Volume = mass / density = 45.6/10.5 = .... L
Answer:
the use of non-renewable fuels, a dramatic increase in the rate of accidental death, the disconnection of local community, the decrease of local economy.
The periodic table shows the atomic number ( # of protons) and average atomic mass (weight of protons and neutrons combined). You can subtract the number of protons from the atomic mass of that element to find number of neutrons.
Mass of a model car you measured = 230 grams
Actual mass = 218 grams
Percent error = ?
First subtract the actual value from the value
you measured,
230 grams – 218 grams = 12 grams
Now divide 12 grams by the actual mass that is
218 grams:
12 / 218 = 0.055
Now multiply 0.055 with 100 to get the percent
error;
0.055 x 100 = 5.5%
So, the Percent error is 5.5%.
Answer:
Hello There. ☆~\《--_^■^_--》\~☆ The final velocity of the car A is -1.053 m/s. For an elastic collision both the kinetic energy and the momentum of the system are conserved.
