Answer:
+1/7
Step-by-step explanation:
One approach to evaluating this would be to rewrite it as:
-2 -5
------ * --------- .
10 7 This reduces to:
2
--------- = +1/7
2(7)
Figure out 5% of 30,000: .05 x 30,000 = 1,500
Multiply 1,500 by the number years, but subtract the first year (as you don't receive a bonus) : 1,500 x 39 = 58,500
Now add the bonus with the initial salary: 58,500 + 30,000 = 88,500.
THE ANSWER IS $88,500!!! :)
1/10 would be 0.1 dollars
To determine the answer of Part A draw the equilateral triangle and the to determine the coordinates of of the third charge use that triangle.
To calculate the gravitational field strength in part B from each of the charges use the following equation.
E=kcq/r2
If you would add those values then you can use the symmetry about the y axis to make the vector addition a litter easier.<span />
