<span>So we want to know is it true or false that the Sun is the ultimate source of energy on Earth. The answer is true because fossil fuels are solar energy trapped in the Earth's surface. Water cycle is dependent on solar radiation and we use water to produce electricity. We use solar panels to produce electrical energy. And also, all plant life harvests solar energy. </span>
The hotter star will be 16 times more luminous - luminosity depends on two things - the size of the star and the temperature of the star. The hotter a star is, the more energy it will give out. This will give rise to greater luminosity.
The magnetic moment may be considered, therefore, to be a vector. The direction of the magnetic moment points from the south to north pole of the magnet (inside the magnet). The magnetic field of a magnetic dipole is proportional to its magnetic dipole moment.
This i believe is true , brainlest ?
