Answer:
When any rock falls under gravity, the rock will move in vertical downward direction towards the centre of earth under a constant
Explanation:
Rodney explicitly referred to Africa as "underdeveloped", not "developing", because of its past and present of exploitation that has created its socio-economic position. Underdevelopment is not defined by a lack of resources but an uneven and, he argued, unjust distribution of the wealth of those resources.
Concept development is a set of activities that are carried out early in the systems engineering life cycle to collect and prioritize operational needs and challenges, develop alternative concepts to meet the needs, and select a preferred one as the basis for subsequent system or capability development...

Analyzing the relationship between variables by using regression allows a researcher to evaluate whether or not one variable will predict the outcome of another. This statement is True.
Regression analysis allows relationships or correlations between the data to be analyzed. Analyzing data helps researchers understand the results of the experiments they are conducting. Regression analysis allows you to interpret the values of other variables. If the variables are known, researchers can use the data to predict outcomes without performing an actual experiment.

The angle turned is obtained as 3.77 rads.
<h3>What is the angle of rotation?</h3>
We have the following information about the disk;
velocity 1= 7200 RPM
velocity 2 = 0 RPM
time taken = 0.01 seconds
We must convert from RPM to rad/s using the relation;
2π·7200/60 = 754 rad/s
Using;
θ = ωavt
θ = (754 rad/s + 0 rad/s)/2 * 0.01 seconds
θ = 3.77 rads
