1. Write a general mathematical expression for an inverse square law. 2. What are other examples...
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...
S 5 Write what express the Second law of thermodynamics. Write the mathematical formulation and describe all used variables with their units.
Q) Write a mathematical expression for the overall heat transfer rate of a cross flow exchanger in general. Which part of the expression constitutes the driving force of heat transfer. Is there any term that is different from a double pipe heat exchanger. Please write clearly thank you
please help with ALL Spectrophotometry and Beer's Law Spenglerenga Prelald MT RE 1. Write the mathematical expression for Beer's law and explain each symbol in the expression 2. Use Figure 7.2 to estimate the approximate wavelength of maximum absorption for an aque- ous solution of each of the following: a. Hemoglobin (the molecule that gives blood its color) b. Chlorophyll (the pigment that gives algae their color) 3. Fill in the following for the correspondence between % transmittance and absorbance:...
Problem 22.52-Copy Part A ReviewI Constants Periodic Table Using the inverse square law for light from Mathematical Insight 15.1 in the textbook, determine the apparent brightness of the Sun in our sky. Express your answer to two significant figures and include the appropriate units. According to Olbers' paradox, the entire sky would be as bright as the surface of a typical star if the universe were infinite in space, unchanging in time, and the same everywhere. However, conditions would not...
What is the first step to be performed in the following mathematical expression? (EX) Select one: O a. Square the sum of the scores. O b. Add the squared scores. 0 C. Add the scores. O d. Square each score.
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
The inverse of a square matrix A is denoted A-1 , such that A × A-1 = I, where I is the identity matrix with all 1s on the diagonal and 0 on all other cells. The inverse of a 2×2 matrix A can be obtained using the following formula: = c d a b A − − − = − c a d b ad bc A 1...
