Answer:
200 N/m
Step-by-step explanation:
Rearranging the formula F = kx, you find that k = F/x. For the first spring,
F = 36 N and x = 0.06 m (6 cm). So the spring constant, F/x, is 36N/0.06m = 600 N/m
For the second spring, F = 36 N and x = 0.09 m. F/x = 36N/0.09m = 400 N/m
The difference between these values is 200 N/m, and that's the answer.
2 equivalent expressions always have the same amount. They always equal the same number.
Answer:
2x + (-2x + 3) = 3
2x - 2x +3
0 + 3
3
2x-7 + (-2x) = -7
2x -2x - 7
0 -7
-7
-(5x -1) + 5x = 1
-5x +1 + 5x
-5x + 5x + 1
0 + 1
1
Step-by-step explanation: In addition, the parentheses help identify the individual addends. If adding a negative number, it is the same as subtracting. If there is a negative sign outside the parentheses, as in example c, you must distribute it: the signs of the numbers within the parentheses must be reversed when the parentheses are removed.
You add 2 to each of the three sides.
okay?
-11< -x+2< 8
-2 -2 -2
--------------------
-13< -x <2
Divide by negative 1
-13< -x <2
--------------
-1
Switch the signs direction
13> x > -2
