<u>Answer:</u>
"Where friction or rubbing results in the transfer of electrons between particles, objects can become negatively or positively charged."
<u>Explanation:</u>
The motion resistance of one moving object with respect to another is called as "Friction". It isn't a basic force, like gravity or electromagnetism. Alternatively, scientists believe it is the product of the electromagnetic attraction in two touching surfaces between charged particles.
The friction have formula:
Friction force (<em>f </em>) = coefficient of friction × normal force (N)
For an instances when one ride a bicycle, an example of rolling friction is the contact between the wheel and the way.
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
Answer
The type of boundary formed when lithospheric plates collide is called Convergent boundary
Explanation
When plates of the lithosphere collide, they form a sub-duction zone where the denser plate will be subdued underneath the less dense one. The one subdued later melts and get destroyed. This boundary occurs when; ocean crust meets ocean crust, when oceanic and continental crust meet and where continental crust meets continental crust.

Answer:
6) 2.6 m/s, 31°
7) 9.2 m/s
8) 1.2 s
Explanation:
I'll do #6, #7, and #8 as examples. You can solve #9 using the equation from #7, and #10 using the equation from #8.
6) Take north to be +y and east to be +x.
Given:
vₓ = 2.2 m/s
vᵧ = 1.3 m/s
Find: v
v² = vₓ² + vᵧ²
v² = (2.2 m/s)² + (1.3 m/s)²
v ≈ 2.6 m/s
θ = atan(vᵧ / vₓ)
θ = atan(1.3 / 2.2)
θ ≈ 31°
7) Given:
Δy = -4.3 m
v₀ = 0 m/s
a = -9.8 m/s²
Find: v
v² = v₀² + 2aΔy
v² = (0 m/s)² + 2 (-9.8 m/s²) (-4.3 m)
v ≈ 9.2 m/s
8) Given:
Δy = -6.7 m
v₀ = 0 m/s
a = -9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
-6.7 m = (0 m/s) t + ½ (-9.8 m/s²) t²
t = 1.2 s
