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
Labels that belong in regions marked X and Y are;
A) X: Maintains magnetic properties in the presence of another magnet
Y: Is made from magnetically hard ferromagnetic material
Answer:
Both feel same magnitude force.
Explanation:
Given that
Mass of father = 100 kg
Mass of daughter = 50 kg
From the third law of Newtons :
Every action have it reaction in opposite direction.It means that if any object apply a force on the other object then first object also feel force of same magnitude but in opposite direction.
It means that both father and her daughter will feel same magnitude of same but in opposite direction.
Acceleration=9.81m/s^2
initial velocity=0m/s
time=.28s
We have to find final velocity.
The equation we use is
Final velocity=initial velocity+acceleration x time
Vf=0m/s+(9.81m/s^2)(.28s)
Vf=2.7468m/s
We would round this to:
Vf (final velocity)=2.7m/s
The approximate value for the distance between the two points is <span>3.162277663.16227766</span>.
<span><span>√10</span>≈<span>3.16227766
