The data table below shows the distribution of the energies of a pendulum 0.60 s into its motion. What is the missing value?

Physics
1 answer:
ohaa [14]3 years ago
4 0
The total energy (also called mechanical energy) is the sum of the kinetic energy and potential energy:
TE = KE + PE
For this pendulum, we see that at t=0.60 s the total energy is TE=0.918 J while the potential energy is 0.054 J, so the kinetic energy (the missing value in the table) is
KE=TE-PE=0.918 J - 0.054 J =0.864 J

katen-ka-za [31]

Magnetic fields

Explanation:

The presence of magnetic fields  best explains why a magnet can act a distance on other magnets or on objects containing certain metals.

  • Magnetic fields are lines of forces around a bar magnet.
  • These lines of forces attracts and repels other magnetic bodies and metallic bodies round it.
  • Magnetic lines of forces originates at the north pole and enters in the south pole.
  • Areas around a magnetic body are bounded by force fields.
  • A magnet has permanent magnetic fields round it.

A thin glass rod is submerged in oil. What is the critical angle for light traveling inside the rod? The index of refraction for
Alekssandra [29.7K]
When light travels from a medium with higher refractive index to a medium with lower refractive index, the critical angle is the angle of incidence above which light is reflected only (no refraction occurs), and the value of this critical angle is given by
\theta_c = \arcsin ( \frac{n_2}{n_1} )
where n2 is the refractive index of the second medium and n1 is the refractive index of the first medium.

In this problem, the first medium is the glass (n_1 = 1.50), while the second medium is oil (n_2 =1.46), therefore the critical angle is given by
\theta_c = \arcsin( \frac{1.46}{1.50} )=\arcsin(0.973)=76.7^{\circ}
