Answer:
Precise but not accurate
Explanation:
Precision and accuracy are two very different terms in science, although they may be used interchangeably in everyday life. Precision refers to how close a set of values are to one another, and in this case, because the targets are so close to one another, they are very precise. However, they are not so accurate because they are all far from the bull's eye, the target.
Cheers.
Answer:
Given that W=mg:
The weight of the box would be 50 N taking the value of 'g' as 10ms-2. Taking the value of 'g' as 9.8ms-2, the weight of the box would be 49 N.
(N = Newtons)
Answer:
Molecular formula = P₄O₁₀
Explanation:
Given data:
Empirical formula = P₂O₅
Gram molecular mass = 284 g/mol
Molecular formula = ?
Solution:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = 2 ×31 + 5× 16 = 142
n = 284 / 142
n = 2
Molecular formula = n (empirical formula)
Molecular formula =2 (P₂O₅)
Molecular formula = P₄O₁₀
The Universe
Is Not shrinking
Is Not Expanding
It Does contain billions of galaxies
And it is Not about 10 billion years old
Hope this Helps. :)
