You learned that different types of forces act on objects directly and indirectly you also learn what happens when forces are balanced and unbalanced examine the diagram below showing forces acting on a box. 1. Explain how you calculate the net force in any direction on the box.
2. Suppose an upward force of 15 N is added to the box what will be the net vertical force on the box.
3. What force could be applied to the box to make the net force in the horizontal direction zero? explain.
4. Suppose a force of 25 N to the right is added to the box. what will be the net force to the right?

is there any options? maybe im just not seeing them but i need the options to

explanation:

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
