A student constructs a small sailboat a wind machine is able to blow air at a constant applied force of 5,10,15,20 newton. The student places the boat in a large tank filled with water and tests each wind force setting on the machine. Which wind force will result in the boat having the greatest speed?

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

i don't understand. explain it clearly

your answer is, orbit around the nucleus
