16. Which of the following describes an iron ore?(Points : 3) an ironcarbon alloy a pure metal an ionic compound of iron a rock containing a lot of iron
the problem isn’t too stressful. would nicely be simplified. On a slump, verify this: 6.3^2 + 12^2 13.6^2. Yahoo! Left hand area balances suited hand area! The triangle with sides 6.3 cm, 12 cm and 13.6 cm is sweet-angled. Makes issues easier. Draw a triangle XYZ with XY 6.3 cm, YZ 12 cm and XZ 13.6 cm (the hypotenuse) --- on a sheet of paper. word that XY and YZ has a suited attitude between them. Circle X and Y. it is the place there are 2 currents of length 15.0 A entering the website many times. The magnetic container located at factor located at a distance R removed from an prolonged at once contemporary I is given by ability of B (mu-nought)*(I) / (2*pi*R) “mu-nought” is (4*pi*10^-7), so B (2I)/R the two currents make magnetic fields B1 and B2 at Z, so as that they are at suited angles with XZ and YZ respectively. the attitude between B1 and B2 is theta, the place theta is likewise the attitude at Z in triangle XYZ. Theta is actual got here upon via fact all 3 sides of XYZ are time-honored, employing basic sin, tan or cos. Draw a parallelogram with 2 arrows for sides, of length B1 and B2, with the attitude theta between them. locate the diagonal of the parallelogram between B1 and B2, and the attitude it makes with B1. subsequently you know it is the size and direction of the consequent container. ok, right this is the place physics ends, something is arithmetic. It’s as much as you presently to the two draw to scale or calculate.
i think a pure metal if it is an iron ore. it connot be a ionic compound, because it is an ore.
a rock containing a lot of iron
