B is the answer - buoyant force
Answer:
ΔR = 5 s
Explanation:
The absolute uncertainty or error in an expression is
ΔR = | 
| ΔB + | 
| ΔA
the absolute value guarantees to take the unfavorable case, that is, the maximum error.
We look for the derivatives
= 1
= -1
we substitute
ΔR = 1 ΔB + 1 ΔA
of the data
ΔB = 3 s
ΔA = 2 s
ΔR = 3 + 2
ΔR = 5 s

Energy keeps our school running properly. Without energy computers, smart-boards, printers, and our lights would not work.
The world runs on energy.
The net force is zero due to the direction.
We need to know about force resultant to solve this problem. The force resultant is the total net force applied to the object according to the direction. It can be written as
R = F1 + F2 + ... + Fn
where R is force resultant (net force)
From the question above, we know that
F1 = F2 = F N
Because the direction is the same, the force will be minus each other.
R = F1 - F2
R = F - F
R = 0 N
Hence, the net force is 0 N
