ACELLUS PHYSICS HELP! In the diagram, q1 = +6.39*10^-9 C and q2 = +3.22*10^-9 C. What is the electric potential at point P? Include a + or - sign. (Hint: The distance from q1 to P is NOT 0.150 m.) (Remember, V adds as a scalar, NOT a vector.) (Unit = V) ​

Select the correct answer from each drop-down menu. compared to its surroundings, the concentration of solutes is low inside a cell. so, the cell is with respect to its surroundings. a particular solute in this cell uses energy for its transport from the cell to its surroundings. this type of transport is called

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
