Answer:

To verify that they're polarized, he could hold the two lenses perpendicular (90 degrees) to each other, one lens in front of the other, and point it at a light source. If no light passes through then the lenses are polarized

Which law of motion accounts for the following statement? "An apple accelerates as it falls from a tree."
belka [17]
Although one could definitely directly connect an "apple falling" with Newton's first law of motion, which is gravity, since the question states about acceleration, then we can relate the statement to Newton's second law of motion, the law of acceleration.

A 2200 kg SUV traveling at 23.9 m/s can be stopped in 0.16 s if it hits a concrete wall. Assume that a 60 kg person was in the c
Jlenok [28]

Answer:

8962.5 N

Explanation:

From fundamental kinematics equations, acceleration, a is given by a=\frac {v-u}{t} where v is final velocity, u is initial velocity and t is time

We also know that force is a product of mass and acceleration of an object and substituting a=\frac {v-u}{t}  in the formula F=ma we obtain

F=ma=m\frac {v-u}{t}  where m is the mass of the body

F=60\times\frac {0-23.9}{0.16}=-8962.5 N

Therefore, the force is 8962.5 N

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
