<span>In assumption that there were two scientists who used
different measurement systems in their research. The problems that might arise
if they shared their data is obviously and primarily error. Errors are
recognized and one element in every measure, system and quantity. Error was
already even present in the measurement system alone a scientist used and it
will furthermore aggregate, when these two different scales are combined the
more error escalates in the process. There are two types: random and systematic
error. </span>

Answer:
A
Explanation:
Pressure, temperature are measurable properties and they are also known as physical properties.
Answer:
21 psi
Explanation:
The weight of the car is:
W = mg
W = 1000 kg * 9.8 m/s²
W = 9800 N
Divided by 4 tires, each tire supports:
F = W/4
F = 9800 N / 4
F = 2450 N
Pressure is force divided by area, so:
P = F / A
P = (2450 N) / (0.13 m × 0.13 m)
P ≈ 145,000 Pa
101,325 Pa is the same as 14.7 psi, so:
P ≈ 145,000 Pa × (14.7 psi / 101,325 Pa)
P ≈ 21 psi
