675 nM is 675 x 10⁻⁹ meter ... 0.000 000 675 meter .
That's 0.000 067 5 of one centimeter
0.000 675 of one millimeter
Answer:
true 1
2 is false 2. 3 . 4. 5
Explanation:
For this exercise, let's calculate the different parameters and analyze the corresponding statements.
the resistance of each wire
R = ρ
wire B.
has a diameter of d₀
therefore its radius is r₀ = d₀ / 2
the area is A = pi r₀²
A = π d₀²/ 4
we subtitle
Ro = ρ
R_b = R₀
wire A
the diameter is d = 2d₀
therefore the radius is r = d/2
r = d₀
resistance is
R_a = ρ
R_a = 4 R₀
when examining the answers
1 is true
4 is false
Now let's calculate the power
P = V I
V = I R
P = V² / R
as they indicate that the cables are connected in parallel, the voltage in them is the same, therefore the potency depends on the resistance
wire B
P = V² / R_b
P_b = V² / R₀
wire A
P_a = v² / R_a
P_a = V² / 4R₀
P_a = ¼ P_b
2 is false
in a parallel circuit the waves are the same therefore
3 False
ohm's law is
V = I r
I = V / R
wire B
I_b = V / R_b
I_b = V / Ro
wire
I_a = V / R_a
I_a = V / 4 Ro
I_a = ¼ I_a
5 is false
Answer:
Burning is a chemical process by which two atoms or molecules will combine with each other. In burning, the two atoms or molecules will combine and release energy. ... When the molecules combine and release energy, it is released in the form of heat and often light.

Answer:
0.00018784
Explanation:
= Initial length of cylinder = 0.26 m
= Change in length
= Outer radius =
= Inner radius =
m = Mass of arm = 57 kg
g = Acceleration due to gravity = 9.81 m/s²
A = Area
Y = Young's modulus =
When we divide stress by young's modulus we get compressional strain
Compressional strain of the humerus is 0.00018784
