a.
To calculate the value of
a.

Answer to Problem 52E
Explanation of Solution
Given information:
The relation of T , g , L is given by
Calculation:
Obtain derive of T in terms of g .
b.
To explain that if g increases, will T increase or decrease, will a pendulum clock speed up or slow down.
b.

Answer to Problem 52E
If g increases then T decreases and as T decreases the pendulum will speed up.
Explanation of Solution
Given information:
The relation of T , g , L is given by
According to part (a) you have
Since the time period T is the time it takes to complete a swing. The more is the period the less is the speed. As T decreased pendulum will speed up.
c.
To find dg and estimate the value of g at the new location.
c.

Answer to Problem 52E
The value of dg is
Explanation of Solution
Given information:
A clock with 100 cm pendulum is moved from a location where
Calculation:
According to part (a) you have
Now substitute the values in the above equation
For g ,
Therefore,
The value of dg is

- The spread of an infectious disease is often modeled using the following autonomous differential equation: dI - - BI(N − I) − MI, dt where I is the number of infected people, N is the total size of the population being modeled, ẞ is a constant determining the rate of transmission, and μ is the rate at which people recover from infection. Close a) (5 points) Suppose ẞ = 0.01, N = 1000, and µ = 2. Find all equilibria. b) (5 points) For the equilbria in part a), determine whether each is stable or unstable. c) (3 points) Suppose ƒ(I) = d. Draw a phase plot of f against I. (You can use Wolfram Alpha or Desmos to plot the function, or draw the dt function by hand.) Identify the equilibria as stable or unstable in the graph. d) (2 points) Explain the biological meaning of these equilibria being stable or unstable.arrow_forwardFind the indefinite integral.
