What is the ans for que.6​

Answer 1

Explanation:

1 question.

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

2 question.

Volume of brick:

In millimetre (mm) units = (215 mm × 102.5 mm × 65 mm) = 1 432 438 mm3

.

In metre (m) units = (0.215 m × 0.1025 m × 0.065 m) = 0.0014 m3

.

Density = mass/volume, so mass = density × volume.

Mass = 1800 kg/m3

× 0.0014 m3

= 2.52 kg

Weight of brick = 2.52 kg × 10 = 25.2 N = 0.025 kN.
