Star x has a magnitude of 13.star y has a magnitude of 10.the brightness is?

star y is brighter than star x

Explanation:

Actually the brightness of a star is seen in its magnitude, the lower the magnitude the brighter the star, and Also the larger the magnitude the dimmer the star

To calculate the difference in magnitude

Star x has a magnitude of 13

Star y has a magnitude of 10

The difference in magnitude is

13-10= 3

Hence star y is brighter than star x

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
