tons of TNT (20 kilotons). Also, if used enmasse, nuclear weapons could cause a "nuclear winter", which would be the result of the dust and smoke created by nuclear blasts, which would fill the atmosphere and block out sunlight, plunging the earth into a long-lasting (I'm not sure exactly how long, but it would be more than years for sure, maybe even more than decades), radioactie winter.
The electromagnetic force is one of the fundamental forces in nature, responsible for interactions between charged particles. It encompasses both electric and magnetic forces, which are manifestations of the same fundamental force. It plays a crucial role in a wide range of phenomena, from holding atoms together to generating light and other electromagnetic waves.

What are the three major divisions in science?
Biology, the study of animal and plant life.
Chemistry, the study of chemicals and medicine.
Physics, the study of the laws of physics, magnetics, electricity, and other things affecting the Earth.
There are other uncommon branches of Science, but they all fall under these three categories.
The actual answer is that the three main divisions of science are Physical Science's, Biological or Life Science's and Social Science's.
Can I just Point Out that whoever was the dick that wrote that^ 'an' goes before a vowel, 'H' being the exception occasionally used. :P -Batman
Answer:
There are no stupid questions, although it isn't very difficult to search using Google.
Copper, Lead, Zinc, and Aluminum are all non-magnetic metals.
Who are the fathers of physics?
The "fathers of physics" typically refer to notable figures in the history of physics who made significant contributions to the field. Some commonly recognized fathers of physics include Isaac Newton, Albert Einstein, and Galileo Galilei. Each of these scientists made groundbreaking discoveries that revolutionized our understanding of the physical world.
What is the use of metal cylinder?
Metal cylinders are commonly used for containing gases under pressure, such as in compressed gas cylinders for welding or in gas storage tanks for various industrial processes. They are also used in hydraulic systems, for storing liquids in hydraulic machinery. Additionally, metal cylinders are used in automotive applications, such as in engine cylinders for combustion.
What is the relationship between physics and technology?
To this question, we must understand the role of physics and engineering. The reader must forgive the gross oversimplification in the following descriptions - the purpose of this is to provide only the broadest of understandings of the disciplines involved.
.
Physics is the science of modeling the universe around us, and then examining and manipulating those models so that we better understand how the universe works. For example, physics has a conceptual and mathematical model for gravity that lets us predict at what velocity a body must travel to remain in orbit around the earth at a given altitude in space. The model also tells us what will happen to the orbital parameters should the orbiting body speed up or slow down, and thus lets us accurately "what if" questions about the real universe using only our model.
Engineering is the discipline of applying physics models to the real world in order to accomplish a desired result. Engineers build rockets and satellites based on the principles of physics, and by doing so, are able to launch a satellite into a stable orbit. By successively refining the processes by which they translate models of physics into real-world applications, engineers can progressively make more effective, more efficient, and safer rockets and satellites, even while the physical models remain constant.
.
Technology is the byproduct, or perhaps the result of physics and engineering. Technology is the resulting rocket, propellant, satellite, microcircuit, and so on. Only through engineering could those technological products have been developed, and only through physics could the engineers have understood how to begin to develop them.
.
So we can see physics is very important to technology, because without it, we would lack the understanding we require about our universe to eventually develop technology.
Technology is everything that people invent or design to improve life from the old inventions and to lead to a new age. The 6 simple machines that Archimedes invented all have to do with physics. Without them, we wouldn't have the best technology that we have today, like cars, factories, wells, etc. Without factories, we'd be slower on building everything else, like electronic toys, handheld video games, computers, etc.
Technology is nothing without Physics. Every technology involves Physics. Like for instance is the LRT's, computers, cellular phones, or any electronics uses electricity which is involve in the study of Physics. The computer will not also work without the magnets and loops of wires which are also involve in the study of Physics.
Physics and Technology are very much related. Physics deals with understanding of the natural world, while technology aims to apply this understanding into the man-made world. technology might even be considered as the offspring of Physics. The world wide web, laser, superconductors and semiconductors that form the foundations of our modern technology were all invented by physicists.
How is physics related to technology?
Physics is the general analysis of nature, conducted in order to understand how the world and universe behave.
Technology is the usage and knowledge of tools, techniques, and crafts, or is systems or methods of organization, or is a material product (such as clothing) of these things.
So, in short, physics is one of the ways to acquire the knowledge to create technology. And technology is one of the application of physics.

How physics related to technology?
Physics is everything that people invent or design to improve life from the old inventions & to lead to improved societies. Without physics a piece of technology and science is missing. Physics is a science that impacts all other sciences. Physics leads to new products and new technology. In fact all of the sciences are related to each other. The end result is a higher level of technology.
What is the deadliest bullet in the world?
5.56mm hands down... slides through steel like butter... but won't slide through a body.... instead it explodes inside!!!!!
"Normal" bullets don't explode. They may expand or fragment.
5.56 may fragment if the correct bullet is used. full metal jacketed bullets are most likely to go straight through bodies. hollow point bullets tend to mushroom on impact opening a large internal cavity, but tend to stop 10 to 12 inches into the target. they make what are called frangible rounds which are a soft jacketed round with some sort of metal powder inside. these rounds disinigrate upon impact spreading the metal powder throughout the target. to name a "deadliest round", it would depend on the target, the weapon platform, and probably some other factors.
any bullet can be deadly if used correctly, but you can't go wrong with the .50 cal armor piercing incedniary round fired from a M2 BMG, "ma duece"
How does a volume gas thermometer owrk?
Gases expand or contract when heated or cooled. The main part of the thermometer has a 'large' bulb containing a gas connected by a hose to a tube filled with liquid. The expansion or contraction of the gas causes the liquid level to move this indicates the temperature.
