Answer:
Explanation:
At 5 s the body has travelled 10 m.
Between 5 s and 10 s, the body reached 30 m.
Distance travelled = 30 m - 10 m = 20 m
Time = 10 s - 5 s = 5 s
The silk will D)repel one another because the Amber charged them the same and the same charge will repel each other.
Answer:5
Explanation:In order to be able to say how many sig figs are used for the measurement 811.40 g, you need to know that
<span><span>
non-zero digits are always significant</span><span>
a trailing zero that follows a decimal point and a non-zero digit is always significant</span></span>
In your case, the measurement
<span>811.40</span>
has four non-zero digits and one significant trailing zero.
<span><span><span>8,1,1,4</span>→</span> non-zero digits<span><span>8,1,1,</span>0→</span> significant trailing zero</span>
Therefore, you can say that this measurement has <span>five significant figures</span>
<span>811.40→</span> <span>five significant figures</span>
Mass of H2O=2.01568g+15.9994g=18.01508gmol H2O.
Step 2: Multiply 1.24 mol H2O with the molecular mass. 1.24 mol H2O x 18.01508gmol H2O = 22.3 g H2O.
