Estimated Mass of Planet (10^23 kg)

Question

Planet
W 6.4
X 3.3
Y. 59.7
Z 48.7
Assuming these planets were similar in radius, which planet would an object weight the most?
A. On planet w
B. On Planet X
C. On planet y
D. On planet Z

Answer 1

To determine which planet an object would weigh the most on, we need to compare the mass of the planets. So, the planet with the highest mass would result in the highest weight for an object.

Comparing the masses of the planets:
W has a mass of 6.4 × 10^23 kg.
X has a mass of 3.3 × 10^23 kg.
Y has a mass of 59.7 × 10^23 kg.
Z has a mass of 48.7 × 10^23 kg.

Based on the given masses, planet Y has the highest mass (59.7 × 10^23 kg), so an object would weigh the most on planet Y.

Therefore, the correct answer is C. On planet Y.

Answer 2

What is the difference between mass and weight?
A. Mass depends on location. Weight depends on the force of gravity
B. Mass depends on the force of gravity. Weight is the same
C. Mass measures the force of gravity. Weight measures matter
D. Mass is the same everywhere. Weight depends on the force of gravity

Answer 3

D. Mass is the same everywhere. Weight depends on the force of gravity.

Answer 4

When you jump, you exert A pushing force against the ground. Gravity pulls you back down. Why can a person jump higher on the moon then on the Earth?
A. A person weighs more on the moon then on earth
B. Pushing forces are stronger on the moon then on earth
C. A person has less mass on the moon then on earth
D. The gravitational force on the moon is weaker than on the Earth

Answer 5

D. The gravitational force on the moon is weaker than on the Earth

Answer 6

When you hold a textbook and a pencil, why does the textbook feel heavier than the pencil?
A. The textbook has a stronger attraction to earth
B. Your hand repels the textbook with less force
C. The textbook has less mass than the pencil
D. You can grab the pencil with more strength

Answer 7

C. The textbook has less mass than the pencil
