Is a hard material easily scratched?
A hard material is not easily scratched, as its strong structure makes it resistant to scratches. Examples of hard materials include diamond and sapphire, which are known for their durability and scratch resistance.
What material is strong hard flexible and sinks in water?
Steel is a material that is strong, hard, and flexible. It also has a high density, so it sinks in water.
Can a magnet erase information from memory sticks and computers?
A magnet can only change information that is stored magnetically and if the magnet's magnetic field is strong enough. Memory sticks do not store information magnetically, they use Flash memory which stores information electrostatically. So no, a magnet can not erase information on a memory stick. Computers usually use hard disks which do store information magnetically, so in principle a magnet could erase information from a hard disk. However the magnet would have to be very strong (much stronger than is likely to be available at home) and held very close to the hard disk (probably be inside the computer case or even inside the hard disk case itself) to be able to to erase the information. Computers before the 1970s usually used magnetic core memory instead of DRAM as their main memory. While this stored information magnetically, the construction of the cores as rings made it impossible for any magnet to change the information: the 1 and 0 were opposite directions of magnetization around the ring shaped cores, while an external magnetic field is "linear" not "circular" and thus can't change the state of a core.
Which is the best material for insulating wires in a circuit hard rubber lead silver or tungsten?
Hard rubber
What is a hard protein material found in skin and connective tissue?
keratin
What do hard disc do?
It stores data magnetically in a manner that the computer can access relatively fast.
What does a Hard Disc do?
It stores data magnetically in a manner that the computer can access relatively fast.
What do hard discs do?
It stores data magnetically in a manner that the computer can access relatively fast.
What does it mean by steel is magnetically hard?
A magnetically hard substance is one which can be permanently magnetised using a strong magnetic force. Steel is one such substance. (A magnetically soft substance can only be magnetised temporarily.)
What is a hard magnet?
Hard magnets are permanent magnets that do not require electricity to retain their magnetism and are not easily demagnetized. They are magnetically charged naturally and can be artificially, too.
Why would hard hat be needed when climbing a tower crane?
Hard hat help the worker not to get hurt by crane or any piece of iron
What is a helicopter crane used for?
For lifting heavy objects that would be awkward or hard for a regular crane to do.
What is a is a fixed storage device that consists of one or more rigid metal platters coated with a metal oxide material?
A hard disk drive (HDD) is a fixed storage device that consists of one or more rigid metal platters coated with a metal oxide material. These platters store digital data magnetically and are read/write heads access data on the platters.
What memory has an magnetic hard drive to improve system performance?
If you are referring to RAM, none because it would slow it down. Hard drives and floppies are magnetically written to.
Why are electromagnetic waves associated with radiation?
Electromagnetic waves are associated with radiation because they can transfer energy through a vacuum or a medium without the need for a material medium. When electromagnetic waves interact with matter, they can cause the release of energy in the form of radiation such as light, heat, or radio waves.
What are hard drive platters made of and how do they contribute to the functionality of a hard drive?
Hard drive platters are typically made of glass or aluminum coated with a magnetic material. These platters store data by using a read/write head to magnetically encode and retrieve information. The platters' smooth surface and precise spinning motion are crucial for the read/write head to accurately access and store data, making them essential for the functionality of a hard drive.
What is the hard disk?
A hard disk is the physical medium information storage device of most computerized systems. It is an actual disk that rotates at high speed. The surface is coated with magnetic material, and data is stored magnetically on the surface. A tiny read/write head on the end of an arm that can move over the surface of the disk does the reading and writing to transfer the information to and from the medium.
