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%.
Time= v*sintheta/g = 10*1/9.8= 1.02s therefore h=1/2*9.8*(1.02)^2= 5.10m
The answer is A) <span>The death rate begins to fall, but birth rates remain high for a time.</span>
We will apply the equation:2as = v² - u²v = √(2as + u²)v = √(2 x 4 x 400 + 13²)v = 58 m/s
When you lay down your weight is distributed over a much larger surface area than while standing. You are putting a much greater force on a much smaller area standing.
