Examine the scenario. a sports car starts from rest and uniformly accelerates to a speed of 60 km/h in 6 s. the car moves east the entire time. which option represents a vector quantity present in the scenario? acceleration: 10 km/h/s east speed: 60 km/h velocity: 10 km/h/s east distance: 60 km

Answer;

-Acceleration: 10 km/h/s east

Explanation;

-The quantity is either a vector or a scalar. Scalars are quantities that are fully described by a magnitude (or numerical value) alone while Vectors are quantities that are fully described by both a magnitude and a direction.

Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.

In this case , a =( v-u)/t ; where a is the acceleration, v is the final velocity, u is the initial velocity and t is time.

      a = (60 - 0)/6

         = 10 km/h/s

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
