Answer:
4Joules
Step-by-step explanation:
According to Hooke's law which states that extension of an elastic material is directly proportional to the applied force provide that the elastic limit is not exceeded. Mathematically,
F = ke where
F is the applied force
K is the elastic constant
e is the extension
If a spring exerts a force of 6 N when stretched 3 m beyond its natural length, its elastic constant 'k'
can be gotten using k = f/e where
F = 6N, e = 3m
K = 6N/3m
K = 2N/m
Work done on an elastic string is calculated using 1/2ke².
If the spring is stretched 2 m beyond its natural length, the work done on the spring will be;
1/2× 2× (2)²
= 4Joules
Answer:
The length of the other piece is 38 inch.
Step-by-step explanation:
Given:
A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other.
Now, to find the length of the other piece.
Let the length of the other piece be 
.
And the length of one piece be 
.
The total length of the pipe = 
According to question:
⇒
<em>Dividing both sides by 5 we get:</em>
⇒
Therefore, the length of the other piece is 38 inch.
Answer:
(x,y) = (6/5, 38)
Step-by-step explanation:
y = y right?
so, you just substitute both of those equations
26+10x = 44-5x
26 -44 = -5x -10x
x = 6/5
then substitute x into ANY of these two equations
let's say we want the second one
y = 44 - 5 × 6/5
y = 38
I'm not sure but I think that first number there might be a 20 and not a 26. If that's true then, solving the same way you'd have
(x,y) = (8/5, 36)
