Answer:
12 cm
Step-by-step explanation:
To calculate the length of a spring with a 2 kg load, compare the displacement of a 1 kg load and adjust accordingly.
When a 1 kg load is suspended from the spring, the spring which is 6 cm stretches to 9 cm. This is 3 cm longer due to the weight. If you attach a weight which is twice as much then the displacement will be twice as much. Instead of stretching an additional 3 cm, it will stretch 2*3 = 6 cm. Add this to the length of the spring and it stretches in total 6 + 6 = 12 cm.
Answer:
65 because 12 plus 9 is 21 then 3 times 21 is 65

Answer:
d
Step-by-step explanation:
You could just do process of elimination. So for the first one if you add them all up you would get 3,452 which is not correct, for the second one would not be correct since after you do 3 times 104 you can see it is wrong, for c it is also wrong since there is a 30 not a 30,000, for d it is correct since if you write it out is is 30,452, for E it is not correct just by looking at the problem, and for F it cannot be correct since it does not be the right answer
Rewrite the percentage as a decimal:
8% = 8/100 = 0.08
Multiply the previous result by 24000:
24000*0.08 = $1920
