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.
Answer:
Ns = 293 turns
Explanation:
The magnetic field of a solenoid is given as follows:
B = μ₀NI/L
where,
B = Magnetic Field = (40.5 Gauss)(1 T/10000 Gauss) = 4.05 x 10⁻³ T
μ₀ = Permeability of Free Space = 4π x 10⁻⁷ T/Am
N = No. turns in solenoid = ?
I = Current = 0.05 A
L = Length = 10 cm = 0.1 m
Therefore,
4.05 x 10⁻³ = (4π x 10⁻⁷ )(N)(0.05)/0.1
N = (4.05 x 10⁻³)/(6.28 x 10⁻⁷)
N = 6446 turns
Now, we use turns ratio formula for transformer:
Np/Ns = Vp/Vs
where,
Np = No. of turns in primary coil = 6446 turns
Ns = No. of turns in secondary coil = ?
Vp = Primary Voltage = 220 V
Vs = Secondary Voltage = 10 V
Therefore,
6446 turns/Ns = 220 V/10 V
Ns = 64460 turns/220 V
<u>Ns = 293 turns</u>
14.0.5 cm 13. wind speed surface area temperature
Answer:
Sand!
Explanation:
Water has very high specific heat, which means that it needs to absorb quite a bit of energy before its temperature starts to change. Sand has a much lower specific heat, so it needs to absorb less energy.
Hope this helped! If so, would it be possible to get brainliest~
If not, that's fine too! Have a nice day :)
<span>Most important information when passing near a lighthouse is the water depth.
</span>Today there are many complex navigation instruments,but in the past the lighthouse were the only navigation sailors had. However, the lighthouse still is very important in the navigation. There is an information chart on every lighthouse that gives information about <span> the location of the lighthouses and the depth of the water. With these information an experienced sailor can navigate even without modern instruments.</span><span>
