Explain the Inverse Square Law.
Homework Answers
inverse square law is defined as that any specified physical quantity is inversely proportional to the distance square from the source of the physical quantity. for example intensity of light. mathematically it can be well understood as
intensity 1 / intensity 2 = second distance2 / first distance2
when a conserved quantity or energy is even;y distributed from the source point, then the inverse square law is applicable.
some of the examples includes - gravitational force, electromagnetic radiations, etc.

Due to the inverse square law, the image at the margin of the x-ray film will be slightly darker than that in the middle. Suppose a chest x-ray projection system has a perfect point source, and the source-detector distance is 2 meters. If we require that the intensity variation across the film (when no object is imaged) must be less than 5%, calculate the largest size of the film that we can use. Suppose a square film

According to the inverse square law of light, how will the apparent brightness of an object change if its distance to us doubles? Its apparent brightness will decrease by a factor of 4. Its apparent brightness will increase by a factor of 2. Its apparent brightness will remain the same. Its apparent brightness will decrease by a factor of 2. Its apparent brightness will increase by a factor of 4. CHOOSE ONE

3. (6 pts) Newton's law of gravity and Coulomb's law are both inverse-square laws. Consequently, there should be a "Gauss's law for gravity." The electric field was defined as E" =F" onq/q, and we used this to find the electric field of a point charge. a) Using analogous reasoning, what is the gravitational field g" of a point mass? Write your answer using the unit vector r', but be careful with signs; the gravitational force between two "like masses" is...

Predict and interpret the effects of Doppler shift. Use the inverse square law equation to relate brightness and luminosity. Use magnitudes to describe brightness and color. Relate stellar properties and the OBAFGKM classification system. Read H-R diagrams for stellar temperatures, radii, and luminosities. Predict the ages of stellar clusters based on their color-magnitude diagrams. Identify the major steps of stellar evolution by name and on the HR diagram. Relate supernovae and compact objects to the stars that produce them.
