The energy stored in the spring is 2.25 J.

Given that the energy stored in a spiral spring is E = 1/2 k e^2

Where;

E = energy stored in the spring

k = force constant

e = extension

We can obtain the force constant as the slope of the graph;

k = 25 - 5/0.5 - 0.1

k = 20/0.4

k = 50 N/m

Substituting into the equation when e = 0.3,

E = 1/2 × 50 × (0.30)^2

E = 2.25 J

The term
stellarik [79]

Answer:

C. simple

The term that refers to the fact that an epithelial tissue has only one layer of cells is simple epithelial.

Explanation:

Epithelial tissues are thin tissues that cover all the exposed surfaces of our body.

Based on the number of cell layers, the simplest classification of epithelial tissue is:

a. Simple Epithelial Tissue

When the epithelial tissue consists of a single layer of cells, it is called simple epithelial tissue.

b. Stratified Epithelial Tissue

When there are two or more layers of cells in epithelial tissue, it is called stratified epithelial tissue.

Cuboidal epithelial is also a type of simple epithelial tissue.

Pseudostratified is another type of epithelial tissue which falls in neither simple nor stratified category. They consists of a single layer but the positioning suggests it is stratified.

There are 3 types of epithelial tissues based on their shape:

a. Squamos epithelial tissue

b. Cuboidal epithelial tissue

c. Columnar epithelial tissue

If you increase the weight of an object, the frictional force increases but the coefficient does not change why
aleksandr82 [10.1K]

Answer:

The coefficient of friction should in the majority of cases, remain constant no matter what your normal force is. When you apply a greater normal force, the frictional force increases, and your coefficient of friction stays the same. Here's another way to think about it: because the force of friction is equal to the normal force times the coefficient of friction, we expect (in theory) an increase in friction when the normal force is increased.

One more thing, the coefficient of friction is a property of the materials being "rubbed", and this property usually does not depend on the normal force
