Answer:
B
Explanation:
to see how fast she is going per second, you would have to divide the distance traveled by the seconds it took to travel the distance
Answer:we can calculate the answer by following steps;
Explanation:
F=190N
d=3.7m
w=?
we have,
w=fxd
=190nx3.7m
=703j#
We are told that 4.0
complete waves pass a fixed point in 10 seconds. Using these data, we can find the frequency of the wave, which is given by the number of complete cycles per second:
![f=\frac{N}{t}=\frac{4}{10 s}=0.4 Hz](https://tex.z-dn.net/?f=%20f%3D%5Cfrac%7BN%7D%7Bt%7D%3D%5Cfrac%7B4%7D%7B10%20s%7D%3D0.4%20Hz%20%20%20)
Now we can find the period of the wave, which is the reciprocal of the frequency:
![T=\frac{1}{f}=\frac{1}{0.4 s}=2.5 Hz](https://tex.z-dn.net/?f=%20T%3D%5Cfrac%7B1%7D%7Bf%7D%3D%5Cfrac%7B1%7D%7B0.4%20s%7D%3D2.5%20Hz%20%20%20)
So, the correct answer is (3) 2.5 s.
