I think that it is apparent magnitude
Answer: False but read why
Heated water molecules expands ( become less dense) but they do float to the top.
Answer:
A= 61.35
B= -44.40
Explanation:
1. Using the components method we have:

Considering that the vector sum
, then:

Then:

It means the value of x and y component is 0.
2. Determinate the equations that describe each component:

Form Eq. (1):

Replacing A in Eq. (2):

Replacing values of C, α and β in (4):

Replacing value of B in (3)

It would be 2000N ( newtons )
