A 5-newton force directed east and a 5-newton force directed north act concurrently on a point. Calculate the resultant of the two forces.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
