What is the difference between accurate data and reproducible data?

Physics
2 answers:
Shtirlitz [24]3 years ago

Answer:


Accuracy is ‘the state of being correct’ and on the other hand precision is ‘the state of being exact.


Explanation:


Accuracy shows the nearness of the measurement with the actual measurement while precision shows the nearness of an individual measurement with other measurements.


Accuracy focuses on the errors caused by the problem in the instrument. while precision is concerned with errors, which occurs periodically with no recognizable pattern.


If the measurement is precise but inaccurate, the result will not be the expected one. And if the result is accurate but imprecise, then there are huge variations in the measurements. And finally, if the actual measurement is neither accurate nor precise, then the result would not have correctness and exactness at the same time.

Accuracy is a general concept while precision is more of a mathematical concept.

An assistant for a football team carries a 26.0 kg cooler of water from the top row of the stadium, which is a distance h = 17.5
frozen [14]

The weight of the cooler is (mg). That's (26)(9.8) = 254.8 Newtons.

Its gravitational potential energy while it's up in the top row is (mgh). That's (254.8)(17.5) = 4,459 Joules.

That's how much work it took to get the cooler up to the top row, and that's the energy it gives up when it moves back down to the bench.

In order to bring it down . . .

-- Gravity does 4,459 joules of work on the cooler.

-- The team assistant does NEGATIVE 4,459 joules of work on it.

The uniform crate has a mass of 150 kg. The coefficient of static friction between the crate and the floor is μs = 0.2. The coef
Tatiana [17]

Answer:

The man will be able to move the crate.

Explanation:

\mu_s = Coefficient of static friction between the crate and the floor = 0.2

\mu'_s = Coefficient of static friction between the man's shoes and the floor = 0.4

m_c = Mass of crate = 150 kg

m_p = Mass of man = 85 kg

g = Acceleration due to gravity = 9.81 m/s²

Horizontal force in order to move the crate is given by

F_h=\mu_sm_cg\\\Rightarrow F_h=0.2\times 150\times 9.81\\\Rightarrow F_h=294.3\ N

Maximum force that the man can apply

F_m=\mu'_sm_pg\\\Rightarrow F_m=0.4\times 85\times 9.81\\\Rightarrow F_m=333.54\ N

Here it can be seen that F_m>F_h.

So, the man will be able to move the crate.
