Answer:
The answer is "Keep at least a couple of extra digits beyond those needed for determining significant figures."
Explanation:
Answer: Speed = 4m/s
Strength = 7.1T
Explanation: P= 4.0w
N = 1.0
V= ?
Power = force x velocity
Velocity = power/ force
V= 4.0w/1.0N
V = 4m/s
Strength of the magnetic field
B = √PR / lv
Where; l = length 10cm
R= 2.0
P= 4.0w
V= 4m/s
B = √ (4.0w) × (2.0) / (10cm) × (4m/s)
B = 7.1T
Answer:
The international bureau of weights and measures is an international organization to bring about the unification of different measurement systems to make or establish international standards and prototypes, etc.

The light reactions could be viewed as analogous to a hydroelectric dam. In that case, the wall of the dam that holds back the water would be analogous to the thylakoid membrane.
Thylakoid membrane is present in cyanobacteria and chloroplasts of plants. It plays a crucial role in photosynthesis and photosystem II reactions.
In general, these are the regions where light-dependent reactions take place. The thylakoid membrane is a lipid-bound membrane that maintains potential difference and also controls the flow of liquids across the membrane during light reactions.
In the provided case, we can see that the wall of the dam holds back the water, similarly, in light-dependent reactions, thylakoid membranes control the liquid flow and also regulate the potential gradient across the membrane and also allow the selective proteins to pass through.
