Yes , the response of the light bulb depend on how fast you move the bar magnet
Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface
Lenz's law states that the induced electromotive force with different polarities induces a current whose magnetic field opposes the change in magnetic flux through the loop in order to ensure that the original flux is maintained through the loop when current flows in it.
Yes, waving a magnet around does create an electromagnetic wave which does affect the light bulb .
Due to motion of the bar, there will be a constant change in flux and due to Lenz's Law a current within the coil will be induced . This induced current can be used to power the light bulb.
As we know that the greater the speed, the greater the magnitude of the current, and the current is zero when there is no motion.
There will be change in brightness as the bar moves with faster speed.

Answer:
Speed of the satellite V = 6.991 × 10³ m/s
Explanation:
Given:
Force F = 3,000N
Mass of satellite m = 500 kg
Mass of earth M = 5.97 × 10²⁴
Gravitational force G = 6.67 × 10⁻¹¹
Find:
Speed of the satellite.
Computation:
Radius r = √[GMm / F]
Radius r = √[(6.67 × 10⁻¹¹ )(5.97 × 10²⁴)(500) / (3,000)
Radius r = 8.146 × 10⁶ m
Speed of the satellite V = √rF / m
Speed of the satellite V = √(8.146 × 10⁶)(3,000) / 500
Speed of the satellite V = 6.991 × 10³ m/s
A liquid is a matter that neither has a fixed shape but fixed volume...in college really need to know this.
GOOD LUCK
<span>An example of a high energy electromagnetic wave is "X-Ray"
When car runs, it's chemical energy (gasoline) converts into mechanical energy
Temperature is the measure of hotness or coldness of the body, so when heat expose to a substance, it's degree of hotness increases & it's temperature increases
Hope this helps!
