question 95

Multiple Choice

In the late 1800s,Kelvin and Helmholtz suggested that the Sun stayed hot due to gravitational contraction.What was the major drawback to this idea?

• A)It predicted that the Sun would shrink noticeably as we watched it,but the Sun appears to be stable in size.
• B)It is physically impossible to generate heat simply by making a star shrink in size.
• C)It predicted that the Sun could shine for about 25 million years,but geologists had already found that Earth is much older than this.
• D)It predicted that Earth would also shrink in size with time,which would make it impossible to have stable geology on our planet.

Definitions:

Random Numbers

Random numbers are sequences of digits (usually between 0 and 1) generated in such a way that each number has an equal probability of occurring, commonly used in simulations and statistical sampling.

Cumulative Probability Distribution

A statistical function that describes the probability of a random variable falling within a certain range or being less than a specific value.

Monte Carlo Simulation

A computational technique that uses random sampling to obtain numerical results, often used for risk assessment or to solve physical and mathematical problems.

Cumulative Probability Distribution

A function that gives the probability that a random variable is less than or equal to a certain value.
