An aircraft jet engine has a thrust of I80N. What impulse is produced in 30 S?
1 answer:
The impulse that was produced by this aircraft jet engine is 5,400 Ns.
<u>Given the following data:</u>
- Thrust = 180 Newton.
- Time = 30 seconds.
To determine the impulse that was produced by this aircraft jet engine:
<h3>How to calculate impulse.</h3>Mathematically, impulse is given by this formula:
<u>Where:</u>
- F is the force or thrust.
- t is the time measured in seconds.
Substituting the given parameters into the formula, we have;
Impulse, I = 5,400 Ns.

Answer:
Step-by-step explanation:
Simple regression was employed to establish the effects of childhood exposure to lead. THe effective sample size was about 122 subjects. THe independent variable was the level of dentin lead (parts per million). Below are regressions using various dependent variables.
Calculate the t statistic for each slope, at significance level = 0.01.
Dependent Variable R2 Estimated Std. t calculated p-value Differ from 0?
