Answer:
yes for sure
Explanation:
iran oy has 3000 ballistic missiles but america has thousands of nukes. we can easily outnumber their forces as well. this will be a easy victory for us but will result in massive casualties on both sides
Answer:
A = true.
Explanation:
The statement made in the Question or problem above is TRUE/correct. The term known as " catch basin" is an important and essential part of the drainage system that is should be built in a community(whether housing community, industrial community or commercial community).
The catch basin is very important because it helps in making sure that they act as sieve to get all the dirt such as leaves from water running on the surface(runoffs).
Question:
The following tabulated data were gathered from a series of Charpy impact tests on a commercial low-carbon steel alloy.
Temperature(∘C)50403020100-10-20-30-40Impact energy (J)76767158382314951.5
(a) Plot the data as impact energy versus temperature.
(b) Determine a ductile-to-brittle transition temperature as the temperature corresponding to the average of the maximum and minimum impact energies.
(c) Determine a ductile-to-brittle transition temperature as the temperature at which the impact energy is 20 J.
Answer:
a) see the attached graph
b) max E = 76 and Min E =1.53 average = 77.5/2 = 38.75 J
this corresponds to about 10° C
c ) at E = 20 J temperature is about -2°C
Answer:
Explanation:
In this case acceleration is defined as:
,
where k is a constant to be found.
To find the expressions for velocity and position as a function of time you must integrate the expression above for acceleration two times.
Initial conditions and boundary conditions are defined with the rest of the data as:
First integration is equal to:
The boundary condition and initial condition can be used to calculate and :
With this expression for velocity is defined as:
The same can be done to get to expression for position:
To get the total distance traveled you can integrate the velocity expression from time=0 sec to time=4 sec:
