The answer to this question is HBr
Answer:
A
Explanation:
In a cold front set-up, the boundary between the cold and warm air masses is relatively steep, typically causing the warm air in front of it to rise rapidly.
C. The gravity on the Moon is less than the gravity on Earth.
Explanation:
The weight of Neil Armstrong changed because the gravity on the Moon is less than the gravity on earth. We can infer that the gravity on moon is one-sixth the gravity earth.
- Mass of Armstrong on earth and moon is the same. Mass is the quantity of matter contained in a substance. Since he has the same quantity of matter on earth and moon, his mass will be the same.
Weight is a function of mass and gravity on a body.
Since his weight reduced, we can infer that the gravity on the moon is lesser:
Weight = mass x gravity.
