Read the scenario. A car travels 25 m/s forward for 10 s. Which option accurately identifies the measurements within the scenari
o that are vector quantities and describes why? a.The measurements 25 m/s and 10 s are vector quantities because these numbers are both measurements that do not include direction.
b. The measurement 10 s is the only vector quantity because it measures time.
c. The measurement 25 m/s is the only vector quantity because it is a measurement of speed.
d. The measurement 25 m/s forward is the only vector quantity because it is a measurement that includes a direction.
For a vector, a quantity must have both magnitude as well as the direction. For a scalar, a quantity have only the magnitude. In this case, the car moves in forward direction. This is the only difference between the vector and the scalar.
Out of given option,s the correct option is (c) "The measurement 25 m/s is the only vector quantity because it is a measurement of speed".
The four strokes in order are the intake stroke, the compression stroke, the power stroke, and the exhaust stroke. Fuel is ignited during the power stroke.
