Answer:
Earth’s gravitational force is stronger
Explanation:
Earth’s gravitational force is stronger than the moon because of the presence of more massive objects in earth; on the flip side, the moon’s gravity is weaker than the earth due to smaller in size as compared to the earth. Earth gravity is denoted by g; conversely, moon gravity is denoted by gm
I believe the answer is chemical reactivity because: Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties.
Answer: D
8.403 m/s
Explanation:
Given that the women's world record for the 400-meter run around an oval track is held by Marita Koch, with a time of 47.60
seconds.
Her average velocity during this race will be
Velocity = distance/ time
Velocity = 400 / 47.6
Velocity = 8.403 m/s
Therefore, her average velocity during this race will be 8.403 m/s
D is therefore the correct answer.
