A force of 0.8N stretches an elastic spring by 4cm. Calculate the elastic constant.

k= force/elongation=.8N/.04m= 20 N/m

Well, to find the elastic constant, we need to use Hooke's law, which states that the force exerted by a spring is directly proportional to the displacement it undergoes. So, we have F = kx, where F is the force, k is the elastic constant, and x is the displacement.

Now, we know that the force is 0.8N and the displacement is 4cm, which is 0.04m.

So, let's substitute the values into the equation: 0.8N = k * 0.04m.

Now, if we solve for k, we get k = 0.8N / 0.04m = 20N/m.

Therefore, the elastic constant is 20N/m.

But hey, don't let that number spring any surprises on you!

To calculate the elastic constant (k) of an elastic spring, we can use Hooke's law, which states that the force applied on a spring is directly proportional to the extension or compression of the spring.

The equation for Hooke's law is:

F = k * x

Where:
F is the force applied on the spring
k is the elastic constant (also known as the spring constant)
x is the extension or compression of the spring

In this case, we have:

F = 0.8 N (force applied on the spring)
x = 4 cm (extension of the spring)

To convert cm to meters, we divide by 100:

x = 4 cm / 100 = 0.04 m

Now we can rearrange the equation to solve for k:

k = F / x

Substituting the given values:

k = 0.8 N / 0.04 m

k = 20 N/m

Therefore, the elastic constant (spring constant) of the spring is 20 N/m.

To calculate the elastic constant (k), we can use Hooke's Law, which states that the force applied to an elastic material is directly proportional to the amount it stretches or compresses. The formula for Hooke's Law is:

F = k * x

Where:
F is the force applied, in Newtons (N)
k is the elastic constant, also known as the spring constant or stiffness constant
x is the displacement (change in length) of the spring, in meters (m)

In this case, we are given:
F = 0.8 N
x = 4 cm = 0.04 m

To calculate the elastic constant (k), we need to rearrange the formula:

k = F / x

Substituting the given values:

k = 0.8 N / 0.04 m

k = 20 N/m

Therefore, the elastic constant (k) is 20 N/m.
