Answer:
Reptiles have an enormous number of extremely minuscule hairs on the stack of their feet called setae. These little cushions subsequently radically increment the surface zone and come in close contact with the surface on which the reptile is creeping, so the Van der Waals forces kick in.

Connie flew from Phoenix to flagstaff, a distance of 180 miles at a constant speed of 180 miles per hour. She then returned to the same airport at a cj stand speed of 90. Miles per hour. What was connies average speed in miles/ hour
Answer:
Average Velocity = 120 mi/h
Explanation:
First we need to calculate the time taken by Connie to complete first half from Phoenix to flagstaff. So, we use:
s₁ = v₁t₁
where,
s₁ = distance from Phoenix to flagstaff = 180 miles
v₁ = speed of travel from Phoenix to flagstaff = 180 mi/h
t₁ = time taken to travel from Phoenix to flagstaff = ?
Therefore,
180 miles = (180 m/h)t₁
t₁ = 1 h
Now, we calculate the time for the return trip
s₂ = v₂t₂
where,
s₂ = distance from flagstaff to Phoenix = 180 miles
v₂ = speed of travel from flagstaff to Phoenix = 90 mi/h
t₂ = time taken to travel from flagstaff to Phoenix = ?
Therefore,
180 miles = (90 m/h)t₂
t₂ = 2 h
Now, we find total time:
t = t₁ + t₂
t = 1 h + 2 h
t = 3 h
and the total distance was:
s = s₁ +s₂
s = 180 mi + 180 mi
s = 360 mi
So, the average velocity will be:
Average Velocity = s/t
Average Velocity = 360 mi/3 h
Average Velocity = 120 mi/h

A candle’s wick is the fabric string that holds the flame, and it burns down at a constant slow pace when the candle is lit. The wick is usually surrounded by wax. Which is the most important property of covalent compounds that makes them useful for making candle wax? a low boiling point a low melting point a high boiling point a high melting point
Answer:
the answer is a low melting point
Explanation:
on edge
Low melting point is the most important property of covalent compounds that makes them useful for making candle wax.
A molecule created by covalent bonding whereby the atoms possess one or much more pair of valence electrons is referred to as a covalent compound. Covalent compounds or ionic compounds are the two groups into which chemical compounds are often divided.
Ionic compounds are composed of atoms or molecules that have gained or lost electrons, causing them to become electrically charged. Ionic compounds are created when ions with opposing charges come together, typically when a metal interacts with a nonmetal. Low melting point is the most important property of covalent compounds that makes them useful for making candle wax.

20 g of water (specific heat of water is 4.18 J / g °C) undergoes a temperature change from 25° C to 20° C. How much heat energy moved from the water to the surroundings?
Answer:
418J
Explanation:
Given parameters:
Mass of water = 20g
Specific heat capacity of water = 4.18J/g°C
Initial temperature = 25°C
Final temperature = 20°C
Unknown:
Amount of heat lost to the surroundings = ?
Solution:
The amount of heat lost to the surrounding is the same as the quantity of heat needed to take down the temperature of the water.
Now, to solve this problem, use the mathematical equation below;
H = m c (T₂ - T₁)
H is the amount of heat
m is the mass
c is the specific heat capacity
T is the temperature
1 and 2 are initial and final states.
Now insert the parameters and solve;
H = 20 x 4.18 x (20 - 25)
H = -418J
The quantity of heat the moved from water to the surrounding is 418J

Determine the components, the magnitude and the angle (counter-clockwise with respect to the positive x axis) of the resultant vector, R = B + C. Given: 0 Vector B: magnitude = 5.00 units, angle = 115 . 0 Vector C: magnitude = 4.00 units, angle = 255 .
Answer:
Explanation:
We shall represent vector B and C in terms of i and j .
B = 5 cos115 i + 5 sin115 j
= -2.11 i + 4.53j
Similarly
C = 4 cos255 i + 4 sin225 j
= -1.04 i -3.86 j
R = B + C
= -2.11 i + 4.53j -1.04 i -3.86 j
= -3.15 i + .67 j
magnitude of R
= √( 3.15² + .67² )
= √( 9.92 +.45 )
= 3.22
Angle Ф
TanФ = - .67 / 3.15
= - .21
Ф = - 12⁰
= 180 - 12
= 168 degree counterclockwise from positive x axis.

A 1200kg car traveling at 45m/s slams on its breaks and slides to a stop. If the coefficient of kinetic friction between the car and the road is 0.85 determine how far the car slides
Given :
A 1200 kg car travelling at 45 m/s slams on its breaks and slides to a stop.
If the coefficient of kinetic friction between the car and the road is 0.85 .
To Find :
How far the car slides.
Solution :
Acceleration is given by :
[tex]ma = \mu_kmg\\\\a = \mu_kg\\\\a = 0.85\times 10\ m/s^2\\\\a = 8.5\ m/s^2[/tex]
Distance covered is :
[tex]2as=u^2-v^2\\\\s = \dfrac{u^2-v^2}{2a}\\\\s=\dfrac{45^2-0^2}{2\times 8.5}\\\\s=119.12\ m[/tex]
Therefore, distance covered is 119.12 m.
Hence, this is the required solution.
