The answer is A, because it’s the first one
Answer:
9000 kg/m³
Explanation:
Density is mass per volume.
D = M / V
D = (9.00 kg) / (0.100 m × 0.100 m × 0.100 m)
D = 9000 kg/m³
Answer:
the answer is
Explanation:For equilibrium
Weight = Tension
mg=T
∴T=4×3.1π=12.4πN (as can be inferred from the question)

It doesn't the sun stays still we move around the sun
In 2.34 hours, the bus travels 16.34 km.
Average speed = (distance covered) / (time to cover the distance).
Average speed = (16.34 km) / (2.34 hours) = 6.983 km/hr
