Answer:
23.52 N
Explanation:
Using the Hydraulic Press formula
since the the liquid in an hydraulic press cannot be compressed
P₁ ( pressure at the piston 1) = P₂ ( pressure at piston 2)
P₁ = F₁ / A₁ where F₁ represent the weight of the car and F₂ represent the force applied at the 1 cm end and A₁ and A₂ are the area of the piston respectively
P₂ = F₂ / A₂
F₁ / A₁ = F₂ / A₂
(F₁/A₁) × A₂ = F₂
F₁ = 1500 kg × 9.8 m/s² = 14700 N
A₁ = πR² = π ( 0.25)² where R = 25 cm = 0.25 m for the larger piston
A₂ = πr² = π ( 0.01)² where r = 1 cm = 0.01 m
(F₁/A₁) × A₂ = F₂
F₂ = ( 14700 N / ( π 0.0625)) ×π (0.01)² = 23.52 N
Answer:
2400 km
Explanation:
30km for 1hr
Need up to 80 hrs , multiply both 80 and 30
So its 2400km
The decrease in energy in the hydrogen molecule is what allows its formation on Earth, but in stars the great energy of the explosion has a kinetic energy so great that electrons cannot bind to another atom, which is why hydrogen has a single atom.
The hydrogen molecule is a form that two hydrogen atoms share their electrons decreasing the total energy of the molecule, this bond has a covalent and hydrogen bonding characteristic.
In a stellar explosion, the energy released increases the energy of the hydrogen atom, for which we have two possibilities:
- Its electron is lost, so we are in a single proton, in the case of structures where the proton and the elector are
- The hydrogen atom remains but the energy of the atom is very high so the kinetic energy of the electron prevents the electron from being shared by the other atom and the molecule cannot be formed.
When the atoms are thrown into space, the separation between them is so high that it does not allow electrons to be shared and molecules cannot be formed either.
In conclusion, the decrease in energy in the hydrogen molecule is what allows its formation on Earth, but in stars the great energy of the explosion has a kinetic energy so great that electrons cannot join another atom, which is why the hydrogen has only one atom.
