Answer: the same number of decimal places as the least precise value.
Explanation:
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the addition and subtraction is :
The least precise number present after the decimal point determines the number of significant figures in the answer.
For example: 12.1 + 3.245 = 15.3 as the least precise number 12.1 has one decimal place.
Thus William should write the sum of these two numbers by using the same number of decimal places as the least precise value.

Answer:
The three laws of motion were first compiled by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687. Newton used them to explain and investigate the motion of many physical objects and systems
Answer:
Explanation:
Start by finding the weight supported by the wheels, as we can then relate that to the total frictional force through the friction coefficient. This is given by:
W=mg
Substitute 1.00×, or 1,000, for m and 9.81 m/ for g. This gives us
W=(1,000)(9.81)
W=9,810 N
Since half the weight is supported by the wheels in question, we divide this by two, and the weight we will use is 4,905 N.
The frictional force is given by:
F=μW
Where μ is the friction coefficient and W is the weight, which we just calculated. The friction coefficient for rubber on dry concrete is given in Table 6.1 as (1.0). Substitute that for μ and 4,905 N for weight and we get the total frictional force as 4,905 N. Now we can find the acceleration by rearranging F=ma to get a=. Substitute our frictional force 4,905 N for F and our total mass 1,000 kg for m to get 4.9 m/.
