Answer:
27 N
Step-by-step explanation:
Since force varies directly with acceleration, we can introduce a constant, k, and write 
When force is 15, acceleration is 5, so plug it into the equation and solve for k:

Now, to find force, we use a = 9 and k = 3, so

The force is 27 N

Answer:
1680
Step-by-step explanation:
Number of distinct Toppings wanted = 4
Total number of vegetarian topping = 8
To choose 4 distinct toppings from a total of 8
Using permutation :
nPr : n! (n - r)!

8P4 = (8*7*6*5)
8P4 = 1680
