An atom is a particle with a neutral charge
Answer:
6 significant figure
Explanation:
The digits 111328 all are 6 figures with no figure being zero, neither zero after the other digits. In this case, all the numbers are significant and since they are only six numbers, then this is a six significant figure. In case we add another zero after digit 8, the zero is not significant but if added either infront of 8 or 2, the zero becomes significant.
The ant's resultant velocity is 0.51 m/s at 78.7°
Since the ant is moving with a velocity of 0.1 m/s in the +x direction relative to the treadmill, and the treadmill is moving 0.5 m/s in the +y direction, the magnitude of the resultant velocity of the ant relative to the ground (since both directions are perpendicular) is thus
V = √(x² + y²)
= √[(0.1 m/s)² + (0.5 m/s)²]
= √[0.01 m²/s² + 0.25 m²/s²]
= √(0.26 m²/s²)
= 0.51 m/s.
The direction is Ф = tan⁻¹(y/x)
= tan⁻¹(0.5 m/s ÷ 0.1 m/s)
= tan⁻¹(5)
= 78.69°
≅ 78.7°

Explanation:
A molten steel is in a liquid phase of matter. It has no defined volume of shape at this state. The particles inside this materials in this form is randomized by they are still attached to each other.
- On cooling, when the molten steel solidifies and sets into a solid steel beam, the particles take up a fixed position and forms a definite shape and this confers a definite volume on them.
- The randomized particles stops and forms fixed crystals about their lattice.
- This way, the beam can carry and support a fixed amount of load.
