Can someone help me solve the problem?

If you run, does time pass faster than if you stand still?
Byiobgla
I once heard that time would pass faster if you moved at the speed of light. So does that mean that when someone runs, time passes faster for them, but it's not much faster, just a very small amount, so they don't notice it?
Is this calculation of the image distance correct?
1/g+1/b=1/f 1/b=1/f-1/g b= 1/ (1/f-1/g)=1(1/20-1/30)=59.99 Calculation of image size: A=b/g=59.99/30=1.999 Greetings 😬
Phew, even more confused😏?
Suppose you're moving at 95% of the speed of light. If 3 seconds have passed for a stationary observer, how many seconds have passed for the moving observer? (c = 3 10^8 m/s) Solution: T' = 0.94 s
Direction of the Lorentz force?
https://www.walter-fendt.de/html5/phde/generator_de.htm Why is the direction of movement (black) parallel to the direction of the magnetic field? According to the three-finger rule for the right hand, my index finger points down and my thumb into the plane of the drawing at the right half of the conductor loop (technical current direction). Then the middle finger points…
If the rotation of the earth core would come to a standstill, this could have an effect on the magnetic field of the earth. The magnetic field of the earth is generated mainly by the rotation of the liquid iron-nickel core. Without this rotation, the magnetic field would become weaker and eventually disappear. This could have an impact on the navigation of animals and humans, as well as on the communication and power systems based on the magnetic field.
It can also have effects on the geological processes that influence the magnetic field, such as plate tectonics, which can lead to changes in the climate and in the marine flows.
However, it is unlikely that this will happen in the near future, as the rotation of the earth’s core is very stable and changes only slowly.
I’ll go with the other one, but the two? Sorry, but I don’t see any sense in it. Although an electric motor, a transformer and a generator also functions with an electromagnetic field, they have their own electromagnetic fields and are therefore not dependent on the earth’s magnetic field in their functional base.
The Earth’s magnetic field for the biosphere on Earth is already essential, because it retains both a part of cosmic and solar radiation, and that it protects the Earth’s atmosphere from the solar wind to a sufficient extent. Without the Earth’s magnetic field, Earth would become a desert like Mars.
Your second paragraph also applies to the communication and power supply systems. Sun winds can cause electromagnetic induction and thereby impair current systems. Communication systems based on satellites could also be affected, as the radiation of the solar winds can bring the signals together.
but that doesn’t matter because it happens regularly.
No.
It is only claimed that the inner core of the earth would turn as fast as the rest of the planet, otherwise the core of the earth would normally have turned faster than the rest of the planet.

Probably. The direction of rotation changes every few decades.
So this is not an extraordinary event and should not be overrated.
This means the earth will explode in about 1 year.
No. The Earth’s core is still moving. Only relative to the rest of the earth at the “same” speed. How people come to a standstill is a mystery to me.
