An object-spring system undergoes simple harmonic motion. if the mass of the object is doubled, what will happen to the period of the motion?

Answers

Answer 1
Answer:

The period of simple harmonic motion remains unchanged when the mass of the object is doubled.

What is simple harmonic motion?

Simple harmonic motion (SHM) is a type of periodic motion where an object oscillates back and forth around a fixed point in a regular and repeated manner. It is a special case of periodic motion, characterized by a restoring force that is proportional to the displacement from the equilibrium position. The classic example of SHM is a mass-spring system, where a mass is attached to a spring and is subjected to a restoring force proportional to the displacement from its rest position.

In SHM, the motion is always sinusoidal and the period of the motion is constant, which means that the time for one complete cycle of the motion remains the same. This type of motion is important in a variety of physical systems, including the vibration of mechanical systems, the oscillations of electrical circuits, and the motion of particles in a gravitational field.

In the Bohr model of the hydrogen atom, an electron moves in a circular path around a proton. The speed of the electron is approximately 2.03 106 m/s.(a) Find the force acting on the electron as it revolves in a circular orbit of radius 5.35 10-11 m.
whats the magnitude in N ?


(b) Find the centripetal acceleration of the electron.
whats the magnitude in m/s2

Answers

In order to answer these questions, we need to know the charges on
the electron and proton, and then we need to know the electron's mass. 
I'm beginning to get the creepy feeling that, in return for the generous
5 points, you also want me to go and look these up so I can use them
in calculations ... go and collect my own straw to make the bricks with,
as it were. 

Ok, Rameses:

Elementary charge . . . . .  1.6 x 10⁻¹⁹  coulomb
                                        negative on the electron
                                        plussitive on the proton

Electron rest-mass . . . . .  9.11 x 10⁻³¹  kg


a).  The force between two charges is

      F  =  (9 x 10⁹) Q₁ Q₂ / R²

          =  (9 x 10⁹ m/farad) (-1.6 x 10⁻¹⁹C) (1.6 x 10⁻¹⁹C) / (5.35 x 10⁻¹¹m)²

          =     ( -2.304 x 10⁻²⁸) / (5.35 x 10⁻¹¹)²

          =          8.05 x 10⁻⁸  Newton .


b).  Centripetal acceleration  = 

                                               v² / r  .

                  A  =  (2.03 x 10⁶)² / (5.35 x 10⁻¹¹)

                     =      7.7 x 10²²  m/s² .

That's an enormous acceleration ... about  7.85 x 10²¹  G's !
More than enough to cause the poor electron to lose its lunch.

It would be so easy to check this work of mine ...
First I calculated the force, then I calculated the centripetal acceleration.
I didn't use either answer to find the other one, and I didn't use  "  F = MA "
either.

I could just take the ' F ' that I found, and the 'A' that I found, and the
electron mass that I looked up, and mash the numbers together to see
whether  F = M A .

I'm going to leave that step for you.   Good luck !

Ions are atoms of the same element that have a different number of _____________.Question 13 options:

A. nuclei


B. nucleons


C. electrons


D. protons


E. neutrons

Answers

The correct option is C.

How do an atom and an ion of the same element differ?

Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.

What makes different ions of the same element different?

An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.

Which model of the atom has electrons traveling in specific paths around the nucleus? Bohr's model Rutherford's model Thomson's model Dalton's model

Answers

The model of the atom that has electrons traveling in specific paths around the nucleus is Rutherford's model.

Therefore, the correct answer is option B

J. J Thomson proposed that the atom is a sphere of positively charged matter in which negatively charged electron are embedded.

In Rutherford's model of atomic structure, the electrons moves in orbits by electrostatic attraction to the positively charged nucleus.

According to Dalton's atomic theory, atom were indestructible and indivisible  solid particle.

Bohr's model made assumption that electron can only exist in circular orbits of definite quantum energy.  

According to the question, the model of the atom that has electrons traveling in specific paths around the nucleus is Rutherford's model.

Therefore, the correct answer is option B

If the Sun has 28 times more gravity than Earth,
what is your weight on the Sun?

Answers

If someone have weight that is force due to gravity is X than on the sun it will become 28 X.

What is force?

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Mass of body is constant on any place in the universe and weight changes with acceleration due to gravity so, at sun weight will be 28 X.

If someone have weight that is force due to gravity is X than on the sun it will become 28 X.
