battery
Explanation:
Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire. The electric field in the wire coil creates a magnetic field around the nail. In some cases, the nail will remain magnetised even when removed from within the wire coil
Answer:
d. a large region outside Jupiter occupied by its magnetic field and filled with high-energy charged particles.
Explanation:
A magnetic field is generated by the movement of a charged particle in the space around it. For the case of Jupiter its magnetic field is created by the liquid metallic hydrogen in its core.
So the magnetosphere is just the magnetic field around a planet, which interacts with high-energy charged particles (for example: Cosmic Rays).
Magnetospheres protect planets from the extreme radiation coming from stars or another interstellar source.
The answer is 54.675 J
<span>The kinetic energy (Ke) of an object is the product of half of its mass (m) and the square of its velocity (v²):
</span>Ke = 1/2 m * v²
We have:
Ke = ?
m = 15 kg
v = 2.7 m/s
_____
Ke = 1/2 * 15 kg * (2.7 m/s)² = 1/2 * 15 kg * 7.29 m²/s² = 54.675 kg * m²/s²
Ke = 54.675 J
Answer:
To convert a milligram measurement to a kilogram measurement, divide the weight by the conversion ratio. The weight in kilograms is equal to the milligrams divided by 1,000,000.
