Answer:
0.56 km/s
Explanation:
We will define a single system of units for measurement, for this case meters per second [m/s]. That is, we must convert the rest of units such as centimeters per second and kilometers per second to meters per second.
![560[\frac{cm}{s}]*(\frac{1m}{100cm} )=5.6[m/s]\\0.56[\frac{km}{s}]*(\frac{1000m}{1km} )=560[m/s]](https://tex.z-dn.net/?f=560%5B%5Cfrac%7Bcm%7D%7Bs%7D%5D%2A%28%5Cfrac%7B1m%7D%7B100cm%7D%20%29%3D5.6%5Bm%2Fs%5D%5C%5C0.56%5B%5Cfrac%7Bkm%7D%7Bs%7D%5D%2A%28%5Cfrac%7B1000m%7D%7B1km%7D%20%29%3D560%5Bm%2Fs%5D)
Therefore the speed of 0.56 [km/s] is the greatest of all
Answer:
the answer is at least 3 feet
Explanation:
In order to ensure that a cable is not affected by electromagnetic interference, it should be at least 3 feet away from fluorescent lighting.
This is because, cables can be adversely affected by electromagnetic interference - which is a disturbance that affects an electrical circuit due to either electromagnetic induction or radiation emitted from an external source - and insulation alone cannot provide adequate protection for these cables.
Therefore, the cables should be kept a few feet away from flourescent lighting in order to prevent this interference.
Answer:
Waves are disturbance of the space (or of a medium) that consist of periodic oscillations that carry energy without carrying matter.
Waves can be of two types:
- Mechanical waves: they are transmitted through the oscillations of the particles in a medium
- Electromagnetic waves: they are oscillations of the electric and magnetic fields. These are the only waves that can travel in a vacuum
Waves consist of periodic vibrations of the particles in a medium that can oscillate in two directions:
- Back and forth along the direction of motion of the wave --> these waves are called longitudinal waves
- Up and down, so perpendicular to the direction of motion of the wave --> these waves are called transverse waves
Waves always propagate from a precise point in space, called source of the wave. So, waves are generated by this source, that somehow does work on the particles of the surrounding medium, and therefore producing the oscillation that then is transmitted through all the space around the source.

Explanation:
The pull strength is the highest possible holding power of a magnet, measured in kilograms. It is the force required to prise a magnet away from a flat steel surface when the magnet and metal have full and direct surface-to-surface contact.
