Two tugboats pull a disabled supertanker. each tug exerts a constant force of 1.60×106 n, one at an angle 13.0 west of north, and the other at an angle 13.0 east of north, as they pull the tanker a distance 0.700 km toward the north.

what is the total work done by the two tugboats on the supertanker?

express your answer in joules, to three significant figures.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Could someone me find the answer to this problem.

When using the scientist method, which step comes last?
