Answer:
5√(10/x)
Step-by-step explanation:
√10^3/4x
= √10^3 / √4x
= 10√10 / 2√x
=(10/2)√(10/x)
= 5√(10/x)
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.
<h3>Answer: B) 25 = 10 + w</h3>
I think D because don't proportional lines go straight or sum
