Answer:
a,c,g,H, are scalar
Explanation:
- scalar means the quantity has only magnitude but no specific direction
- vector means having both magnitude and direction
- by this we can calculate whether the given example is vector or scalar
- force is a vector quantity because it has the direction of velocity by Newton's second law
- pressure may have direction because it flows from low to high
- I think density don't have direction but if you think clearly less dense particles flow on high dense particles this implies density has direction
