The planets from strongest magnetic field to weakest magnetic field is Jupiter > Earth > Venus.
Magnetic fields are generated by the movement of magnetic material located in side the planet, usually at the core.
Jupiter, the biggest planet in our planetary system, likewise has the biggest magnetic field, producing a magnetosphere bigger than the Sun. It`s magnetic field is created by its fast rotation of 9.8 Earth hours. Dissimilar to Earth, Jupiter`s magnetic field is not produced by its core yet by interaction in its external core, which comprises of liquid metallic hydrogen.
Earth's magnetic field is produced by liquid metal at the center and Earth's fast pivot of 24 hours creates enough movement of the liquid to animate a magnetic field. While Venus does not have a magnetic field, likely on account of it's slow rate at around 243 Earth days, it's as yet shielded from sun oriented breezes utilizing an alternate kind of magnetism.
Therefore, the Jupiter have magnetic fields much stronger than that of the Earth and Venus.
The speed of the car is 60 m/s
Explanation:
The speed of an object is a scalar quantity telling "how fast" the object is moving, regardless of its direction. It can be calculated as follows:

where
d is the distance covered
t is the time taken
For the car in this problem, we have
is the distance covered
is the time taken
Subsituting into the equation, we find the speed:

I think this is about the 5th or 6th time I've seen this question
submitted to Brainly. So far, nobody has yet given us any of
the rest of the question ... the part that tells us something about
the vectors, so that we have some way to know their magnitudes.
So far, nada.
