Question
Chapter 22, Problem 1QP
To determine
The correct statement
Expert Solution & Answer
Answer to Problem 1QP
Option (d)
Explanation of Solution
According to
The critical density is proportional to the square of the Hubble constant, which is used in measuring the expansion rate of the universe.
Comparing the critical density to the actual density can help scientists to understand the cosmos.
Conclusion:
The density of the universe dictates whether it will be open, closed, or flat. Therefore, option (d) is correct.
The density of the universe dictates whether it will be open, closed, or flat. Therefore, option (a) is incorrect.
The density of the universe dictates whether it will be open, closed, or flat. Therefore, option (b) is incorrect.
The density of the universe dictates whether it will be open, closed, or flat. Therefore, option (c) is incorrect.

The force of the quadriceps (Fq) and force of the patellar tendon (Fp) is identical (i.e., 1000 N each). In the figure below angle in blue is Θ and the in green is half Θ (i.e., Θ/2). A) Calculate the patellar reaction force (i.e., R resultant vector is the sum of the horizontal component of the quadriceps and patellar tendon force) at the following joint angles: you need to provide a diagram showing the vector and its components for each part. a1) Θ = 160 degrees, a2) Θ = 90 degrees. NOTE: USE ONLY TRIGNOMETRIC FUNCTIONS (SIN/TAN/COS, NO LAW OF COSINES, NO COMPLICATED ALGEBRAIC EQUATIONS OR ANYTHING ELSE, ETC. Question A has 2 parts!
