Answer:
23.99N
Explanation:
Given:
Pressure created by the heart = 120mm of hg
converting the pressure into the standard unit of N/m²
1mm of hg = 
now, 120 mm of hg in N/m² will be
120mm of hg = 
also
given effective area = 15.0 cm² = 15 × 10⁻⁴m²
Now,
Force = Pressure × Area
thus,
Force exerted will be =
× 15 × 10⁻⁴m²
or
Force exerted will be = 23.99N
Valence electrons are required for certain bonding processes. Without them you cannot bond with certain elements. For example, carbon bonds really well with carbon because it has the same amount of valence electrons. However carbon would not bond well with uranium due to the massive differences in valence electrons. Hope this helps!
Answer:
The left train travels 2378 m until it reaches the meeting point.
Explanation:
The equation for the position of the trains is the following:
x = x0 + v · t
Where:
x = position at time t
x0 = initial position
v = velocity
t = time
If we place the origin of the frame of reference at the initial position of the left train, the right train will be at an initial position of 4744. 6 m relative to the left train. The velocity of the right train will be negative because it will be heading towards the origin.
At the meeting point, the position of both trains is the same:
x left train = x right train
x0₁ + v₁ ·t = x0₂ + v₂ · t
0m + 29 m/s · t = 4744.6 m - 29 m/s · t
58 m/s · t = 4744.6 m
t = 4744.6 m / 58 /s
t = 82 s
The position of the left train at that time will be:
x = x0 + v · t
x = 0 m + 29 m/s · 82 s
x = 2378 m
The left train travels 2378 m until it reaches the meeting point.
