A proton has mass 1.7 ✕ 10^−27 kg. What is the magnitude of the impulse required to increase its speed from 0.992c to 0.995c?

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
