Force applied = F = 628 N
<span>Acceleration = a m/s² </span>
<span>Newton's 2nd law of motion : F = Ma </span>
<span> a = F/M -------- (1) </span>
<span>New mass of the crate = M1 = 3.8M kg </span>
<span>New acceleration = a1 = F/M1 = F/(3.8 M) ----- (2) </span>
<span>a1/a = {F/(3.8M)}/(F/M) = 1/3.8 = 10/38 = 5/19 ------- Answer</span>
The part of the question that says " x 10⁶ " means
" move the decimal point 6 places that way ===> ".
So take the 1.986 and do that to it.
If there aren't enough places to move the decimal point far enough,
add some zeros to the 1.986 before you move the point.
Explanation:
In 1911, Marie was awarded a second Nobel Prize in Chemistry for her discovery of the elements polonium and radium. In honor of the 100-year anniversary of her Nobel award, 2011 was declared the "International Year of Chemistry."
<span>Any substance that yields a hydrogen ion when placed in a water solution is called an acid.</span>
