The wave oscillates in a single plane. so the answer would be (c) i think
True as the independent variable is over the dependent variable and controls it as the dependent relies on the independent.
I believe it is C i am not sure
Answer: F = 102141N
Explanation: <em><u>Newton's 2nd Law</u></em> states that a force can change the motion of a body. The relation is given by
F = m.a
whose units are:
[F] = N
[m] = kg
[a] = m/s²
Jenny's car, at the moment of the break, had acceleration:
![a=\frac{\Delta v}{\Delta t}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B%5CDelta%20v%7D%7B%5CDelta%20t%7D)
![a=\frac{11}{0.14}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B11%7D%7B0.14%7D)
a = 78.57 m/s²
Then, Force is
F = 1300*78.57
F = 102141 N
<u>Jenny's car experienced a force of </u><u>magnitude 102141N.</u>
