Answer: W = 0.8 J
Explanation:
At 0.12 m the force is 3.0 N
At 0.28 m the force is 7.0 N
The distance of stretch is 0.28 - 0.12 = 0.16 m
The AVERAGE force is (3.0 + 7.0) / 2 = 5.0 N
The work is
W = Fd = 5.0(0.16) = 0.8 J
or
A formula guy might find the slope of the line
k = 7 N / 0.28 m = 25 N/m
PS = ½kx²
PS = ½(25)0.28² - ½(25)0.12² = 0.8 J
or
A charts gal might realize that the work is the area under the curve between the limits
W = A = (0.28 - 0.12)[3.0 + ½(7.0 - 3.0)] = 0.8 J
or
A math guy might find an equation for the line and integrate between the limits.
y = 25x
W = for b = 0.12 and a = 0.28
W = 12.5x² | for b = 0.12 and a = 0.28
W = 12.5(0.28)² - 12.5(0.12)²
W = 0.8 J
Answer: you just know bro

Answer:
D is the correct answer! Hope this helps you!!!!
Explanation:
The next step to take is to used the scientific method to explore the observations she has made in order to discover the facts behind her observations. She should ask questions about the hotness of the pavement and form an hypothesis to support her observation. She should then set up an appropriate experiment to confirm her hypothesis. After the conduction of the experiment, she should analyze her results and then draw a conclusion.<span />
Each principal energy level has one sublevel containing one orbital, an s orbital, that can contain a maximum of two electrons. Electrons in this orbital are called s electrons and have the lowest energy of any electrons in that principal energy level.
