Answer:

4 m

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 10 m/s

Acceleration (a) = –8m/s²

Time (t) = 2 s

Displacement (s) =?

The displacement of the object can be obtained as follow:

s = ut + ½at²

s = (10 × 2) + (½ × –8 × 2²)

s = 20 + (–4 × 4)

s = 20 + (–16)

s = 20 – 16

s = 4 m

Thus, the displacement of the object is 4 m.

TUL<br> Which of the following terms refers to the exactness of a measurement?
Oksana_A [137]

Accuracy

Explanation:

Accuracy is a term that refers to the exactness of a measurement.

Accuracy is the nearness of measured value to the true value.

The difference between the measured value and the true value is the uncertainty in the measurement.

  • The closer a measured value is to the true value, the more accurate the measurement is. The lesser the error accrued in the process.
