The motor of a four wheeler traveling along a muddy trail generates an average power of 7.05 104 w when moving at a constant speed of 15 m/s. when pulling a log along the trail at the same speed, the engine must generate an average power of 8.15 104 w. what is the tension in the tow rope pulling the log?

Which is the correct symbol for an isotope of iodine with 53 protons and 78 neutrons?

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.)

It is really hard for me right know
