Hydrogen is the original fuel that keeps a star "burning" by nuclear fusion.
No hydrogen and the star will die unless it can start use helium to produce energy.
The thermal energy of an object is the energy contained in the motion and vibration of its molecules. Thermal energy is measured through temperature. The energy contained in the small motions of the object's molecules can be broken up into a combination of microscopic kinetic energy and potential energy.
That's true.
Magnets attract some metals such as iron, nickel, etc.
Hope this helps~
The Moon's Effect on Ocean Tides. The gravitational pull of the Moon and the Sun makes the water in the oceans bulge, causing a continuous change between high and low tide. The oceans bulge.

Answer:
i = 5.28 A
Explanation:
The magnetic force is given by the expression
F = i l x B
the bold letters indicate vectors, let's write the modulus of that expression, where the direction between the conductor and the magnetic field is 90º, therefore the sine 90 = 1
F = i l B
i = F / l B
let's reduce the length to the SI system
l = 10 cm (1m / 100 cm) = 0.10 m
let's calculate
i = 12.9 / 0.1 3.6
i = 5.28 A
