Answer
To find the difference in mass, we subtract the mass of Mercury from the mass of Venus:
Mass of Venus: 4.869×1024 kg
Mass of Mercury: 3.302×1023 kg
Calculating the difference:
4.869×1024−3.302×1023=4.5398×1024 kg

Answer
To determine if Nishat is correct, we need to compare the distances from Earth to Venus and Neptune:
Distance to Venus: 4.14×1010 km
Distance to Neptune: 4.35×1010 km
Now, calculate the ratio:
(4.14×1010)(4.35×1010)≈1.051 (approximately 1.05 times)
