Using the pressure law (P1 x V1)/ T1 = (P2 x V2)/ T2 where P1= the initial pressure V1= initial volume T1= initial temperature and P2= the final pressure V2= the final volume T2 = the final temperature and temperature is always in kelvin
Answer:
1. The reason why a plane mirror forms a virtual image is because it doesn't let the light go through it, but it reflects the light, so if you go behind the plane mirror, then you won't see the rays of light since it's not letting the rays of light go behind it.
2. The image cannot be projected onto a screen also.
3. Also, the Rays of light never meet at a focus point, so hence, this is why the plane mirror forms a virtual image.
Thanks!
Answer:
I think it's because the refractive index of that medium is constant
Answer:
a) p = 25.8 10⁻¹² C m
, b) The direction of the dipole moment is directed from the negative to the positive charge, c) E = 4.65 10² N/C
Explanation:
a) The dipole moment is
p = 2qa
p = 2 4.30 10⁻⁹ 3.00 10⁻³
p = 25.8 10⁻¹² C m
b) The direction of the dipole moment is directed from the negative to the positive charge, that is, in the opposite direction to the electric field.
c) The torque is
τ = p x E
τ = p E sin θ
E = τ / p sin θ
E = 7.20 10⁻⁹ /(25.8 10⁻¹² sin 36.9)
E = 4.65 10² N/C
We calculate
τ = 15.49 10⁻¹² 4.7 10²
τ = 7.28 10⁻⁹ N m
