Given:
Mass of body = 30 kg
gravitational acceleration on the moon = 1.62 m/s
2
Weight of the body on the moon = Mass of the body×gravitational acceleration on the moon=30×1.62=48 N
What are the options for A,B,C,D? There’s arrows
The wavelength of the third line in the Lyman series, and identify the type of EM radiation
In this series, the spectral lines are obtained when an electron makes a transition from any high energy level (n=2,3,4,5... ). The wavelength of light emitted in this series lies in the ultraviolet region of the electromagnetic spectrum.
1 / lambda = R(h)* ( 
- 
)
= 109678 ( 
- 
)
= 109678 (8/9)
Lambda = 9 / (109678 * 8 )
= 102.6 * 
m = 102.6 nm

The shape of the continents had been observed, that they fit together like a puzzle; this is easy to see with Africa and South America. Volcanoes and earthquakes had been found to only erupt in certain places - at the plate boundaries. Also, similar fossils had been found where the continents may have been connected. When satellite was introduced, some plate boundaries could even be seen from outer space.
Answer:
A phenomenon!
Explanation:
That I think was observed when a Faraday cage operates to block the effects of an electric field. (RANGE SOURCE).
