<u>Statement</u><u>:</u>
A non-deformed spring is 15 cm long. When a 2.0 N force is applied to it, its length becomes 19 cm.
<u>To </u><u>find </u><u>out:</u>
The spring constant of the spring.
<u>Solution:</u>
- Extension of the spring (x)
- = (19 - 15) cm
- = 4 cm
- = 0.04 m [since we have to find the answer in N/m]
- Let the spring constant of the spring be k.
- We know, the formula of spring force, i.e.,
- F = kx
- Putting the values in the above formula, we get
- 2 N = k × 0.04 m
- or, k = 2 N ÷ 0.04 m
- or, k = 50 N/m
<u>Answer</u><u>:</u>
<u>The </u><u>spring </u><u>constant</u><u> of</u><u> </u><u>this </u><u>spring </u><u>is </u><u>5</u><u>0</u><u> </u><u>N/</u><u>m.</u>
Hope you could understand.
If you have any query, feel free to ask.
The people of Florida are closest to the equator and also near 2 different bodies of water and have rivers running thru them as well salt water and fresh water. they need alot of freshwater due to monsoon seasons, hurricanes etc, its humid and hot there so naturally you need to water more often and frequently.
The hip is the kinetic chain checkpoint which controls the movement of the lower extremities and is denoted as option A.
<h3>
What is Hip?</h3>
This part of the body has a ball-and-socket joint and ensures adequate movement of the legs.
The legs and other parts such as ankle etc are referred to as the lower extremities thereby making it the most appropriate choice.

The formula written in the 3rd line above the picture is WRONG. Don't use it. Use the formula the way it's printed in the picture.
V = d / t
That means Speed = (distance) / (time)
The question tells us that v = 330 m/s
So you write 330 m/s in the equation in place of 'v', like this:
330 m/s = (distance) / (time)
The question also tells us that the time is 0.4 second
So you write 0.4 sec in place of 'time', like this:
330 m/s = (distance) / (0.4 second)
Finally, you take this, and multiply each side of the equation by (0.4 sec). Then it'll say
distance = (330 m/s) x (0.4 second)
As soon as you do that one single multiplication there with your pencil or your calculator, you'll have the distance.
This is either the 2nd or 3rd time you've posted this same exact question since last weekend. It can be solved THIS time exactly like the answers that were posted those other times.
The DOT in the picture is marked for the wrong choice. Use the formula that's printed in the picture, not copied above it.
