Saeed is playing with his drone. The drone's velocity relative to the wind is plotted as the blue arrow.
The wind's velocity relative to Saeed is plotted as the purple arrow.
Use the graph to calculate the orientation of the drone's velocity to Saeed represented by the red
arrow, and measured anticlockwise from the positive x-axis (east).

Well the magnitude of its acceleration related to that car starts with the oil change like when you have to change the oil in your car you have to make sure that your precious car is starting really propley and very well

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.

Answer(b) both involve the use of levers;
