It turns out that Mercury and Mars have the same gravity as one another – that is, you would weigh the same on the surface of Mercury as you would on the surface of Mars, despite the fact that Mercury is smaller. Why is this the case?
Homework Answers
the formula I used is
calculated by Equating weight mg= Newton law of Gravitation
mg= GMm/R^2
g= GM /R^2
m= mass of object
M= mass of planet

1. It turns out that Mercury and Mars have the same gravity as one another – that is, you would weigh the same on the surface of Mercury as you would on the surface of Mars, despite the fact that Mercury is smaller. Why is this the case? 2. that even if Venus used to have oceans (and maybe even life), there is no way for us to tell today whether this was ever the case. Thinking about what we...

1. If another group measured the density of a cube made out of the same material as you did, should they come out with the same density? Could you have measured the volume of your cube using volume displacement? 2. 3. Could you have measured the volume of your irregularly shaped object using an equation? If a substance has a density of 1.345 g/mL, how many grams would the substance weigh if the sample 4. has a volume of 22.1...

Neutrons stars, such as the one at the center of the Crab Nebula, have about the same mass as our Sun but a much smaller diameter. 1) If you weigh 670 N on the Earth, what would be tour weigh on the surface of a newton star that has the same mass as our sun and a diameter of 23.0 km? Take the mass of the sun to be 1.99*10^30 kg the gravitational constant to be 6.67*10^-11 kg^2 , and...

Approximately what size wings would an aircraft need on Mars if its engine generates the same differences in speed as in the "Practice It" ( wing area: 3.50 m2, air flows over the top of the wing at 246 m/s, air flows underneath the wing at 223 m/s) and the total mass of the craft is 300 kg? The density of air on the surface of Mars is approximately one percent Earth's density at sea level, and the acceleration of...

One principle you will learn is that more craters on a surface indicate that the surface is older. But, the Moon and Mercury have more craters than Earth, Mars and Venus. So, are the Moon and Mercury older than the Earth, Mars and Venus? If so, how does the formation of the solar system explain that? If not, why do Mars, Venus and Earth have so few craters as compared to Mercury and the Moon?
