Answer: precise
Explanation:
Three different people weight a standard mass of 2.00 g on the same balance. Each person obtains a reading of 2.32 g for the mass of the standard. These results imply that the balance that was used is precise.
Precision can be defined as the closeness of measured values to each other, for a measuring equipment it is the closeness of the values of readings obtained at different times to each other. It does not necessarily means the measurements are accurate(closeness to the actual value). Therefore, in the case above where three different people measured the same mass on the same balance, and each of them obtained the same value which is different from the standard value. We can say the balance used is precise because the three readings are the same.
No it will not because F will equal 3 not 0
This is possible due to inertia of motion. which is nothing but newton's first law.
according to this law , an object tries to retain its state of motion or rest unless acted upon by an external force.
consider an object placed on a paper, initially both the object and paper are at rest. to pull the paper , we apply force on the paper and paper gains velocity. but the object keeps its motion of rest and hence the paper can be removed without moving the object.
Answer:
Explanation:
The weekly water consumption of Kimonoski is:
The total energy required per week for hot water is:
Given that,
Time period of simple pendulum is 1.55 s.
Time period of simple pendulum for A student =1.25 s
Time period of simple pendulum for B student =1.5 s
We know that
The accuracy is defined as how close a measurement is to a known value .
The result of student of A is 1.25 s. It is more precise because it has more significant figure than student B's result of 1.6 s.
But the measurement made by student B's is much closer the known value of 1.55 s.
Hence, The most probable source of error is the result of student A.
