Diagram of the dermis

1 answer:

6 0

Unlike the epidermis, this layer is connected to the blood and lymph supply as well as the nerves. Running through the dermis are sweat and sebaceous glands, hair follicles and muscles cells. Fibroblasts: responsible for the production of areolar tissue, collagen and elastin.

Answer:

I believe it is not a chemical change for the components are not changing.

This excerpt from thoughtco.com states that for it to be a chemical change, the atoms would be rearranged.

<em>In other words, a chemical change is a chemical reaction involving the rearrangement of atoms. While a physical change can often be reversed, a chemically change typically cannot be, except through more chemical reactions. When a chemical change occurs, there is also a change in the energy of the system.</em>

So, in this case, they are not being rearranged, just combined to form one big fruit salad.

Which answer is a scientifically accurate description of velocity?

Tcecarenko [31]

The boat traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

Explanation:

A boat traveling from the dock northward to a 200m mark in the bay in less than 5minutes giving the passengers several more hours to fish is a typical and best example of velocity description.

Velocity is the displacement of a body divided by the time taken.

Velocity = $\frac{displacement}{time}$

Displacement is the distance covered in a specific direction. Time is duration of the travel.

Velocity is a vector quantity that has both magnitude and direction. This implies that the value of velocity is recorded with a directional attribute.

We can say velocity is the speed of a body in a given direction

Only the last option gives the displacement of the body and the duration it traveled.

In a game of pool the cue ball is rolling at 2.00 m / s in a direction 30.0° north of east when it collides with the eight ball

victus00 [196]

Answer:

$v_{f1}=1.758m/s$

Explanation:

The collision is elastic so we can use the conservation of momentum

$P_i=P_f$

$m_1*v_1+m_2*v_2=m_1*v_{f1}+m_2*v_{f2}$

Describe the motion in axis x'

$170g*2.0m/s*cos(30)+156g*0m/s=170*cos(10)*v_{f1}+156g*0m/s$

$294.44 g*m/s=167.41g*v_{f1}$

$v_{f1}=1.758m/s$

Describe the motion in axis y'

$170g*2.0m/s*sin(30)=170g*1.75m/s*sin(10)+156*v_{f2}$

$v_{f2}=1.55m/s$

What question could you ask about kinetic energy which will include the variables that affect it?

Juli2301 [7.4K]

KE= (1/2) mv²

So, the variables we need to include in our question would be a varable for a mass(m) of an object at some velocity(v).

My Answer:

(This is just an example question, yours can be different)
What is the Kinetic Energy experienced by an bouncy ball rolling at 7m/s (that's your velocity) across a frictionless surface that has a mass(m) of 10 grams?
