About 2 to 5 centimeters per year (1 to 2 inches per year), about the same speed that your fingernails grow. We know, then, that the outermost part of Earth consists of a series of large slabs (tectonic plates; lithospheric plates) that move slowly over the globe, powered by flow in the interior mantle
Answer:
1: is A
2: is C
Explanation:
1: because all other option would imply that the truck was not moved from from its previous position due to the lack of work / force exerted by the car
2: this is because the less dense ball will have less opposing force action on it causing it to move / accelerate / go at a faster speed
The correct expression for the maximum speed of the object during its motion is 
.
<h3>
Maximum speed of the object</h3>
The maximum speed of the object is determined using the following formulas;
v(max) = Aω
where;
- A is the amplitude of the motion
- ω is angular speed
The maximum speed of the object can also be obtained from the maximum net force on the object,
F = ma
where;
- F is the maximum net force
- a is the acceleration
- m is mass of the object
F = m(v/t)
mv = Ft
v = Ft/m
Thus, the correct expression for the maximum speed of the object during its motion is .

Answer:
B. tinkering, presenting, testing
Explanation:
In technological designs, some actions that are part of a system of methodical tests are grouped as technological process. Technological process is defined as the ordered procedure or steps to be followed in order to successfully accomplish a task (e.g project).
The project must have been created and refined i.e tinkered to ensure it gives an expected result or outcome i.e the project should give a solution to the problem that it was designed for. Which would undergo presentation and testing before it can be approved.
C. a prediction
you make the prediction yourself whereas units, independent and dependent variables are all needed for you to read the graph
