Explanation:
Find the motion diagram attached for the illustration:
Distance is the length of path traveled from the start to the finish. In measuring distance, we wall through the path from start to the finishing point. Distance is a scalar magnitude that has magnitude but no direction.
Displacement is distance that is taken between the start and finishing point. It is a vector quantity that has magnitude and measures direction.
To find the distance;
Distance = 5km + 7km = 12km
Displacement:
Using pythagoras theorem;
Displacement = √7² + 5² = 8.6km
Direction:
sin(bearing ) =
bearing = arcSin 0.5814 = 035.6°
Displacement is 8.6km in a direction 035.6°

I think its high. I just looked it up and it said stuff about how it is closely related to some gases.
Answer:
15.3 %
Explanation:
Step 1: Given data
- Mass of the sample (ms): 230 g
- Mass of carbon (mC); 136.6 g
- Mass of hydrogen (mH): 26.4 g
- Mass of nitrogen (mN): 31.8 g
Step 2: Calculate the mass of oxygen (mO)
The mass of the sample is equal to the sum of the masses of all the elements.
ms = mC + mH + mN + mO
mO = ms - mC - mH - mN
mO = 230 g - 136.6 g - 26.4 g - 31.8 g
mO = 35.2 g
Step 3: Calculate the mass percent of oxygen
%O = (mO / ms) × 100% = (35.2 g / 230 g) × 100% = 15.3 %
Answer:
I think <em><u>bar graph</u></em> is the appropriate way to present the data.
