Your voltmeter and your teacher are both right, but the water analogy of electricity can only go so far. One big drawback is that, unlike with water, there is no absolute voltage. .... Wherever you put the black lead is defined as "0V". .... flowing (i.e. the circuit is broken) you will not get this change in voltage.
Answer:
a. longitudinal
Explanation:
A longitudinal study examines a given group over a long period of time, so collecting data from the same group of 30 people over their lifetime certainly fits that definition. It's more like an evolution study.
A cross-sectional compares different groups at the same point in time. So, it's more like a survey.
A microgenetic is much focused in time, providing multiple data sets in a short time to examine rapid evolution of a subject.
An experimental study design will make interactions and experiments with the study group, while this is not the case here apparently, and experimental is usually for a much shorter period than a generation.
It is coming from your head... If you have common sense. or it could be coming from alcohol.
Answer:
uhhhh,I'm sorry maybe their just busy
Answer:
If the question is (2/3x) = -10,
x = -(1/15) = - 0.06667
The check is presented under the explanation below
If the correct question is (2/3)x = -10,
x = -15
The check is presented under the explanation below
Explanation:
If the question is rightly written as it is in the attached document,
(2/3x) = -10
We can cross multiply and obtain
2 = -10 × 3x
-30x = 2
x = -(2/30) = -(1/15) = - 0.06667
To check
(2/3x) = -10,
(2 ÷ 3x) = -10
2 ÷ 3(-1/15) = 2 ÷ (-1/5) = 2 ÷ (-0.2) = -10 (Correct!)
If the correct question is
(2/3)x = -10
Divide both sides by (2/3)
x = -10 ÷ (2/3)
x = -10 × (3/2)
x = -15
To check
(2/3)x = -10
If x = -15
(2/3) × (-15) = -10 (Correct!)
Hope this Helps!!!
