Nitrogen has a melting point of -210.0°c and a boiling point of -195.8°c. a sample of nitrogen is heated from -215.0°c to -200.0°c. which of the following best describes what happens to the nitrogen atoms during this transition? a. they lose enough energy to be held in a permanent location. b. the attractive forces between them decrease, allowing the atoms to move relative to one another. c. they gain enough energy to move relative to one another. d. they gain so much energy that the attractive forces between them have no effect on their motion.

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)

Currents in dc transmission lines can be 100 a or higher. some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. for a line that has current 150 a and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? express your answer in teslas and as a percentage of the earth’s magnetic field, which is 0.50 g. is this value cause for worry?
