If the kinetic energy of an object changes, then the collision is considered inelastic. This is regardless of whether the objects sticks together or not.
My best answer for this question would be D) inelastic, because kinetic energy is not conserved.
We can tell from the collision that it is not elastic.
Momentum is is conserved, it transfers to the other player.
Kinetic energy is not conserved, at it turns into internal friction.
I hope this helps! :)
Answer:
The copper wire stretches 6.25 cm and the steel wire stretches 3.75 cm.
Explanation:
Young's modulus is defined as:
E = stress / strain
E = (F / A) / (dL / L)
E = (F L) / (A dL)
Solving for dL:
dL = (F L) / (A E)
The wires have the same force, length, and cross-sectional area. So:
dL₁ + dL₂ = (FL/A) (1/E₁ + 1/E₂)
Given that dL₁ + dL₂ = 0.10 m, E₁ = 20×10¹⁰ N/m², and E₂ = 12×10¹⁰ N/m²:
0.10 = (FL/A) (1/(20×10¹⁰) + 1/(12×10¹⁰))
FL/A = 0.75×10¹⁰ N/m
Solving for dL₁ and dL₂:
dL₁ = (FL/A) / E₁
dL₁ = (0.75×10¹⁰ N/m) / (20×10¹⁰ N/m²)
dL₁ = 0.0375 m
dL₂ = (FL/A) / E₂
dL₂ = (0.75×10¹⁰ N/m) / (12×10¹⁰ N/m²)
dL₂ = 0.0625 m
The copper wire stretches 6.25 cm and the steel wire stretches 3.75 cm.
Answer:
Schrödinger believed that electrons could only exist in orbits, but Bohr stated that electrons could be found anywhere in the atom
Explanation: I got it right on test
Answer:
Electromagnetic Radiation
Explanation:
Electromagnetic radiation is formed by the combination of electric and magnetic fields, which propagate through space in the form of energy-carrying waves.
Electromagnetic waves have vibrations perpendicular to the direction of wave propagation. For this reason, they are classified among the transverse waves.
Electromagnetic waves travel through space, and do not need a material medium to propagate.
Main types of electromagnetic radiation.
Gamma rays: More energetic radiation. It has the highest frequency (and therefore, the shortest wavelength). They constitute a form of radioactivity.
X-rays: Radiation of less energy than gamma rays. It is used in medical examinations and in the study of metals.
Ultraviolet (UV) rays: Radiation of less energy than X-rays. It comes mainly from the sun.
Visible radiation: Radiation of lower energy than ultraviolet rays. Collect the range of frequencies that can be perceived with the view, from red to violet.
Infrared rays (IR): Radiation of less energy than visible radiation. It is emitted by hot bodies.
Microwave: Radiation of less energy than infrared. It is used in appliances and medical therapy.
TV and radio waves: Less energetic radiation. They are used in telecommunications
The energy travels in a disturbance, in an ocean that disturbance is a wave, so the wave makes energy and moves it through the water
