How does the size of a bar magnet's magnetic field compare to that of Earth's? A. A bar magnet's magnetic field is larger than Earth's. B. A bar magnet's magnetic field is smaller than Earth's. C. A bar magnet's magnetic field is the same size as Earth's.

A. A bar magnet’s magnetic field is larger than Earth’s.

Step-by-step explanation:

The average magnetic field strength in the Earth's outer core was measured to be 25 Gauss, 50 times stronger than the magnetic field at the surface.

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
