Mineral water, water, and salt water are all liquid solutions, while oxygen is a gas. Gases are less dense than liquids.
Answer:
0.05806
Explanation:
= Mass of asteroid x
= Mass of asteroid y
= Distance from asteroid x = 140 km
= Distance from asteroid y = 581 km
m = Mass of asteroid
Force of gravity between asteroid x and the astronaut

Force of gravity between asteroid x and the astronaut

Here these two forces are equal as they are in equilibrium

The ratio of the masses of the asteroid is 0.05806
Answer
given
Case 1-Speed of car 50 Km/h for 15 min
Case 2-Speed of car 85 Km/h for 19 min
Case 3 - Speed of car 60 km/h for 55 min
lunch break time = 25 min
a) total distance travel
we know,
distance = speed x time

D = 94.42 Km
b)
