The magnetic field on the sun is created by <u>flowing charged plasma</u> a liquid iron core flowing charged plasma friction iron in the solar wind.
Plasma, a gas-like state of matter in which electrons and ions have separated to produce a very hot mixture of charged particles, makes up the sun. Magnetic fields are naturally produced as charged particles move, and these fields have an additional impact on the motion of the particles.
Because the magnetic fields above the surface of the sun direct the travel of that plasma and cause the loops and towers of material in the corona to shine brilliantly in EUV photos, we can see the shape of the magnetic fields there.

Answer:
Explanation:
2 )
power of an electric device = V² / R where V is volts and R is resistance
putting given data
power = 9²/ 5
= 16.2 J/s
energy produced in 7 minutes
= 16.2 x 7 x 60
= 6804J .
3 ) Power of an electrical device
= V² / R
= V X I where I is current
= 4.5 x .5
= 2.25 W or J/s
4 )
energy used in 3 minutes with power of 2.25 W
= 2.25 x 3 x 60
= 405 J .
7 )
power of a electrical device
= V x I
IR x I where R is resistance .
= I²R
putting given data
power = .005² x 50
= 1.25 x 10⁻³ W .
8 )
Energy used up by a 60 W bulb in 2.5 hours
= 60 x 2.5 x 60 x 60
= 5.4 x 10⁵ J .
Answer:
Approximate escape speed = 45.3 km/s
Explanation:
Escape speed
Here we have
Gravitational constant = G = 6.67 × 10⁻¹¹ m³ kg⁻¹ s⁻²
R = 1 AU = 1.496 × 10¹¹ m
M = 2.3 × 10³⁰ kg
Substituting
Approximate escape speed = 45.3 km/s
