(b) a ship is sailing in dense fog and it could
be close to dangerous cliffs. the captain
switches on the fog horn. the horn sounds
and the echo is heard 4s later. the speed
of sound in air is 340 m/s.
(i) calculate the distance between the
ship and the cliff.

Arise 8 run 1 this means go 8 up and 1 across, which is steepest

Ibelieve that the correct answer is: c. along plate boundaries

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.

F  you double the  force, you double the acceleration, but  if  you double the  mass, you velocity. all bodies accelerate at the  same  rate regardless of size or  mass.
