Examine the scenario.
a car starts from rest and uniformly accelerates to a speed of 30 mi/h in 6 s. the car moves north the entire time.
which option correctly lists a vector quantity from the scenario?
distance: 30 mi
acceleration: 5 mi/h/s north
speed: 30 mi/h
velocity: 5 mi/h/s north

  acceleration: 5 mi/h/s north

Step-by-step explanation:

Distance and speed are not vector quantities. (There is no direction associated with them.)

The units of velocity are distance/time, not distance/time², so that choice is incorrect.

The correctly described vector is that of acceleration.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

the answer to your question is b.
