Answer:

 6.9.

Explanation:

In case of product of two physical quantities with errors , the rule is that the product will contain error equal to the sum of percentage errors of the two physical quantities. Foe example  P contains 2% error and Q contains 3% error then P X Q will contain 2 +3 = 5 % error.

(21 ± 1.14 %) x (14±1.9%)

Total percentage error in the result of product

1.14 + 1.19 = 2.33 %.

Produce value = 21 x 14 = 294

percent of error in it = 2.33%

value of error

= 2.33% of 294

= 6.8502 or 6.9.

In the periodic table, the properties repeat in what direction?​
pogonyaev

Answer:

Left to right and top to bottom

Explanation:

On the periodic table, the properties repeat from left to right and from top to bottom.

Periodic properties have a pattern from the top to the bottom or down a group or family.

Also, across the period from left to right, they also show a repeating pattern.

  1. Certain properties increase from left to right and decreases from top to bottom. E.g. electronegativity.
  2. Also, some properties decreases from left to right and increases from top to bottom e.g. atomic radius.
