Answer:
The initial acceleration is 0,221 m/s^2.
Explanation:
The answers are 'muscle shrinkage' and 'decreased muscle cavity'. This is why unhealthy astronauts cannot go to space because it can be detrimental to their health.
Answer:
Valence electrons are the electrons present in the outermost shell of an atom. You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table.
Explanation:
Answer:
W / A = 39200 kg / m²
Explanation:
For this problem let's use the equilibrium equation of / newton
F = W
Where F is the force of the door and W the weight of water
W = mg
We use the concept of density
ρ = m / V
m = ρ V
The volume of the water column is
V = A h
We replace
W = ρ A h g
On the other side the cylinder cover has a pressure
P = F / A
F = P A
We match the two equations
P A = ρ A h g
P = ρ g h
P = 39200 Pa
The weight of the water column is
W = 1000 9.8 4 A
W / A = 39200 kg / m²
Answer:
The force bumper at 0.200m
F=2722.5 N
Explanation:
Using the energy theorem of work
W=ΔK
W=F*d
ΔK=
ΔK=F*d=
