Because the tomato did not chemically changed it was only physically altered.
Hope this helps! :D
Answer:
300 nm
Explanation:
R = Gas constant = 8.314 J/molK
r = Atomic radii = 
d = Atomic diameter = 
At STP
T = Temperature = 273.15 K
P = Pressure = 100 kPa
= Avogadro's number = 
The mean free path is given by
The answer that best represents the mean free path for gas molecules is 300 nm
Answer:
fr = m v₀² / 2 (x₁-x₀)
Explanation:
a) For this exercise we use Newton's second law
X axis
- fr = ma
Y Axis
N-W = 0
N=W
let's look for acceleration with expressions of kinematics
v² = v₀² - 2 a Δx
at the point where stop v = 0
a = v₀² / 2 Δx
let's replace
-fr = m (- v₀² / 2 (x₁-x₀))
fr = m v₀² / 2 (x₁-x₀)
b)they ask for the same
in this case part of rest
v₁² = 0 + 2 a Δx
a = v₁² / 2ΔX
we write Newton's second law
F - fr = m a
fr = F - ma
fr = F - m v₁² / 2Δx
