The wind exerts a force of 425 N to the north on a sailboat, while the water exerts a drag force of 325N in the opposite direction. What is the acceleration of the sailboat if the mass is 4100 kg?

The answer is  a.first and third quarters 

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
