Answer:
The correct option is D
Explanation:
In trying to achieve what the student wanted to see, which is to see the relationship between the weight the cord can hold and how long the cord will stretch. Since the origin of the graph is from zero, the value plotted on the vertical axis would be just the length caused by each weights. Thus, <u>the original length would have to be subtracted from the measured length to determine the actual length caused by the weight added to the cord</u>.
Answer:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

You have selected the correct answer and blobbed over it with your pencil.
I assume you must have looked at Saturn's average distance, found 1427,
divided that number by 6, got 237 and change, then looked at the others,
and found that 228 was the only one that's anywhere close.
GPE I am assuming is gravitational potential energy. I'll denote it as U for simplicity.
U = mgy
U = (70kg)(9.81m/s^2)(1m) = 686.7J
U = 686.7J
Hope this helps!

The density of olive oil is 0.911 g/cm^3 and the density of water is 1.000 g/cm^3.
To calculate the pressure of 1 cm of water,
1000 kg/m^3 * 9.8 m/s^2 * 0.01 m = 98.000 Pa
To calculate the pressure of 1 cm of olive oil
911 kg/m^3 * 9.8 m/s^2 * 0.01 m = 89.278 Pa
Now to calculate the pressure at the bottom of the container, simply add the products of how many cm of each fluid you have. So
21 * 98.000 Pa + 11 * 89.278 Pa = 2058 Pa + 982.058 Pa = 3040.058 Pa
So the pressure at the bottom of the container will be 3040. Pascals.</span>
