Answer:
An opposing force caused by friction produced a lower acceleration than calculated.
Explanation:
3.0 typically is only felt by people who are resting or on the up stairs of buildings. 6.0 is more intense. I would say a 6.0 can produce high intensity levels. A 6.0 can damage buildings of good design and structure. Damagable in poorly built or badly designed structures. Some chimneys may be broken.
Answer:
9.43*10^3 year
Explanation:
For this question, we ought to remember, or know that the half life of carbon 14 is 5730, and that would be vital in completing the calculation
To start with, we use the formula
t(half) = In 2/k,
if we make k the subject of formula, we have
k = in 2/t(half), now we substitute for the values
k = in 2 / 5730
k = 1.21*10^-4 yr^-1
In(A/A•) = -kt, on rearranging, we find out that
t = -1/k * In(A/A•)
The next step is to substitite the values for each into the equation, giving us
t = -1/1.21*10^-4 * In(5.4/15.3)
t = -1/1.21*10^-4 * -1.1041
t = 0.943*10^4 year
Boyle's law states that in an ideal gas system, pressure and volume have an inverse relationship when the temperature remains constant. So B.
Question 1: Amount of energy
Question 2: Freezing ice
Question 3: Chemical change
Question 4: More energy is given off by the new bonds formed than is needed to break the original bonds.
Question 5: The resulting mass would be 35 grams.
