Answer:
The period is
Explanation:
From the question we are told that
The extension of the spring is
The first weight applied is
The second weight applied is
The second extension is
The spring constant of the spring is mathematically evaluated as
substituting values
We are told that
19 N extended the spring to 33 m
Then W N will extended it by 17 m
Therefore
Generally the period of the oscillation is mathematically represented as
where M is the mass of the W which is mathematically evaluated as
substituting values
Answer:
The acceleration is 4, 8 m/s2
Explanation:
We calculate the acceleration, with the data of mass and force, through the formula:
F= m x a ---> a= F/m
a= 435 N/90 kg 1N= 1 kg x m/s2
a= 435 kg x m/s2/ 90 kg
a= 4,8 m/s2
The answer is true
It wouldn’t be false, it wouldn’t make any sense for it to be false
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.

To solve this problem we will apply the considerations of equilibrium on a body, we will decompose the tensions into their respective components and apply the sum of forces and solving equations for the given system.
According to the graph, the sum of the horizontal components would be
The sum of the vertical components is
Therefore the net force on the new vine is 366.2N
