Jupiter has about 300 times the mass of Earth and about ten times Earth's radius. What's the Estimated size of g on the surface of Jupiter?

Since gravitational forces between two masses are proportional to m1 & m2, a 300x increase in planetary mass would INCREASE the gravitational force on an object by the same factor: 300x compared to earth. Since gravitational forces are also proportional to 1/(radius squared), a 10x increase in planetary radius would DECREASE the gravitational force by a factor of 100x (10 squared), at the planet's surface. So an object on such a planet would experience gravitational forces 3x greater than those on earth.

Does DNA store its information more efficiently or less efficiently than a computer?

The data storage density is much higher in DNA than in any electronic or magnetic memory available on computers today.

For example every human cell contains 6,469.66 million basepairs (1.617415 GB) in the DNA inside its nucleus. This is similar to one RAM module on a modern computer.

What are the pros and cons of a interrupted projection?

Pros- The show the correct sizes and shapes of land masses by cutting out parts of the oceans.

Cons- Cuts on the map make it impossible to measure distance accurately or plot a course across the ocean.

How do you compare two or more items?

When comparing two items or two objects, then look for the similarities (what is the same) and differences (what is different) between them.

Where can one find a GPS comparison?

Online review sites are a great place to look for comparisons of different GPS types. Users write the reviews and give feedback, so it is easier to see the advantages and disadvantages of each one.

What were pros and cons of trebuchet?

Pros of the trebuchet include its ability to launch heavy projectiles over long distances with great accuracy and power, making it effective for siege warfare. Its mechanical design allows for a relatively simple construction using available materials. However, cons include its large size and the extensive manpower required to operate it, as well as vulnerability to counter-siege attacks. Additionally, the time it takes to reload and reposition can limit its effectiveness in fast-paced battles.

Difference between osmosis and active transport?

The difference between osmosis and active transport is that osmosis takes place only in water molecule and active transport takes place in takes place in the internal lining of the small intestine. 2 osmosis takes place in presence of concentration gradient and active transport against the concentration gradient.

What is the definition of comsumerism?

What is the definition of ophthalmorrhexis?

Comparison and contrast?

There definitions of contrast and comparison are quite different. Contrast simply means stating differences while comparison means stating similarities between two things.

Is the sun's gravity stronger than the earth?

Yes, the sun has much more mass than the earth so the sun warps spacetime much more than the earth warps spacetime. The amount that spacetime is warped by an object is proportional to the strength of that object's gravity.
